Rad-hard MCUs link straight to rad-hard MRAM

New radiation-hardened and radiation-tolerant MCS8051-compatible MCUs interface with Honeywell's new radiation-hardened magnetic RAM, yielding a two-chip system solution.

Silicon Laude (pronounced "laudee") has developed the world's first, and only, radiation-hardened and radiation-tolerant MCS8051 instruction-compatible microcontrollers that can directly interface with Honeywell's new HXNV-0100 64K x 16bit radiation-hardened magnetic RAM (MRAM), yielding an unprecedented two-chip, radiation-hardened/tolerant microcontroller solution capable of reliable operation in 300krads (Si) total ionising-dose (TID) environments.

Dubbed the SL80RT051-AX001 for the radiation-tolerant version, and SL80RH051-AF001 for the radiation-hardened version (or SL80RX051 collectively), the microcontrollers are implemented in Actel space-qualified RTAX-S and Aeroflex radiation-hardened UT6325 FPGAs (respectively).

Engineered specifically for the harsh environments of space and with applications developers in min
