UM0442 list of features 5/33 3 list of features the str750-map is a system designed for a wide spectrum of high-end applications. appreciable and innovative features are the new 12-pin socket for zigbee ? modules and the possibility to choose among four different power sources. the board mounts the str750fv2 microcontroller in lqfp100, 14x14 mm package. the pin-out of the str750fv2 microcontroller is available to the users and placed around the microcontroller itself. the list of features of the str750-map board is as follows: str750fv2 arm7tdmi-s ? 32-bit mcu zigbee ? socket for module based on sn260 34-pin motor control connector mini-usb connector both for data and for board supply battery pack connector for rechargeable battery 912 vdc standard power supply connector external 5 v power source to plug in the str750fv2 pin-out 3-axis mems accelerometer lis3lv02dq analog temperature sensor stlm20 graphic lcd strip line connector db9 standard male can connector db9 standard male rs232 connector jtag connector for programmi ng and debuggi ng capabilities reset and wake-up push buttons 2 switches for memory boot capabilities i 2 c connector bspi connector 6 user leds potentiometer on adc channel 2 general purpose push buttons each of this features or functionalities is fully explained in this user manual. 4 hardware configuration and functionality 4.1 power source selector the str750-map evaluation board is provided with a power source selector that allows the user to choose between four different ways to power the board includ ing the possibility to recharge the external battery pack while the board is powered through the standard power 9 vdc power supply or the mini-usb connector.
hardware configuration and functionality UM0442 6/33 the configuration of the power source selector as appears in the silkscreen (consider the following abbreviations as a legend for the picture below) is as follows: bat: the battery pack is selected as power source. to do this, close the related jumper and connect the battery pack by plugging in its connector as appropriate (see section 4.2: battery pack power source ). ext: the external 5 v power source is selected as power source. usb: plug in this jumper once the board is connected to a computer through the mini-usb connector in the upper side of the board. pwr: the standard 9 vdc power connector is chosen and a voltage regulator (l7805ab) provides the 5 v supply to all the components in the board. figure 3. power source selector and jumper legend it is strongly recommended to not select more than one power source at a time. this is to prevent possible power source failures, with the consequence to propagate these failures to the board components. 4.2 battery pack power source the battery pack is selected by closing the appropriate jumper as shown in the previous section. in order to supply the str750-map the following two steps are required: plug the battery pack connector onto the str750-map, using the 2-pin connector named battery in the board silkscreen. configure the 3-pin strip-line selector s7 as follows: close the middle point of the s7 selector with the point 3 (left side of the s7). in this way, the battery pack is linked to the l6920d step-up converter in order to furnish the right voltage to all the components (see figure 4 ). figure 4. the selector s7 allows the str750-map to be supplied from the battery pack as an alert feature, an led is placed to give a warning if a low battery level occurs (led d10). the two types of batteries that can be connected to the board to allow all features are the graphite anode single cell li-ion or li-polymer. the low threshold voltage detector is fixed at 2.7 v (considering the use of a battery pack at typically 3.7 v/1360 mah).
UM0442 hardware configuration and functionality 7/33 when another power source (usb, 9 vdc) is selected, it is possible to recharge the battery pack. the l6924d battery charger system performs this task. 4.2.1 how to charge the battery pack it is possible to charge a battery pack connected to the str750-map while the board is powered through the power supply or the usb connector. although the first method is outlined, the procedure to implement the charge phase is the same for both ways. first of all, the str750-map needs to be supplied. for example, plug in the 912 vdc power supply connector (closing the appropriate jumper). as a second step, connect the battery pack to the connector, without closing the correspondent jumper in the power source selector. to set up the recharging process, follow these steps: 1. close the selector s7 in the position 1-2: this is to connect the battery to the recharging circuit. 2. close the selector s8 in th e position 2-3: this is in orde r to select 5 v standard power source. 3. close the selector s9 in the position 1-2: by doing this, the l6920 and its circuitry is switched off in order to save power. figure 5. selectors configuration to recharge the battery pack 4.3 external 5 v power sourcer it is possible to plug in an external 5 v power source by closing the jumper ext in the power source selector. this feature makes the str750-map highly versatile. since this power source has no specific connectors, the only way to furnish 5 v to the str750-map, comes directly from the str750fv2 pin-out placed around the microcontroller itself. in this way, the user can make his own interface board or connect it directly to the microcontroller's pins. take care to follow these simple steps: the external 5 v can operate only if the ext (see figure 3 ) jumper is closed. after this, the 26 th pin of the connectors j1, j2, j3 and j4 placed around the microcontroller (see the following figure 6 ), is available to receive the external supply. pay attention when connecting boards outputting 600 ma as maximum current in order to preserve the str750-map functionalities from damage.
hardware configuration and functionality UM0442 8/33 figure 6. str750fv2 pin-out and ext power source locations 4.4 mini-usb connector power source in order to use the mini-usb connector as power source, close the related jumper as described in section 4.1: power source selector on page 5 (be sure that the other jumpers are open) and then plug the mini-usb cable onto the connector. this feature can have an impa ct on the battery charge ca pabilities of the str750-map as described in section 4.2 . the usb unit integrates a 48 mhz clock for data management and a usblc6-2p6 application specific device for very low c apacitance esd protection circuit (see the schematics in figure 23 ). 4.5 standard power supply connector the standard power supply connector is nam ed as pwr in the board silkscreen and, once closed, the str750-map is powered using both laboratory equipment and a common 912 vdc power supply source. this power source also impacts the ba ttery charge capab ilities of the board. 4.6 memory boot the str750-map evaluation board allows the user to run the str750fv2 choosing between 4 memory modes in order to perform the boot phase. to make the appropriate choice for your application, refer to the boot table printed onto the board silkscreen. this table is given here with the associated selectors (see ta bl e 1 ). sw1 corresponds to boot1/cs2 in the schematics, on the right side (boundary part of the board). sw2 corresponds to boot0 pin in the microcontroller and in the schematics (refer to the related schematics in figure 22 ).
UM0442 hardware configuration and functionality 9/33 following the str750fv2 datasheet, the boot table given in ta bl e 1 and figure 7 could be useful to clarify the layout. in ta b l e 1 above, the "0-0" configuration corresponds to the boot from the embedded flash memory sector "b0f0" mapped at 0h. the configuration "0-1" corresponds to the embedded sram mapped at 0h. the configuration "1-0" corresponds to the boot from the system memory mapped at 0h. finally the configuration "1-1" corresponds to the boot from external smi bank 0 mapped at 0h. figure 7. memory boot selectors and example of configuration the configuration chosen here corresponds to the mem memory model. 4.7 str750fv2 pin-out to enhance debugging features as well as th e possibility to easily connect a secondary board, the whole pin-out of the microcontroller is available to the users and located around the microcontroller. the pin-out is arranged around the microcontr oller with 4 connectors placed one per side. since the lqfp100 package is used, each connector is composed of 26 pins with the last pin as a spare for the str750fv2 pin-out. the 26 th of each connector is used as 5 v external power source when the jumper ext in the power source selector is closed (see section 4.3 for details). to facilitate the use of this pin-out, the pin correspondence is pr inted close to each connector. ta bl e 2 and figure 8 show the numbering for the connector related to pin 1 to 25 (connector je1 in the layout). the same numbering is used for the other connectors, where the last pin is connected for the external 5 v supply. ta b l e 2 describes the connector/pin-out association. table 1. boot table memory model sw2 - sw1 flash 0?0 sram 0?1 mem 1?0 smi 1-1

UM0442 hardware configuration and functionality 11/33 in applications where the 5 v supply comes from the motor control connector, all the jumpers of the power selector must be open. of course, if the 5 v is furnished from the str750-map to the mc, choose the appropriate supply from the power supply selector by closing the corresponding source. pay particular attention also when using jumper j15. it allows the user to provide 3.3 v to the mc connector, when it is closed (jumper j15 is open by default). in any case, 3.3 v cannot be supplied by the motor control connector. figure 9. 34-pin motor control connector 14 bus voltage 27 15 current phase a 108 16 none ground - 17 current phase b 106 18 none ground - 19 current phase c 104 20 none ground - 21 ntc bypass relay 204 22 none ground - 23 dissipation brake pwm 100 24 none ground - 25 vcc 5 v 5 v - 26 heat sink temperature 29 27 pfc (power factor corrector) synchronization 31 28 +3v3 3.3 v - 29 pfc pwm 30 30 none ground - 31 encoder a 3 32 none ground - 33 encoder b 33 34 encoder index 1 table 3. motor control connector and str750fv2 pins correspondence connector pin name function str750fv2 pin
hardware configuration and functionality UM0442 12/33 4.9 mini-usb connector the mini-usb connector provides both data management features as well as board supply operations (board supply and battery pack recharge), see figure 10 and ta b l e 4 . figure 10. standard mini-usb connector this standard connector is defined as part of the usb-otg (usb on the go) enhancement. it features a single connector type (a or b) and peer-to-peer operations. the configuration present on the str750-map is type b, as pin 4 is not connected (nc in the table). the usb-otg is a supplement to the usb 2.0 (or usb 1.0) specifications that allow usb devices to have more flexibility in managing usb connections. as known, the standard usb (usb 1.1/2.0) uses master/slave architecture. a usb host acts as a master and a usb peripheral (aka usb device) acts as a slave. only the usb host can schedule the configuration and data transfers over the link, while the usb peripherals cannot initiate data transfers. they only respond to instructions given by a host. the usb-otg compatible devices are able to initiate the session, control the connection and exchange host/peripheral roles between each other. with this new architecture, two new protocols are introduced: srp (session request protocol) and hnp (host negotiation protocol). two new classes of devices are defined: otg a-device and otg b-device. this terminology defines which side supplies power (vbus) to the link. the otg a-device is a supplier and an otg b-device (our case) is a consumer. the default link configuration is that a-device is host and b-device is a peripheral (this may be reversed later by using hnp). these devices are fully backward compliant with usb 1.1/2.0 and behave as standard usb hosts or peripherals when connected to standard (no otg) usb devices. table 4. pins and signals correspo ndence for the mini-usb connector pin number name colour notes 1 vbus red power 2 d- white data - 3 d+ green data + 4 id - type a ? gnd/type b - nc 5gndblackground
UM0442 hardware configuration and functionality 13/33 the usb-otg standard defines only one-to-one connection. contrary to the standard usb there are no usb hubs defined by the usb-otg. connecting the usb hub between two otg devices leads to losing all usb-otg capabilities. 4.10 jtag connector to allow enabling of debug features as well as programming capabilities, the str750-map is equipped with a standard jtag connector. figure 11 below shows how the pins and the corresponding signals are placed in the jtag connector. figure 11. the jtag connector 4.11 on-board sensors as described in the features list of the board, the str750-map is provided with one 3-axis digital mems accelerometer (the lis3lv02dq) and one analog temperature sensor (the stlm20). both sensors are mounted with their package size (qfn28 and udfn4 package respectively). while the temperature sensor provides only the analog output (connected to the adc channel 0, pin number 2 in the microcontroller pin-out), the accelerometer could output both i 2 c and spi digital serial output. as a design choice, the str750-map allows the on-board accelerometer to communicate with the str750fv2 using only the i 2 c serial bus (the cs pin is fixed at 3.3 v). the board offers th e possibility to di sconnect this i 2 c bus from the accelerometer, allowing the microcontroller to communicate with external peripherals using this bus at 3.3 v as vcc with both standard and fast protocol variants. to manage these settings, refer to section 4.16: i2c and bspi connectors on page 18 . the packages are described in figure 12 , where on the left side is the qfn28 package of the accelerometer, and on the right side is the udfn4 package of the temperature sensor. refer to the device datasheet in the reference section for further details.

hardware configuration and functionality UM0442 16/33 figure 13. a female strip-line is used as lcd socket 4.14 can connector the board is equipped with a standard db9 male connector to enhance networking capabilities, especially in industrial and factory automation environments. the physical layer of the can protocol is implemented through the l9616 transceiver. it allows the peripheral to reach standard communication speeds (up to 250 kbps and up to 1 mbps) which can be done by setting the selector s5 (located close to the can connector, see figure 2 ) as appropriate. taking the middle point of this selector as a reference, and closing this one with pin number 3 (0 in the boar d silkscreen), the device runs at 1 mbps as maximum speed. closing the middle point of s5 with pin number 1 in the layout (1 in the board silkscreen), the communication speed is limited to 250 kbps. independently of the speed you select, you must close jumper jp12 to connect the termination resistor, in order to close the communication line on the str750fv2 side. jumpers jp10 and jp11 also must be closed to allow communication. they connect the tx and rx pins of the transceiver with pins 64 and 63 of the microcontroller respectively, linking the peripheral to the physical layer of the communication protocol. 5 rnotw 200 6e218 7db0210 8db1211 9db2212 10 db3 213 11 db4 214 12 db5 215 13 db6 216 14 db7 217 15 cs1 201 16 cs2 202 17 notrst 59 18 vout - 19 a - 20 k - table 8. lcd socket pin description (continued) pin no name str750fv2 pin
