1. Description
The GPS baseband processor ATR0625P 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 ATR0625P 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 ATR0625P includes full GPS SuperSense
firmware, licensed from u-blox AG, which per-
forms 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 ATR0625P is manufactured using Atmel
’s 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 ATR0625P provides a highly flexible and
cost-effective solution for GPS applications.
