COP888CF 8-Bit CMOS ROM Based Microcontrollers with 4k Memory and A/D Converter
General Description
The COP888CF ROM based microcontrollers are highly integrated COP8TM Feature core devices with 4k memory and advanced features including an A/D Converter. These singlechip CMOS devices are suited for applications requiring a full featured controller with an 8-bit A/D converter. Pin and software compatible (different VCC range) 16k/32k OTP (One Time Programmable) versions are available (COP87L88CF Family) for pre-production, and for use with a range of COP8 software and hardware development tools. Device COP884CF COP984CF COP888CF COP988CF Memory 4k bytes ROM 4k bytes ROM 4k bytes ROM 4k bytes ROM RAM 128 bytes 128 bytes 128 bytes 128 bytes Family features include an 8-bit memory mapped architecture, 10 MHz CKI with 1 µs instruction cycle, two multifunction 16-bit timer/counters, MICROWIRE/PLUSTM serial I/O, one 8-bit/8-channel A/D converter with prescaler and both differential and single ended modes, crystal or R/C oscillator, two power saving HALT/IDLE modes, idle timer, MIWU, high current outputs, software selectable I/O options, WATCHDOGTM timer and Clock Monitor, 2.5V to 6.0V operation and 28/40/44 pin packages.
