1 / 3 page ![]() 1/3 STA2056 PALINURO January 2005 This is preliminary information on a new product now in development. Details are subject to change without notice. 1 MAIN FEATURES 1.1 RF SECTION ■ Complete RF for active antenna system ■ Easily interfaced to passive antenna ■ On-chip low phase noise VCO/PLL ■ On-chip integrated loop filter and IF filter ■ Integrated Wide Dynamic Range Mixer ■ Few external components required ■ Voltage supply operation 1.8V typical ■ Low power consumption (~15mA) 1.2 BASEBAND SECTION ■ ARM7TDMI ®Core (up to 64MHz) ■ STC8 12 channels correlator ■ 256KB ROM ■ 64KB RAM (4K backup) ■ 3.3V for I/O ■ Internal 1.8V core supply ■ Low power consumption (~20mA@16MHz) 1.3 PERIPHERALS SECTION ■ 4 channel sigma delta A/D ■ 2 x UARTs 4 x timers RTC ■ GPIO pins multiplexed with alternate functions ■ I 2C ■ SPI ■ CAN 2.0 B active ■ External Memory Interface (in TQFP176 package, development only) 1.4 Operating Temperature ■ -40°C +85°C 1.5 Package ■ VFQFPN68 10mm x 10mm 1.6 GPS LIBRARY ■ GPS code available in ROM for full GPS functions and related peripherals. ■ Possible ROM customization for dedicated applications (i.e. CAN based) 1.7 EVALUATION/DEVELOPMENT KIT ■ Evaluation kit for GPS performance test. ■ Standard library available with basic commands to enable specific functions (GPIO, A/D converter) ■ Development kit for software customization with STA2056 with EMI option (STA2056B) 2 DESCRIPTION STA2056 is one chip GPS featuring the complete RF for active antenna systems and baseband functionality in a QFN 68pin package. STA2056 System-on-Chip combines GPS performances with low power consumption. Thanks to the few external components STA2056 makes the appli- cation simple and smaller.
