COP884BC/COP885BC

8-Bit CMOS ROM Based Microcontrollers with 2k

Memory, Comparators, and CAN Interface

General Description

The COP884BC ROM based microcontrollers are highly in-

tegrated COP8â¢ Feature core devices with 2k memory and

advanced features including a CAN 2.0B (passive) interface

and two Analog comparators. These single-chip CMOS de-

vices are suited for applications requiring a full featured con-

troller with a CAN interface, low EMI, and an 8-bit 39 kHz

PWM timer. COP87L84BC devices are pin and software

compatible 16k OTP (One Time Programmable) versions for

pre-production, and for use with a range of COP8 software

and hardware development tools.

Features include an 8-bit memory mapped architecture, 10

MHz CKI (crystal osc) with 1Âµs instruction cycle, one multi-

function 16-bit timer/counter, 8-bit 39 kHz PWM timer with 2

outputs, CAN 2.0B (passive) interface, MICROWIRE/

PLUSâ¢ serial I/O, two Analog comparators, two power sav-

ing HALT/IDLE modes, idle timer, MIWU, software selectable

I/O options, Power on Reset, low EMI 4.5V to 5.5V opera-

tion, and 20/28 pin packages.

Note: A companion device with CAN interface, more I/O and

memory, A/D, and USART is the COP888EB.
