8-Bit CMOS OTP Microcontroller with 16k Memory and High Resolution A/D
COP8ACC7
8-Bit CMOS OTP Microcontroller with 16k Memory and
High Resolution A/D
General Description

The COP8ACC7 OTP(One Time Programmable) microcon-
trollersare highly integrated COP8™ Feature core devices
with16k memoryand advanced features includinga High-
Resolution A/D. This multi-chip CMOS deviceis suitedfor
applications requiringafull featured controller witha high
resolutionA/D (onlyone external capacitor required),andfor
pre-production devicesfora ROM design.Pinand software
compatible (different VCC range)4k ROMversionsare avail-
able(COPACC5). Erasable windowed versionsare available
forusewitha rangeof COP8 softwareand hardware devel-
opment tools.
Family features includean 8-bit memory mapped architec-
ture,4 MHzCKI with2.5μs instruction cycle,two external
clock options (–XE =Crystal; –RE =RC),6 channelA/Dwith
12-bit resolution, analog capture timer, analog current
sourceand VCC/2 reference,one multi-function 16-bit timer/
counter, MICROWIRE/PLUS™ serialI/O,two power saving
HALT/IDLE modes, MIWU, high current outputs, software
selectableI/O options, WATCHDOG™ timerand ClockMoni-
tor, 2.7Vto 5.5V operation, program code security, and
20/28pin packages.
