2 / 31 page 2 4890H–GPS–08/08 ATR0621P 1. Description The GPS baseband processor ATR0621P includes a 16-channel GPS correlator and is based on the ARM7TDMI processor core. This processor has a high-performance 32-bit RISC architecture and very low power consump- tion. In addition, a large number of internally banked registers result in very fast exception handling, making the device ideal for real-time control applications. The ATR0621P has two USART and an USB device port. This port is compliant with the Universal Serial Bus (USB) V2.0 full-speed device specification. The ATR0621P has a direct connection to off-chip memory, including Flash, through the External Bus Interface (EBI). The ATR0621P includes full GPS firmware, licensed from u-blox AG, which performs the basic GPS operation, including tracking, acquisition, navigation and position data output. For normal PVT (Position/Velocity/Time) applications, there is no need for off-chip Flash memory or ROM. The firmware supports e.g. the NMEA ® protocol (2.1 and 2.3), a binary protocol for PVT data, configuration and debugging, the RTCM protocol for DGPS, SBAS (WAAS, EGNOS and MSAS) and A-GPS (aiding). It is also possible to store the configuration settings in an optional external EEPROM. The ATR0621P is manufactured using the Atmel® high-density CMOS technology. By combining the ARM7TDMI microcontroller core with on-chip SRAM, 16-channel GPS correlator and a wide range of peripheral functions on a monolithic chip, the ATR0621P provides a highly-flexible and cost-effective solution for GPS applications. |
