DescriptionThe COP820CJ/840CJ Family ROM based microcontrollers are integrated COP8™ Base core devices with 1k or 2k memory, an Analog comparator and Brownout detection. These single-chip CMOS devices are suited for lower-functionality applications where power and voltage fluctuations are a consideration. Pin and software compatible (no Brownout; different Vcc range) 4k/32k OTP versions are available (COP87LxxCJ/RJ Family) for pre-production, and for use with a range of COP8 software and hardware development tools.
COP840CJ Family features include an 8-bit memory mapped architecture, 10MHz CKI with 1us instruction cycle, one multi-function 16-bit timer/counter, MICROWIRE/PLUS™ serial I/O, one analog comparator, 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.

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.For more information on Reliability Metrics, please click here.
