• Each peripheral can be individually disabled to save power

1.2 56F8357 Description

The 56F8357 is a member of the 56800E 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. Because of its low cost,

configuration flexibility, and compact program code, the 56F8357 is well-suited for many

applications. The 56F8357 includes many peripherals that are especially useful for motion control,

smart appliances, steppers, encoders, tachometers, limit switches, power supply and control,

automotive control, engine management, noise suppression, remote utility metering, industrial

control for power, lighting, and automation applications.

The 56800E core is based on a Harvard-style architecture consisting of three execution units

operating in parallel, allowing as many as six operations per instruction cycle. The MCU-style

programming model and optimized instruction set allow straightforward generation of efficient,

compact DSP and control code. The instruction set is also highly efficient for C/C++ Compilers to

enable rapid development of optimized control applications.

The 56F8357 supports program execution from internal or external memories. Two data operands

can be accessed from the on-chip data RAM per instruction cycle. The 56F8357 also provides two

external dedicated interrupt lines and up to 76 General Purpose Input/Output (GPIO) lines,

depending on peripheral configuration.
