56F827 Description

The 56F827 is a member of the 56800 core-based family of hybrid controllers. 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 for general purpose applications. Because of its low cost, configuration flexibility, and compact program code, the 56F827 is well-suited for many applications. The 56F827 includes many peripherals that are especially useful for applications such as: noise suppression, ID tag readers, sonic/subsonic detectors, security access devices, remote metering, sonic alarms, and telephony.
