AST-400AST-400 (8.2mm x 8.2mm)
AST-400 is a complete GPS-SBAS module targeted at applications that require an extremely small GPS footprint. AST-400 combines a highly integrated GPS-SBAS RF front-end with a high performance GPS-SBAS digital baseband/processor along with the necessary discrete components into a single package for ease of integration into target application hardware.

The GPS-SBAS RF front-end is designed for GPS C/A receivers.

It has an in-built low noise amplifier (LNA), single down conversion stage, automatic gain controlled amplifier (AGC), on-chip IF band pass filter and a 2-bit analog-to-digital converter (ADC). In addition, it has in-built protection/detection circuitry for accidental short/open of the active GPS antenna.

The digital baseband is a revolutionary digital integrated circuit that combines a high performance GPS Correlator, ARM7 core and a host of rich peripherals. It delivers unmatched performance in conjunction with the RF front-end.

AST-400 supports USB 2.0 Full Speed device, SPI, TWI, Timers, GPIO and Battery backed counter/RTC.

AST-400 is available in a 8.2mm x 8.2mm FBGA package. It is RoHS certified and is qualified over the industrial temperature range of –40°C to +85°C.
