1. Description
The ATR0635 is a low-power, single-chip GPS receiver, especially designed to meet the
requirements of mobile applications. It is based on Atmel’s ANTARIS4 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 TCXO and blocking capacitors
are required to realize a stand-alone GPS functionality.
The ATR0635 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 ATR0635
operates in a complete autonomous mode, utilizing on chip AGC in closed loop operation.
For maximum performance, we recommend to use the ATR0635 together with a low noise
amplifier (e.g. ATR0610).
The ATR0635 supports assisted GPS.
