COP888EB

8-Bit CMOS ROM Based Microcontrollers with 8k

Memory, CAN Interface, 8-Bit A/D, and USART

General Description

The COP888EB ROM based microcontrollers are highly in-

tegrated COP8

advanced features including a CAN 2.0B (passive) interface,

A/D and USART. These single-chip CMOS devices are

suited for applications requiring a full featured controller with

a CAN interface, low EMI, and versatile communications in-

terfaces. COP87L8EB/RB devices are pin and software

compatible 16k or 32k OTP (One Time Programmable) ver-

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

software and hardware development tools.

Key Features

n CAN bus interface, with Software Power save mode

n 8-bit A/D Converter with 8 channels

n Fully buffered USART

n Multi-input wake up (MIWU) on both Port L and M

n SPI Compatible Master/Slave Interface

n Quiet Design (Low Radiated Emissions)

n 8096 bytes of on-board ROM

n 192 bytes of on-board RAM

Additional Peripheral Features

n Idle timer (programmable)

n Two 16-bit timer, with two 16-bit registers supporting

n WATCHDOG and Clock Monitor

n MICROWIRE/PLUS serial I/O

I/O Features

n Software selectable I/O options (TRI-STATE

n Schmitt trigger inputs on Port G, L and M

n Packages: 44 PLCC with 31 I/O pins

CPU/Instruction Set Features

n 1 µs instruction cycle time
