ATR0630 [Preliminary]

1. Description

The ATR0630 is a low-power, single-chip GPS receiver, especially designed to meet the

requirements of mobile applications. It is based on Atmel’s ANTARIS

™

4 technology and inte-

grates an RF front-end, filtering, and a baseband processor in a single, tiny 7 mm × 10 mm

96 pin BGA package. Providing excellent RF performance with low noise figure and low power

consumption.

Due to the fully integrated design, just an RF SAW filter, a GPS XTAL (no TCXO) and blocking

capacitors are required to realize a stand-alone GPS functionality.

The ATR0630 includes a complete GPS firmware, licensed from u-blox AG, which performs the

GPS operation, including tracking, acquisition, navigation and position data output. For normal

PVT (Position/Velocity/Time) applications, there is no need for external Flash- or ROM-memory.

The firmware supports the possibility to store the configuration settings in an optional external

EEPROM.

Due to the integrated ARM7TDMI processor and an intelligent radio architecture, the ATR0630

operates in a complete autonomous mode, utilizing on chip AGC in closed loop operation.

For maximum performance, we recommend to use the ATR0630 together with a low noise

amplifier (e.g. ATR0610).

The ATR0630 supports assisted GPS.
