COP87LxxCJ/RJ Family 8-Bit CMOS OTP Microcontrollers with 4k or 32k Memory and Comparator
The COP87LxxCJ/RJ Family consists of integrated COP8 Base core devices available with either 4k or 32k OTP EPROM memory and includes an analog comparator without brownout. These low-cost CMOS microcontrollers are designed for lower-functionality applications and serve as pre-production devices for ROM designs, offering pin and software compatibility with other COP8 family members.
Key features include an 8-bit memory-mapped architecture operating at up to 10 MHz, a multi-function 16-bit timer/counter, MICROWIRE/PLUS serial I/O, and a watchdog timer. The devices support three clock options (crystal, external, or internal R/C oscillator) and operate with a single supply voltage ranging from 2.7V to 5.5V in 20 or 28-pin DIP/SOIC packages.
| RAM Size | 64 or 128 bytes |
|---|---|
| Operating Voltage | 2.7V to 5.5V |
| Instruction Cycle Time | 1 µs (at 10 MHz) |
| Temperature Range | -40°C to +85°C |
| Packages | 20 or 28 pin DIP/SOIC |
These devices are suited for lower-functionality applications and as pre-production devices for a ROM design.
There are three clock options: crystal (-1), external oscillator (-2), and internal R/C oscillator (-3).
