The GPS baseband processor ATR0620 includes a 16-channel GPS correlator and is based on the ARM7TDMI processor core. This processor has a high-performance 32-bit RISC architecture with a high-density 16-bit instruction set and very low power consumption. 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 ATR0620 has a direct connection to off-chip memory, including flash, through the External Bus Interface (EBI).
