COP87L88RW Datasheet | National Semiconductor

Description The COP87L88RW OTP microcontrollers are large memory (32k), highly integrated COP8™ Feature core devices, with advanced features including including Pulse Train Generators, Capture Modules, and hardware multiply/divide. These multi-chip CMOS devices are suited for applications requiring a full featured controller with high I/O pincount, pulse generation and capture, and a full-duplex USART, and for pre-production devices for ROM designs. Pin and software patible 16k ROM versions are available (COP888GW), along with a range of COP8 software and hardware development tools. RAM (bytes) 512 Family features include an 8-bit memory mapped architecture, 10MHz CKI with 1µs instruction cycle, hardware multiply/divide functions, two 100ns capture modules, four pulse train generators with 16 bit prescalers, two multifunction 16-bit timer/counters, idle timer, full-duplex USART, MICROWIRE/PLUS™ serial I/O, two power saving HALT/ IDLE modes, MIWU, high current outputs, software selectable I/O options, 2.7v-5.5v operation, program code security, and 68 pin packages.
