Family of 16-bit CAN-enabled CompactRISC

Microcontrollers

1.0 General Description

The family of 16-bit CompactRISC™ microcontroller is

based on a Reduced Instruction Set Computer (RISC) ar-

chitecture. The device operates as a complete microcom-

puter with all system timing, interrupt logic, flash program

memory or ROM memory, RAM, EEPROM data memory,

and I/O ports included on-chip. It is ideally suited to a wide

range of embedded controller applications because of its

high performance, on-chip integrated features and low

power consumption resulting in decreased system cost.

plex Instruction Set Computer (CISC): compact code, on-

chip memory and I/O, and reduced cost. The CPU uses a

three-stage instruction pipeline that allows execution of up

to one instruction per clock cycle, or up to 25 million in-

structions per second (MIPS) at a clock rate of 24 MHz.

The device contains a FullCAN class, CAN serial interface

for low/high speed applications with 15 orthogonal mes-

sage buffers, each supporting standard as well as extend-

ed message identifiers.

The device offers the high performance of a RISC architec-

ture while retaining the advantages of a traditional Com-
