COP942CJ Datasheet | National Semiconductor

Description The COP820CJ/840CJ Family ROM based microcontrollers are integrated COP8™ Base core devices with 1k or 2k memory, an Analog parator and Brownout detection. These single-chip CMOS devices are suited for lowerfunctionality applications where power and voltage fluctuations are a consideration. Pin and software patible (no Brownout; different Vcc range) 4k/32k OTP versions are available (COP87Lxx CJ/RJ Family) for pre-production, and for use with a range of COP8 software and hardware development tools. Family features include an 8-bit memory mapped architecture, 10MHz CKI with 1us instruction cycle, one multifunction 16-bit timer/counter, MICROWIRE/PLUS™ serial I/O, one analog parator, power saving HALT mode, MIWU, on-chip R/C oscillator capacitor (COP840CJ), high current outputs, software selectable I/O options, WATCHDOG™ timer, modulator/timer, Brownout detector, Power on Reset, 2.5v-6.0v operation, and 16/20/28 pin packages. In this datasheet, the term COP820CJ refers to packages including the COP820CJ, COP822CJ, and COP823CJ; and COP840CJ refers to COP840CJ, COP842CJ, COP940CJ, and COP942CJ.
