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 s instruction cycle, one multi-
function

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.
