COP87L20CJ Datasheet | National Semiconductor

Description The COP87Lxx CJ/RJ Family OTP (One Time Programmable) microcontrollers are integrated COP8™ Base core devices with 4k or 32k memory, and an Analog parator (no brownout). These multi-chip CMOS devices are suited for lower-functionality applications, and as pre-production devices for a ROM design. Low cost, pin and software patible (plus Brownout) 1k or 2k ROM versions are available (COP820CJ/840CJ Family). Versions are available for use with a range of COP8 software and hardware development tools. Family Features include an 8-bit memory mapped architecture, 10 MHz CKI with 1µs instruction cycle, three clock op Device COP87L20CJ COP87L22CJ COP87L40CJ COP87L42CJ COP87L40RJ COP87L42RJ Memory (bytes) 4k OTP EPROM 4k OTP EPROM 4k OTP EPROM 4k OTP EPROM 32k OTP EPROM 32k OTP EPROM RAM (bytes) 64 64 128 128 128 128 tions (-1 = crystal; -2 = external; -3 = internal RC), one multifunction 16-bit timer/counter, MICROWIRE/PLUS™ serial I/O, one analog parator, power saving HALT mode with multi-sourced wakeup/interrupt capability, on-chip R/C oscillator capacitor, high current outputs, software selectable I/O options, WATCHDOG™ timer, modulator/timer, Power on Reset, program code security, 2.7V to 5.5V operation and 20/28 pin packages.
