COP888CF
8-Bit CMOS ROM Based Microcontrollers with 4k
Memory and A/D Converter
General Description
The COP888CF ROM based microcontrollers are highly in-
tegrated COP8™ Feature core devices with 4k memory and
advanced features including an A/D Converter. These single-
chip CMOS devices are suited for applications requiring a
full featured controller with an 8-bit A/D converter. Pin and
software compatible (different V_CC range) 16k/32k OTP
(One Time Programmable) versions are available
(COP87L88CF Family) for pre-production, and for use with a
range of COP8 software and hardware development tools.
Family features include an 8-bit memory mapped architec-
ture, 10 MHz CKI with 1 µs instruction cycle, two multi-
function 16-bit timer/counters, MICROWIRE/PLUS™ serial
I/O, one 8-bit/8-channel A/D converter with prescaler and
both differential and single ended modes, crystal or R/C os-
cillator, two power saving HALT/IDLE modes, idle timer,
MIWU, high current outputs, software selectable I/O options,
WATCHDOG™ timer and Clock Monitor, 2.5V to 6.0V opera-
tion and 28/40/44 pin packages.
