1.2 56F8014 Description

The 56F8014 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 56F8014 is well-suited for many applications.

The 56F8014 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 supplies, power management, and medical monitoring applications.

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 56F8014 supports program execution from internal memories. Two data operands can be accessed

from the on-chip data RAM per instruction cycle. The 56F8014 also offers up to 26 General Purpose

Input/Output (GPIO) lines, depending on peripheral configuration.

The 56F8014 Digital Signal Controller includes 16KB of Program Flash and 4KB of Unified

Data/Program RAM. Program Flash memory can be independently bulk erased or erased in pages.

Program Flash page erase size is 512 Bytes/256 Words.

A full set of programmable peripherals—PWM, ADCs, SCI, SPI, I2C, Quad Timer—support various

applications. Each peripheral can be independently shut down to save power. Any pin in these peripherals

can also be used as a General Purpose Input/Outputs (GPIO).

1.3 Award-Winning Development Environment

Processor ExpertTM (PE) provides a Rapid Application Design (RAD) tool that combines easy-to-use

component-based software application creation with an expert knowledge system.

The CodeWarrior Integrated Development Environment is a sophisticated tool for code navigation,

compiling, and debugging. A complete set of evaluation modules (EVMs), demonstration board kit and

development system cards will support concurrent engineering. Together, PE, CodeWarrior and EVMs
