8-Bit CMOS ROM Based Microcontrollers With 1k Or 2k Memory, Comparator And Brown Out Detector
The COP820CJ 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.
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.
