greencoder tm ur5hcfjl extremely low-power keyboard encoder for portable systems greencoder is a trademark of semtech corporation. all other trademarks belong to their respective companies. copyright ?1997-2001 semtech corporation doc5-fjl-ds-107 www.semtech.com 1 hid & system management products, keycoder tm family description features the greencoder tm ur5hcfjl is a unique, extremely low-power keyboard encoder that provides an optimum performance level for both battery-operated and desktop systems. the greencoder tm scans, debounces and encodes an 8 x 16 keyboard matrix, and provides direct drive for 3 leds and two bi-directional channels for communication with a bios- compatible system as well as an additional keyboard-compatible device. it fully supports all three ps/2 scan code sets and can implement up to three alternate keyboard layers for full 101/102 functionality. the greencoder tm employs a unique self-power management tm method that reduces the power consumption of the keyboard sub-system to an unprecedented minimum, transparently and without user intervention. in ?active? mode, the encoder consumes less than 2 ma (typ @5v). in ?sleep? mode the encoder consumes less than 2 a (typ @5v) the encoder can even nap between keystrokes and therefore it is rarely active and rarely consumes significant levels of power. a "stand-by" mode (600 a typ @5v) is entered for as long as a periodic task is active. after a programmed period of user inactivity the greencoder tm gradually dims the leds for further power savings. the greencoder tm is ideal for use in battery laptop/notebook designs and energy star compliant keyboards. r6 nl vx nc drv _reset vcc osci osco ekc1 nc opt kd kc ekc ekd cl c0 c1 c2 c3 c4 r7 sl r5 r4 r3 r2 r1 r0 c8 c9 c10 nc c5 c6 c7 gnd nc c15 c14 c13 c12 c11 40 1 6 7 12 17 18 23 28 29 34 39 plcc 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 40 39 38 37 36 35 34 33 32 31 30 29 28 27 26 25 24 23 22 21 _reset drv vx nl r6 opt kd kc ekc ekd cl c0 c1 c2 c3 c4 c5 c6 c7 gnd vcc osci osco ekc1 r7 sl r5 r4 r3 r2 r1 r0 c8 c9 c10 c11 c12 c13 c14 c15 dip r6 opt kd kc ekc ekd cl c0 c1 c2 c3 nl vx drv _reset nc nc vcc osci osco ekc1 r7 sl r5 r4 r3 r2 r1 r0 c8 c9 c10 c11 c4 c5 c6 c7 nc gnd c15 c14 c13 c12 nc qfp laptops / notebooks portable equipment medical instruments palmtops / pdas wakes-up only to respond to an external event and for a minimum period of time (2 ma current consumption) provides interface for external keyboard/keypad or other 8042- compatible device energy star compliant optimized power-saving operation with idle consumption of less than 2 a programmable led dimming for further power savings ready to interface to fujitsu's 7316, 7654,7656, and 1406 keyboards 3, 3.3, and 5 volt operation applications pin assignments

underscore before a pin mnemonic denotes an active low signal. keyboard encoder the encoder scans a keyboard organized as an 8 row by 16 column matrix for a maximum of 128 keys. smaller-size keyboards are support- ed provided that all unused row lines are pulled to vcc. when active, the encoder selects 1 of the 16 column lines (c0-c15) every 512 s and then reads the row data lines (r0-r7). a key closure is detected as a 0 in the corresponding position of the matrix. a complete scan cycle for the entire keyboard takes approximately 9.2 ms. each key found pressed is debounced for a period of 20 ms. once the key is verified, the corresponding key code(s) are loaded into the transmit buffer of the pc keyboard communication channel. scan code table sets the greencoder tm supports all three scan code table sets. scan code table set 3 allows the user to program individual key attributes such as make/break and typematic or single-touch action. for more information, refer to the ibm tech- nical reference manuals. keyboard encoder (cont ? d) mode control copyright ?1997-2001 semtech corporation doc5-fjl-ds-107 www.semtech.com 4 embedded numeric keypad the greencoder tm implements an embedded numeric keypad. the numeric keypad function is invoked by pressing the num lock key. function (fn) key a special fn key has been implemented to perform the following functions while it is held pressed: function key f1 becomes f11 function key f2 becomes f12 control left key becomes ctrl right embedded numeric keypad keys become regular keys if num lock is not set: embedded numeric keypad keys provide the same codes as a numeric keypad when the num lock is not set (arrow keys, pgup, pgdn, etc.) status led indicators the controller provides an interface for three led shift status indicators. all three pins are active low to indicate the status of the host system (num lock, caps lock and scroll lock) and are set by the system. after approximately a one- minute period of keyboard inactivity, leds are dimmed to conserve power. they are set to full brightness again upon a new keystroke. n-key rollover in this mode, the code(s) corresponding to each key press are transmitted to the host system as soon as that key is debounced, independently of the release of other keys. if a key is defined to be typematic, the corresponding make code(s) are transmitted while the key is held pressed. when a key is released, the corresponding break code(s) are then transmitted to the host system. if the released key happens to be the most recently pressed, then typematic action is terminated. there is no limitation in the number of keys that can be held pressed at the same time. however, two or more key closures, occurring within a time interval less than 5 ms, will set an error flag and will not be processed. this procedure protects against the effects of accidental key presses. ?ghost? keys in any scanned contact switch matrix, whenever three keys defining a rectangle on the switch matrix are held pressed at the same time, a fourth key positioned on the fourth corner of the rectangle is sensed as being pressed. this is known as the ? ghost ? or ? phantom ? key problem. although the problem cannot be totally eliminated without using external hardware, there are methods to neutralize its negative effects for most practical applications. keys that are intended to be used in combinations or are likely to be pressed at the same time by a fast typist (i.e., keys located in adjacent positions on the keyboard) should be placed in the same row or column of the matrix whenever possible. shift keys (shift, alt, ctrl) should not reside in the same row (or column) with any other keys. the greencoder tm has built-in mechanisms to detect the presence of a ? ghost ? key, thus eliminating the necessity of external hardware. actual key presses ? ghost ? key figure 1: ? ghost ? or ? phantom ? key problem 8042 emulation channel special handling copyright ?1997-2001 semtech corporation doc5-fjl-ds-107 www.semtech.com 5 the greencoder tm fully emulates a system ? s keyboard port, available to a standard 84/85/101/102 external keyboard or other 8042-compatible device. communication with a keyboard-compatible device is accomplished by clock and data lines via ekc and ekd pins, respectively. a third pin, ekc1 that connects to the clock line, interrupts the greencoder tm whenever the external device initiates a communication session. when power is first applied, the controller proceeds with the standard reset sequence with the external device. data and commands initiated from the external device are buffered in the greencoder tm ? s fifo along with data from the scanned matrix, and then are presented to the system as if they were coming from a single source. once they are acknowledged, commands and data from the system are then transmitted to the external device. connection of external device the greencoder tm detects the presence of an external device. if an external keyboard or other device was not connected during power-on and is connected at a later time, the greencoder tm proceeds with the normal reset routine in order to properly initialize the external device. after communication has been established, the greencoder tm continues to check for the presence of the external device. while the external device is connected, the greencoder tm does not enter the sleep mode. if the device is disconnected at a later time, the greencoder tm becomes aware of it. if a subsequent connection takes place, the greencoder tm re-initiates a reset sequence. this unique feature allows the user to connect or disconnect an external device at any time without having to reset the system. shift status leds shift status leds (num lock, caps lock and scroll lock) indicate the status of the system and are controlled by commands sent from the system. set/reset status indicator commands from the system aree executed both by the external keyboard and the scanned matrix. for example, if the user presses the caps lock key on either keyboard, the caps lock led is affected on both keyboards. the led status indicators are properly set after each new connection of an external keyboard. pc communication copyright ?1997-2001 semtech corporation doc5-fjl-ds-107 www.semtech.com 6 the greencoder tm implements all the standard functions of communication with a bios- compatible pc/xt or at / ps/2 host system. two lines, kc and kd, provide bi-directional clock and data signals. in addition, the greencoder tm supports all commands from and to the system, as described in the ibm technical reference manuals. the following table shows the commands that the system may send and their values in hex. command hex value set/reset status ed indicators echo ee invalid command ef select alternate f0 scan codes invalid command f1 read id f2 set typematic f3 rate/delay enable f4 default disable f5 set default f6 set all keys typematic f7 make/break f8 make f9 typematic/make/break fa set key type typematic fb make/break fc make fd resend fe reset ff table 2 : keyboard commands from the system (at / ps/2 protocol) these commands are supported in the at / ps/2 protocol and can be sent to the keyboard at any time. the following table shows the commands that the keyboard may send to the system. command hex value key detection 00* error/overrun keyboard id 83ab bat completion code aa bat failure code fc echo ee acknowledge (ack) fa resend fe key detection error/overrun ff** *code sets 2 and 3 **code set 1 table 3: keyboard commands to the system (at/ps/2 protocol) when an external keyboard is connected, commands from the system will also be directed to the external keyboard. presence or absence of an external device will not effect the normal operation of the greencoder tm . states of operation using the greencoder tm for system management tasks copyright ?1997-2001 semtech corporation doc5-fjl-ds-107 www.semtech.com 7 the greencoder tm provides an ideal complement to low-power chip sets targeted to the portable and mobile computing market. the greencoder tm can be used to handle several system management tasks for small, portable system designs, thus saving space and additional components for the system designer. such system management tasks include those listed below. however, since most of the system management tasks are application and hardware-dependent, detailed implementation information is outside the scope of this document. for application examples and sample schematics, contact semtech technical support. system shut-down/wake-up signal the greencoder tm can provide the system power management unit with a shut-down/wake-up signal which can be invoked either by a special keyboard combination or after a programmed period of user inactivity. note: self-power management tm is a feature protected under semtech corporation patent and copyright rights. purchase of any version of the greencoder tm encoder conveys a license to utilize the self-power management feature only through use of the greencoder tm in a ps/2-compatible keyboard subsystem. the greencoder tm has three states of operation, implemented to minimize the power consumption of the keyboard subsystem. the following diagram illustrates the three states of operation of the greencoder tm . most of the time, the greencoder tm is in the sleep state. power consumption in this state is approximately 2 a at 5 volts of operation. the greencoder tm enters the active state only when there is an event to process, such as a keystroke, a command from the system, or data from the external ps/2-compatible device. the greencoder tm enters and stays in the stand-by state if an external device is connected to the auxiliary port or if one or more leds are turned on. in the stand-by state, the greencoder tm consumes approximately 600 a at 5 volts. transition from one state to the other does not require any input from the system. sleep state stand by state active state figure 2: states of operation of ur5hcfjl copyright ?1997-2001 semtech corporation doc5-fjl-ds-107
