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.
