STA2051GO Single Chip GPS Controller DATA BRIEF 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. ■ ■ ■ 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 ……
