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.
