The COP820CJ/840CJ Family ROM based microcontrollers are integrated COP8™ Base core devices with 1k or 2k memory, an Analog comparator and Brownout detection.
This document describes the COP820CJ/COP840CJ Family of ROM-based microcontrollers. These single-chip CMOS devices integrate an 8-bit memory-mapped architecture with 1k or 2k bytes of memory, an analog comparator, and a Brownout detector.
The family is designed for lower-functionality applications where power consumption and voltage fluctuations are critical considerations. Key features include a 10MHz clock input, a multi-function timer/counter supporting PWM modes, MICROWIRE/PLUS serial I/O, and software-selectable I/O options.
| Memory (ROM) | 1k or 2k bytes |
|---|---|
| RAM | 64 or 128 bytes |
| Operating Voltage | 2.5V to 6.0V |
| Instruction Cycle Time | 1 us (at 10MHz) |
| Temperature Range | -40 to +85°C |
The instruction cycle time is 1 us when using a 10MHz CKI.
Yes, the devices feature an integrated Brownout detection circuit.
