COP8SGR744V8/63SN

Overview

The COP8SGR744V8/63SN is an 8-bit CMOS OTP microcontroller from the COP8SG family, housed in a 44-pin PLCC package. It features 32k OTP EPROM memory and 512 bytes of on-board RAM. The device includes two analog comparators, a full-duplex USART, MICROWIRE/PLUS serial interface, three 16-bit timers, and an idle timer. Operating voltage ranges from 2.7V to 5.5V with instruction cycle times as fast as 0.67 μs at 15 MHz. It supports multi-input wakeup logic, software-selectable I/O options, and low current drain HALT and IDLE power-saving modes.

Feature Summary

• Integrated dual analog comparators for signal processing applications
• Full-duplex USART and MICROWIRE/PLUS serial communication interfaces
• Three 16-bit timers supporting PWM, external event counting, and input capture
• Patented EMI reduction technology including gradual turn-on output drivers

Applications

• Complex embedded control systems requiring larger memory capacity
• Applications necessitating analog signal comparison without external components
