COP87L88CF
8-Bit CMOS OTP Microcontrollers with 16k Memory and
A/D Converter
General Description
The COP87L88CF OTP (One Time Programmable) micro-
controllers are highly integrated COP8
TM
Feature core de-
vices with 16k memory and advanced features including an
A/D converter. These multi-chip CMOS devices are suited
for applications requiring a full featured controller with an
8-bit A/D converter, and as pre-production devices for a
masked ROM design. Lower cost pin and software compat-
ible 16k ROM versions are available (COP888CF) as well as
a range of COP8 software and hardware development tools.
Family features include an 8-bit memory mapped architec-
ture, 10 MHz CKI (-XE = crystal oscallator) with 1 s instruc-
tion
cycle,

multi-function
16-bit
timer/counters,
MICROWIRE/PLUS
TM
serial I/O, one 8-bit/8-channel A/D
converter with prescaler and both differential and single
ended modes, two power saving HALT/IDLE modes, idle
timer, MIWU, high current outputs, software selectable I/O
options, WATCHDOG
TM
timer and Clock Monitor, 2.7V to
5.5V operation and 28/40/44 pin packages.
