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.
The device offers the high performance of a RISC architec-
ture while retaining the advantages of a traditional Com-
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.
