COP87L88EB/RB Family

8-Bit CMOS OTP Microcontrollers with 16k or 32k

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

General Description

The COP87L88EB/RB Family OTP (One Time program-

mable) microcontrollers are highly integrated COP8

ture core devices with 16k or 32k memory and advanced

features including a CAN 2.0B (passive) interface, A/D and

USART. These multi-chip CMOS devices are suited for appli-

cations requiring a full featured controller with a CAN inter-

face, low EMI, and versatile communications interfaces, and

as pre-production devices for ROM designs. Pin and soft-

ware compatible 8k ROM versions (COP888EB) are avail-

able as well as a range of COP8 software and hardware de-

velopment tools.

Key Features

n CAN 2.0B (passive) bus interface, with Software Power

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 16 or 32 kbytes of on-board OTP EPROM with security

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

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 35 I/O pins;
