General Description
The COP87L88GG OTP microcontroller is a member of the COP8TM feature family using an 8-bit core architecture. It is pin and software compatible to the mask ROM COP888GG product family.

Features
■ Full duplex UART
■ Three 16-bit timers, each with two 16-bit registers supporting:
    — Processor independent PWM mode
    — External event counter mode
    — Input capture mode
■ 16 kbytes on-board OTP EPROM with security feature
■ 512 bytes on-board RAM

Additional Peripheral Features
■ Idle Timer
■ Multi-Input Wakeup (MIWU) with optional interrupts (8)
■ WATCHDOGTM and clock monitor logic
■ Two analog comparators
■ MICROWIRE/PLUSTM serial I/O

I/O Features
■ Memory mapped I/O
■ Software selectable I/O options (TRI-STATEÉ output, push-pull output, weak pull-up input, high impedance input)
■ Schmitt trigger inputs on ports G and L
■ Packages:
    — 40 DIP with 36 I/O pins
    — 44 PLCC with 40 I/O pins

CPU/Instruction Set Features
■ 1 ms instruction cycle time
■ Fourteen multi-source vectored interrupts servicing
    — External interrupt with selectable edge
    — Idle Timer T0
    — Three Timers (each with 2 interrupts)
    — MICROWIRE/PLUS
    — Multi-Input Wakeup
    — Software trap
    — UART (2)
    — Default VIS (default interrupt)
■ Versatile and easy to use instruction set
■ 8-bit Stack Pointer SP—(stack in RAM)
■ Two 8-bit register indirect data memory pointers (B and X)

Fully Static CMOS
■ Two power saving modes: HALT and IDLE
■ Single supply operation: 2.7V–5.5V
■ Temperature ranges: b40§C to a85§C

Development Support
■ Emulation device for the COP888GG and COP888HG
■ Real time emulation and full program debug offered by MetaLink Development System
