COP688FH Datasheet | National Semiconductor

Description The COP87L88GD/RD OTP (One Time Programmable) Family microcontrollers are highly integratet COP8™ Feature core devices with 16k or 32k 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. Pin and software patible 16k ROM versions are available (COP888GD), as well as a range of COP8 software and hardware development tools. Device COP87L88GD COP87L88RD Memory (bytes) 16k EPROM 32k EPROM Family features include an 8-bit memory mapped architecture, 10 MHz CKI (-XE = crystal oscillator) with 1µs instruction cycle, three 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, MIWU, idle timer, high current outputs, software selectable I/O options, WATCHDOG™ timer and Clock Monitor, 2.7V to 5.5V operation, program code security, and 44 pin package.
