This system implements a SPI based slave that responds to a host request for temperature data using a simple register read/write protocol. The reference design includes a TMP461-SP with local temperature sensing and remote diode temperature sensing of an ADC12D1620QML-SP.
The board used for this reference design is the TSW12D1620EVM-CVAL. This approach can be used as a starting point for a remote subsystem temperature and health monitor.
