TSX-SP Sensor Processor

General Description
The Sensor Processor, TSX-SP, combines an accelerated 8051 processor, math coprocessors, a Cordic math engine, a 16-bit Sigma-Delta ADC, 3 programmable gain instrumentation OpAmp sensor interfaces, 3 DACs, SPI or IIC interfaces.

The Sensor Processor is a powerful, flexible single-chip solution for processing a wide variety of sensor types. The on-board DACs can be used to provide excitation waveforms to various sensor configurations.
