A Comprehensive Guide To MC56F8256MLF Microcontroller IC 16-Bit 60MHz 64KB (32K x 16) FLASH 48-LQFP (7x7)

56800E 56F8xxx Microcontroller IC 16-Bit 60MHz 64KB (32K x 16) FLASH 48-LQFP (7x7)

Introduction

The MC56F825x/MC56F824x is a member of Freescale’s family of digital signal controllers (DSCs)

based on the 56800E core. It combines, on a single chip, DSP processing power and microcontroller

functionality with a flexible set of peripherals, creating a cost-effective solution. Because of its low cost, 

configuration flexibility, and compact program code, it is well-suited for many consumer and industrial 

applications, including:

• Industrial control

• Home appliances

• Smart sensors

• Fire and security systems

• Solar inverters

• Battery chargers and management

• Switched-mode power supplies and management

• Power metering

• Motor control (ACIM, BLDC, PMSM, SR, and stepper)

• Handheld power tools

• Arc detection

• Medical devices/equipment

• Instrumentation

• Lighting ballast

The 56800E core is based on a dual 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 compilers to enable rapid

development of optimized control applications.

The MC56F825x/MC56F824x supports program execution from internal memories. Two data operands

per instruction cycle can be accessed from the on-chip data RAM. A full set of programmable peripherals

supports various applications. Each peripheral can be independently shut down to save power. Any pin

except power pins can also be configured as General Purpose Input/Output (GPIO).
