COP87L88FH
8-Bit CMOS OTP Microcontrollers with 16k Memory,
Comparators, USART and Hardware Multiply/Divide
General Description
The COP87L88FH OTP (One Time Programmable) micro-
controllers are highly integrated COP8™ Feature core de-
vices with 16k memory and advanced features including
Analog comparators, and Hardware Multiply/Divide. These
multi-chip CMOS devices are suited for applications requir-
ing a full featured controller with comparators, a full-duplex
USART, and hardware multiply/divide functions, and as
pre-production devices for a masked ROM design. Lower
cost pin and software compatible 12k ROM versions are
available (COP888FH), as well as a range of COP8 software
and hardware development tools.
Family features include an 8-bit memory mapped architec-
ture, 10 MHz CKI (-XE = crystal oscillator; -TE = external
clock) 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, WATCHDOG™ and clock monitor logic, low EMI
2.7V to 5.5V operation, and 28/40/44 pin packages.
