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, power management,

and medical monitoring 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 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 key application-specific feature of the 56F8014 is the inclusion of one Pulse Width Modulator (PWM)

module. This module incorporates three complementary, individually programmable PWM signal output

pairs and is also capable of supporting five independent PWM functions to enhance motor control

functionality. Complementary operation permits programmable dead time insertion, and separate top and

bottom output polarity control. The up-counter value is programmable to support a continuously variable
