COP888GD
8-Bit CMOS ROM Based Microcontrollers with 16k
Memory and 8-Channel A/D
General Description
The COP888GD ROM based microcontrollers are highly in-
tegrated COP8⢠Feature core devices with 16k memory
and advanced features including an A/D Converter. These
multi-chip CMOS devices are suited for applications requir-
ing a full featured controller with an 8-bit A/D converter, and
as pre-production devices for a masked ROM design. Pin
and software compatible 16k or 32k OTP EPROM versions
are available (COP87L88GD/RD Family) for pre-production,
and for use with a range of COP8 software and hardware de-
velopment tools.
Family features include an 8-bit memory mapped architec-
ture, 10 MHz CKI with 1µs instruction cycle, three 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, two power saving
HALT/IDLE modes, MIWU, idle timer, high current outputs,
software selectable I/O options, WATCHDOG⢠timer and
Clock Monitor, 2.5V to 5.5V operation, program code secu-
rity, and 44 pin package.
