Part 1 Overview

1.1 56F8345 Features

1.1.1 Digital Signal Processing Core

• Efficient 16-bit 56800E family hybrid controller 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 DSP 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 feature

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

— 128KB of Program Flash

— 4KB of Program RAM

— 8KB of Data RAM

— 8KB of Boot Flash

• EEPROM emulation capability

1.1.3 Peripheral Circuits for 56F8345

• Two Pulse Width Modulator modules, each with six PWM outputs, three Current Sense inputs, and

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

edge-aligned modes

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

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

C, channels 2 and 3

• Two four-input Quadrature Decoders or two additional Quad Timers

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

on-chip temperature

• Four dedicated general-purpose Quad Timers totaling six dedicated pins: Timer C with two pins and

Timer D with four pins

• Optional On-Chip Regulator
