COP888FH

8-Bit CMOS ROM Based Microcontrollers with 12k

Memory, Comparators, USART and Hardware

Multiply/Divide

General Description

The COP888FH Family of ROM based microcontrollers are

highly integrated COP8™ Feature core devices with 12k

memory and advanced features including Analog compara-

tors, and Hardware Multiply/Divide. These single-chip

CMOS devices are suited for more complex applications re-

quiring a full featured controller, low EMI, two comparators, a

full-duplex USART, and hardware multiply/divide functions.

COP87L88FH devices are pin and software compatible (dif-

ferent V

CC range) 16k OTP (One Time Programmable) ver-

sions 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 1µs instruction cycle, hardware

multiply/divide functions, three multi-function 16-bit timer/

counters with PWM, full duplex USART, MICROWIRE/

PLUS™, two Analog comparators, two power saving HALT/

IDLE modes, MIWU, idle timer, high current outputs,

software selectable options WATCHDOG™ and clock/

oscillator mode, low EMI 2.5V to 5.5V operation, and 28/

40/44 pin packages.
