1.2 56F8037/56F8027 Description

The 56F8037/56F8027 is a member of the 56800E core-based family of Digital Signal Controllers (DSCs).

It combines, on a single chip, the processing power of a DSP and the functionality of a microcontroller

with a flexible set of peripherals to create an extremely cost-effective solution. Because of its low cost,
