Description

This reference design illustrates the fact that several spacecraft projects provide a system health status telemetry that ground personnel monitor in real time. This reference design shows an example using a digital output temperature sensor to acquire temperature data on a sub-system using a radiation hardened MSP430FR5969-SP microcontroller (MCU). 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.

Features
  • Local temperature sensing with ±2°C accuracy
  • Remote temperature sensing with ±1.5°C accuracy
  • Ultra-low power radiation hardened MCU
  • I2C temperature sensor output(TMP461-SP)
  • SPI-based slave interface to host
