COP685BC Datasheet | National Semiconductor

Description The COP87L88CF OTP (One Time Programmable) microcontrollers are highly integrated COP8™ Feature core devices with 16k memory and advanced features including an A/D converter. These multi-chip CMOS devices are suited for applications requiring a full featured controller with an 8-bit A/D converter, and as pre-production devices for a masked ROM design. Lower cost pin and software patible 16k ROM versions are available (COP888CF) as well as a range of COP8 software and hardware development tools. Device COP87L84CF COP87L88CF Memory (bytes) 16k OTP EPROM 16k OTP EPROM RAM (bytes) 128 128 Family features include an 8-bit memory mapped architecture, 10 MHz CKI (-XE = crystal oscallator) with 1 µs instruction cycle, two multi-function 16-bit timer/counters, MICROWIRE/PLUS™ serial I/O, one 8-bit/8-channel A/D converter with prescaler and both differential and single ended modes, two power saving HALT/IDLE modes, idle timer, MIWU, high current outputs, software selectable I/O options, WATCHDOG™ timer and Clock Monitor, 2.7V to 5.5V operation and 28/40/44 pin packages.
