COP688EG/COP684EG/COP888EG/COP884EG/

COP988EG/COP984EG 8-Bit Microcontroller

with UART and Three Multi-Function Timers

Packages:

Ð 28 SO or 28 DIP, each with 24 I/O pins

General Description

The COP8^TMfeature family of microcontrollers use an 8-bit

Ð 40 DIP with 36 I/O pins

single-chip core architecture fabricated with National Semi-

Ð 44 PQFP with 40 I/O pins

conductor’s M CMOS^TMprocess technology. The

COP888EG/COP884EG are members of this expandable

8-bit core processor family of microcontrollers. (Continued)

Ð 44 PLCC with 40 I/O pins

CPU/Instruction Set Features

1 ms instruction cycle time

Key Features

Fourteen multi-source vectored interrupts servicing

Ð External Interrupt with selectable edge

Ð Idle Timer T0

Ð Three Timers (each with 2 Interrupts)

Ð MICROWIRE/PLUS

Ð Multi-Input Wake-Up

Ð Software Trap

Ð UART (2)

Ð Default VIS (default interrupt)

Full duplex UART

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

supporting

Ð Processor Independent PWM mode

Ð External Event counter mode

Ð Input Capture mode

Quiet design (low radiated emissions)

8k bytes on-board ROM

256 bytes on-board RAM

Versatile and easy to use instruction set

8-bit Stack Pointer (SP) stack in RAM

Additional Peripheral Features

Two 8-bit Register Indirect Data Memory Pointers

(B and X)

Idle Timer

Multi-Input Wake-Up (MIWU) with optional interrupts (8)

Fully Static CMOS

Two analog comparators

WATCHDOG^TMand clock monitor logic

MICROWIRE/PLUS^TMserial I/O

Two power saving modes: HALT and IDLE

Low current drain (typically 1 mA)

Single supply operation: 2.5V to 6.0V

I/O Features

Temperature ranges: 0 C to 70 C, 40 C to 85 C,

Memory mapped I/O

55 C to 125 C

Software selectable I/O options (TRI-STATE Output,

Push-Pull Output, Weak Pull-Up Input, High Impedance

Input)

Development Support

Emulation and OTP devices

Schmitt trigger inputs on ports G and L

Real time emulation and full program debug offered by

MetaLink Development System
