Features:

` ARM7TDMI 16/32 bit RISC CPU based host microcontroller.
` Complete Embedded Memory System:
   FLASH 256K bytes + 16K bytes (100K erasing/ programming cycles)
   RAM 64K bytes.
` External memory interface provides glueless support for up to four banks of external SRAM, FLASH, ROM.
` 12 channel GPS correlation DSP: no TCXO required
   RTCA-SC159 / WAAS / EGNOS support
` GPS performance
   accuracy: stand alone <30m; differential <1m; surveying <1cm
   time to first fix: autonomous start 90s; cold start 45s; warm start 7s; obscuration 1s.
` CMOS M8T (0.18 um) technology.
` -40°C to 85°C operating temperature range.
` 144-pin TQFP144 package or 64-pin TQFP64 package
` Power Supply:
   2.7V to 3.6V operating supply range for Input/ Output periphery
   3 V to 3.6V operating supply range for A/ D Converter reference
   1.8V operating supply range for core supply provided either by internal Voltage Regulator with external stabilization capacitor, or by external supply for higher power efficiency.
` 0-66MHz internal clock frequency managed by a Reset and Clock Control Unit; the unitisable to provide low power modes (WAIT, SLOW, STOP, STANDBY) and to generate the internal clock from the external reference through integrated PLL.
` 48 programmable General Purpose I/O, each pin programmable independently as digital input or digital output; 40 (30 in TQFP64) are multiplexed with peripheral functions; 16 can generate an interrupt on input level/transition.
` Real time clock module with 3 2 KHz low power oscillator and separate power supply to continue running during stand-by mode.
` 16-bit Watchdog Timer with 8 bits prescaler for system reliability and integrity.
` CAN module compliant with the CAN specification V2.0 part B (active). The bit rate can be programmed up to 1 MBaud.
` Four16-bit programmable Timers with 7 bit prescaler, up to two input capture/output compare, one pulse counter function, one PWM channel with selectable frequency each.
` 4 channels 12-bit sigma-delta Analog to Digital Converter, single channel or multi channel conversion modes, single-shotor continuous conversion modes, sample rate1KHz (4 KHz when single channel), conversion range 0-2.5V.
` Three Serial Communication Interfaces (UART) allow full duplex, asynchronous, communications with external devices, independently programmable TX and RX baud rates up to 625K baud.
` One UART adapted to suit Smart Card interface needs, for asynchronous SC as defined by ISO 7816-3; it includes SC clock generation.
` Two Serial Peripheral Interfaces (SPI) allow full duplex, synchronous communications with external devices, master or slave operation, max baud rate: 8Mb/s. One SPI may be used as Multimedia Card interface.
` Two I²C Interfaces provide multi-master and slave functions, support normal and fast I²C mode (400KHz), 7/10 bit addressing modes.
One I²C Interface is multiplexed with one SPI, so either 2xSPI+1xI²C or 1xSPI+2xI²C may be used at a time.
` USB unit V1.1 compliant, software configurable end point setting, USB Suspend/Resume support. (TQFP144 only)
` High Level Data Link Controller (HDLC) unit supports full duplex operating mode, NRZ, NRZI, FM0 and MANCHESTER modes, internal 8bit Baud Rate Generator.
