Family of CompactRISC 16-Bit Microcontrollers
1.0
The family of CompactRISC microcontrollers are gener-
al-purpose 16-bit microcontrollers based on a Reduced In-
struction Set Computer (RISC) architecture. The device
operates as a complete microcomputer with all system tim-
ing, interrupt logic, flash program memory or ROM memo-
ry, 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.
General Description
The family of CompactRISC 16-bit microcontrollers offer
the high performance of a RISC architecture while retain-
ing the advantages of a traditional Complex 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 20 million instructions per second (MI-
PS) at a clock rate of 20 MHz.
