1. Description
The GPS baseband processor ATR0625 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 con-
sumption. 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 ATR0625
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 ATR0625 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 the possibility to store the configuration set-
tings in an optional external EEPROM. For customer-specific applications, a Software
Development Kit is available.
The ATR0625 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 ATR0625 provides a highly flexible
and cost-effective solution for GPS applications.
