MC56F8023 Datasheet PDF - Freescale

●56F8023 Description

●The 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  56F8023 is well-suited for many applications. The 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.
