Device Description

The 56F8346 and 56F8146 are members of the 56800E core-based family of controllers. Each combines, on a single chip, the processing power of a Digital Signal Processor (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, configuration flexibility, and compact program code, the 56F8346 and 56F8146 are well-suited for many applications. The devices include many peripherals that are especially useful for motion control, smart appliances, steppers, encoders, tachometers, limit switches, power supply and control, automotive control (56F8346 only), engine management, noise suppression, remote utility metering, industrial control for power, lighting, and automation applications.
