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,
