Floating point DSP processor in MCM...

Floating point DSP processor in MCM single package

This module is based on 21020F DSP based core for embedded applications. It is an opened architecture that can be cascaded in large system thanks to 1355 high-speed links.

It is a QFP mono-cavity Multi Chip Module, designed in a radiation tolerant technology, qualified for space applications.

The MCM mono cavity hosts all the chips (µP, ASIC, SRAM, SMCS)
