COP8ACC5
8-Bit CMOS ROM Based Microcontrollers with 4k
Memory and High Resolution A/D
General Description
The COP8ACC5 ROM based microcontrollers are highly in-
tegrated COP8™ Feature core devices with 4k memory and
advanced features including a High-Resolution A/D. These
single-chip CMOS devices are suited for applications requir-
ing a full featured, low EMI controller with an A/D (only one
external capacitor required). COP8ACC7 devices are pin
and software compatible (different V_CC range) 16k OTP
EPROM versions for pre-production. Erasable windowed
versions are available for use with a range of COP8 software
and hardware development tools.
Family features include an 8-bit memory mapped architec-
ture, 4 MHz CKI with 2.5µs instruction cycle, 6 channel A/D
with 12-bit resolution, analog capture timer, analog current
source and V_CC/2 reference, one multi-function 16-bit timer/
counter, MICROWIRE/PLUS serial I/O, two power saving
HALT/IDLE modes, MIWU, high current outputs, software
selectable I/O options, WATCHDOG™ timer and Clock Moni-
tor, Low EMI 2.5V to 5.5V operation and 20/28 pin packages.
