COP87L88FH 8-Bit CMOS OTP Microcontrollers with 16k Memory, Comparators, USART and Hardware Multiply/Divide September 1999 COP87L88FH 8-Bit CMOS OTP Microcontrollers with 16k Memory, Comparators, USART and Hardware Multiply/Divide General Description The COP87L88FH OTP (One Time Programmable) microcontrollers are highly integrated COP8™ Feature core devices with 16k memory and advanced features including Analog comparators, and Hardware Multiply/Divide. These multi-chip CMOS devices are suited for applications requiring 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. Device COP87L84FH COP87L88FH Memory (bytes) 16k OTP EPROM 16k OTP EPROM RAM (bytes) 512 512 Family features include an 8-bit memory mapped architecture, 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.
