COP888FH  
8-Bit CMOS ROM Based Microcontrollers with 12k  
Memory, Comparators, USART and Hardware  
Multiply/Divide  
Family features include an 8-bit memory mapped architec-  
General Description  
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/  
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 VCC range) 16k OTP (One Time Programmable) ver-  
sions for pre-production , and for use with a range of COP8  
software and hardware development tools.  
PLUS , two Analog comparators, two power saving HALT/  
IDLE modes, MIWU, idle timer, high current outputs,  
software selectable options WATCHDOG  
oscillator mode, low EMI 2.5V to 5.5V operation, and 28/  
40/44 pin packages.
