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-

, 4 clock/oscillator modes, power-on-reset), low EMI
2.7V to 5.5V operation, and 16/20/28/40/44 pin packages.
