We are developing a radiation tolerant, mixed-signal microcontroller for applications exposed to the Martian surface thermal environment. The part can be used for spacecraft/rover engineering data collection, parameter monitoring, and fault detection at the sensor and needs minimal external support circuits. The 8-bit microcontroller includes timer resources, three serial communications ports, a 16-bit programmable digital interface, an 8-level interrupt controller, and I/sup 2/C master/slave bus interface. Mixed signal peripherals include a 16-channel, 10-bit successive approximation A/D converter, 10-bit D/A converter, programmable gain amplifier, and voltage reference. All memory interfaces use a 13-bit wide two-bit error detection, single-bit error correction code for each byte. There is an internal 512 /spl times/ 13 bit scratchpad static random access memory and 2 Ki /spl times/ 13 bit electrically erasable programmable read only memory.
