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: COP8SAxdevicesare instructionset andpincom-
patible supersetsofthe COP800Family devices,andare
replacementsfor thesein new designs when possible.The COPSAx Rom based and OTP microcontrollersare
highly integrated COP8™ feature core devices, with1kto4k
memoryand advanced features includinglow EMI. These
single-chip CMOS devicesare suitedforlow cost applica-
tions requiringafull featured controller,low EMI,and POR.
100% form-fit-function compatible OTP versionsare avail-
able with1k,2k, and4k memory,andina varietyof pack-
agesincluding 28-pin CSP. Erasable windowed versionsare
availableforuse witha rangeof COP8 softwareand hard-
ware development tools.
Family features includean 8-bit memory mapped architec-
ture,10 MHz CKI with1μs 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
2.7Vto 5.5V operation,and 16/20/28/40/44pin packages.
