ZWIR4512 modules are available with a preprogrammed co mmand interface, allowing modem - like communic ation based on simple commands sent over a serial interface. alternatively, the module is freely programmable on the basis of an application programming interface ( api ) that exposes abstract communication functionality to the programmer. b oth software opti ons offer secure communication on the basis of the ip security (ipsec) protocol suite. additionally, an implementation of the internet key exchange protocol version 2 (ikev2) is provided, in order to make key management as easy as possible. ipsec and ikev2 are the mandated standards for securing ipv6 networks. r efer to zwir45 xx application note ? using ipsec and ikev2 in 6lowpans for more detailed information about ipsec and ikev2.
ZWIR4512 datasheet ? 2016 integrated device technology, inc. 8 january 27, 2016 the module comprises an stm32f103rc arm ? cort ex? - m3 microcontroller from st m icroelectronics and a zwir4502 transceiver from idt . these components ensure leading - edge performance values at very low power consumption. the module provides a hardware - programmed 64 - bit mac address that is guaranteed to be globally unique. 2.1. radio tra nsceiver the module includes idt ?s zwir4502 radio transceiver. this circuit performs modulation and demodulation of outgoing and incoming data, respectively. the mo dulation scheme is configurable according to the ieee802.15.4 standard. the radio transc eiver is never accessed directly by application code. this task is performed by the communication stack , whic h encapsulates such low - level functionality in abstract functions. 2.2. microcontroller the protocol stack and the user application are executed on an s tm32f103 r c microcontroller (mcu) from st microe lectronics. it provides 256 kb f lash and 48 kb sram memory. the mcu provides a rich set of peripherals and a number of general purpose input/output (gpio) ports. the gpio ports of the module are directly conne cted to the gpios of the mcu. r efer to table 4 . 1 for an exact mapping. 2.2.1. mcu core the mcu core is an arm ? cortex ?- m3. this is a 32 - bit risc core with a performance of 1.25 dmips/mhz. using idt ? s software stack , t he maximum operating frequency is 64 mhz. this allows for computational intensive applications. in order to save power , the core can be shut of f completely, waking up only on external activity. 2.2.2. peripherals and interfaces the module was designed to make max imum use of the controller ?s internal peripherals. up to 21 digital general purpose i/os can be used by the application. most of these i/os have alternative functions. some of them are 5v - tolerant. table 4 . 1 shows the most commonly used functions available for each interface. table 4.3 shows all functionalities on a single page, indicating which peripherals m ust not be used in parallel as their gp i os are interfering. in addi tion to communication interfaces, the module also provides signal conversion peripherals. three analog - to - digital converters (adcs), two digital - to - analog converters (dacs) and two pulse - width modulation (pwm) peripherals are available. 2.2.3. programming and deb ugging programming and debugging the module is typically done via jtag. all required mcu ports are connected to module pins for that purpose. alternatively, s erial w ire d ebug (swd) can be used for programming and debugging. this requires just two pins that have to be reserved, providing two additional gpio pins. alternatively, if debug functionality is not required, it is possible to program the module over a two - wire uart interface. for that purpose , the mcu ? s internal boot - loader must be started. this is done by holding the b sel pin of the module high while a reset is performed or the module is powered on. r efer to the mcu documentation for more information about serial programming.
ZWIR4512 datasheet ? 2016 integrated device technology, inc. 9 january 27, 2016 2.3. firmware 2.3.1. serial command interface ( s ci) firmware a module programmed with the serial command interface firmware acts as a network processor . in this configuration, the module is controlled over a serial interface that is spi, usb, or one of the two uarts . the s ci firmware provides all standard communication functions for data t ransmission and reception , as well as all security functions and o ver - the - a ir u pdate (otau) functionality . access to internal peripherals is limited to digital control of the gpio pins . typically, an external microcontroller or a pc is required to control module operation. however, for simple sensing or acting applications , it is also possible to configure the module to run autonomously without the need for an external controller. r efer to the zwir45xx serial command interface manual for further information . 2.3.2. c application programming interface (c - api) a c - api is provided for applications that should run directly on the embedded microcontroller. communication and security functionalities are encapsulated in a set of l ibraries that export functions for accessi ng and controlling them. the library architecture is modular, allowing tailoring applications to user needs. application s running on the microcontroller can make use of the rich set of peripherals that are provided by the controller. depending on the libra ry configuration, there are up to 192 kb of f lash and 32 kb of ram available for the user application. this is sufficient even for complex applications with high memory needs. if over - the - air update (otau) functional ity is required, the amount of f lash ava ilable for user applications is reduced to one half. for further information on c - api programming and otau , please refer to the zwir45 1 x programming guide and the zwir45xx over - the - a ir update manual . 2.4. power modes the ZWIR4512 module provides a set of operat ing modes with different capabilities and power requirements. this document only highlights the main features of these operating modes. table 2 . 1 gives an overview of the characteristics of the available power mode s. see section 1.2.2 for a table of typical current consumption in the different modes. r efer to the zwir451 x programming guide for detailed usage instructions for the low - power modes .
