COP888GD

8-Bit CMOS ROM Based Microcontrollers with 16k

Memory and 8-Channel A/D

Family features include an 8-bit memory mapped architec-

ture, 10 MHz CKI with 1µs instruction cycle, three multi-

General Description

The COP888GD ROM based microcontrollers are highly in-

™

function 16-bit timer/counters, MICROWIRE/PLUS serial

™

tegrated COP8 Feature core devices with 16k memory

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,

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.

software selectable I/O options, WATCHDOG timer and

Clock Monitor, 2.5V to 5.5V operation, program code secu-

rity, and 44 pin package.
