STA2051GO Datasheet, PDF (1/4 Pages) STMicroelectronics – Single Chip GPS Controller

STA2051GO
Features
■ Suitable for hand held accessories, portable
and personal navigation systems
■ ARM7TDMI 16/32 bit RISC CPU based host
microcontroller running at a frequency up to 32
MHz.
■ Complete Embedded Memory System:
– FLASH 256K bytes + 16K bytes (100K
erasing/programming cycles)
– RAM 64K bytes.
■ 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.
■ Power Supply:
– 3.0V to 3.6V operating supply range for
Input/Output periphery
– 3.0V to 3.6V operating supply range for A/D
Converter reference
– 1.8V operating supply range for core supply
provided by internal Voltage Regulator with
external stabilization capacitor.
■ 32 programmable General Purpose I/O
multiplexed with peripheral functions, each pin
programmable independently as digital input or
digital output.
Single Chip GPS Controller
DATA BRIEF
TQFP64 (10 x 10 x 1.4mm)
■ 4 Channels A/D for low frequency signal
monitoring (temperature, battery....)
■ Real time clock module with 32 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.
■ Four Serial Communication Interfaces (UART)
allow full duplex, asynchronous,
communications with external devices,
independently programmable TX and RX baud
rates up to 625K baud.
■ One Serial Peripheral Interfaces (SPI) allow full
duplex, synchronous communications with
external devices, master or slave operation,
max baud rate: 5.5Mb/s. One SPI may be used
as Multimedia Card interface.
■ One I²C Interfaces provide multi-master and
slave functions, support normal and fast I²C
mode (400 KHz), 7/10 bit addressing modes.
■ Wake-up unit allows exiting from powerdown
modes by detection of an event on one external
pins or on internal Real Time Clock alarm.
■ -40°C to 85°C operating temperature range
(guaranteed by correlation).
