1.2 56F8033/56F8023 Description

The 56F8033/56F8023 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, configuration flexibility, and compact program code, the 56F8033/56F8023 is well-suited

for many applications. The 56F8033/56F8023 includes many peripherals that are especially useful for

industrial control, motion control, home appliances, general-purpose inverters, smart sensors, fire and

security systems, switched-mode power supply, power management, and medical monitoring

applications.
