DescriptionThe COP87LxxCJ/RJ Family OTP (One Time Programmable) microcontrollers are integrated COP8™ Base core devices with 4k or 32k memory, and an Analog comparator (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 compatible (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 of COP87LxxRJ include an 8-bit memory mapped architecture, 10 MHz CKI with 1s instruction cycle, three clock options (-1 = crystal; -2 = external; -3 = internal RC), one multifunction 16-bit timer/counter, MICROWIRE/PLUS™ serial I/O, one analog comparator, 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.
In this datasheet, the term COP87L20CJ refers to the COP87L20CJ, and COP87L22CJ. COP840CJ refers to the COP87L40CJ, COP87L42CJ, COP87L40RJ, and COP87L42RJ.
