FEATURES

■

ARM7TDMI 16/32 bit RISC CPU based host

microcontroller.

■

Complete Embedded Memory System:

– FLASH 256K bytes + 16K bytes (100K eras-

ing/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 ex-

ternal 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.

■

slave functions, support normal and fast I2C

mode (400KHz), 7/10 bit addressing modes.
