56F8323 Features

Part 1 Overview

1.1 56F8323 Features

1.1.1 Hybrid Controller Core

• Efficient 16-bit 56800E family engine with dual Harvard architecture

• As many as 60 Million Instructions Per Second (MIPS) at 60MHz core frequency

• Single-cycle 16 × 16-bit parallel Multiplier-Accumulator (MAC)

• Four 36-bit accumulators including extension bits

• Arithmetic and logic multi-bit shifter

• Parallel instruction set with unique addressing modes

• Hardware DO and REP loops

• Three internal address buses

• Four internal data buses

• Instruction set supports both DSP and controller functions

• Controller-style addressing modes and instructions for compact code

• Efficient C compiler and local variable support

• Software subroutine and interrupt stack with depth limited only by memory

• JTAG/EOnCE debug programming interface

1.1.2 Memory

• Harvard architecture permits as many as three simultaneous accesses to program and data memory

• Flash security protection

• On-chip memory including a low-cost, high-volume Flash solution

— 32KB of Program Flash

— 4KB of Program RAM

— 8KB of Data Flash

— 8KB of Data RAM

— 8KB of Boot Flash

• EEPROM emulation capability

1.1.3 Peripheral Circuits for 56F8323

• One Pulse Width Modulator module with six PWM outputs, three Current Sense inputs and three

Fault inputs, fault-tolerant design with dead time insertion; supports both center- and edge-aligned

modes

• Two 12-bit, Analog-to-Digital Converters (ADCs), which support two simultaneous conversions

with dual, 4-pin multiplexed inputs; ADC and PWM modules can be synchronized through Timer

C, channel 2

• Temperature Sensor can be connected, on the board, to any of the ADC inputs to monitor the

on-chip temperature

• Two 16-bit Quad Timer modules (TMR) totaling seven pins: Timer A works in conjunction with

Quad Decoder 0 and Timer C works in conjunction with the PWMA and ADCA

• One Quadature Decoder which works in conjunction with Quad Timer A
