ATR0625 [Preliminary]

1.

Description

The GPS baseband processor ATR0625 includes a 16-channel GPS correlator and is based

on the ARM7TDMI

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

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.
