COP87L88RG

8-Bit One-Time Programmable (OTP) Microcontroller with

32 Kbytes of Program Memory

Schmitt trigger inputs on ports G and L

General Description

The COP87L88RG is a member of the COP8^TMOTP micro-

Packages:

Ð 44 PLCC with 40 I/O pins

controller family. It is pin and software compatible to the

Ð 40 DIP with 36 I/O pins

mask ROM COP888GG product family.

CPU/Instruction Set Features

1 ms instruction cycle time

Key Features

Fourteen multi-source vectored interrupts servicing

Ð External interrupt

Ð Idle timer T0

Full duplex UART

Three 16-bit timers, each with two 16-bit registers

supporting:

Ð Two timers (each with 2 interrupts)

Ð Processor independent PWM mode

Ð MICROWIRE/PLUS

Ð External event counter mode

Ð Multi-Input Wake Up

Ð Software trap

Ð Input capture mode

32 kbytes on-board EPROM with security feature

Ð UART (2)

Ð Default VIS (default interrupt)

Note: Mask ROMed devices with equivalent on-chip features and pro-

gram memory sizes of 4k, 8k, 16k, 20k, and 24k are available (see

Versatile instruction set with true bit manipulation
