32-BIT SINGLE CHIP BASEBAND CONTROLLER
FOR GPS AND TELEMATIC APPLICATIONS
DATA BRIEF
1 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.
■ 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
