COP8SA Family

8-Bit CMOS ROM Based and One-Time Programmable

(OTP) Microcontroller with 1k to 4k Memory, Power On

Reset, and Very Small Packaging

General Description

Note: COP8SAx devices are instruction set and pin com-

patible supersets of the COP800 Family devices, and are

replacements for these in new designs when possible.

The COPSAx Rom based and OTP microcontrollers are

highly integrated COP8™ feature core devices, with 1k to 4k

memory and advanced features including low EMI. These

single-chip CMOS devices are suited for low cost applica-

tions requiring a full featured controller, low EMI, and POR.

100% form-fit-function compatible OTP versions are avail-

able with 1k, 2k, and 4k memory, and in a variety of pack-

ages including 28-pin CSP. Erasable windowed versions are

available for use with a range of COP8 software and hard-

ware development tools.

Family features include an 8-bit memory mapped architec-

ture, 10 MHz CKI with 1 µs instruction cycle, one multi-

function

16-bit

timer/counter

with

PWM

output,

MICROWIRE/PLUS™ serial I/O, two power saving HALT/

IDLE modes, MIWU, idle timer, on-chip R/C oscillator, 12

high current outputs, user selectable options (WATCH-

DOG™, 4 clock/oscillator modes, power-on-reset), low EMI

2.7V to 5.5V operation, and 16/20/28/40/44 pin packages.
