The 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. The 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, WATCH- DOG™ timer, modulator/timer, Brownout detector, Power on Reset, 2.5v-6.0v operation, and 16/20/28 pin packages.
This document describes the COP820CJ/COP840CJ Family ROM-based microcontrollers, which are single-chip CMOS devices designed for lower-functionality applications where power consumption and voltage fluctuations are critical considerations. The family includes devices with 1k or 2k memory, an analog comparator, a Brownout detector, and a watchdog timer.
