Overview
The COP8SGE744V8 is an 8-bit CMOS microcontroller from the COP8SG family, featuring 8k OTP EPROM and 256 bytes of RAM. It utilizes a modified Harvard architecture with a 0.67 μs instruction cycle at 15 MHz CKI. The device integrates two analog comparators, a full-duplex USART, three 16-bit timers, and MICROWIRE/PLUS serial interface. It operates within a 2.7V to 5.5V supply range and supports HALT and IDLE power-saving modes. Available in 44-pin PLCC packages, it includes EMI reduction circuitry and user-selectable clock options.
Feature Summary
- Integrated analog comparators and full-duplex USART for sensor interfacing and communication
- EMI reduction technology including low radiated emissions and gradual turn-on output drivers
- Flexible I/O configuration with software-selectable TRI-STATE, push-pull, and weak pull-up modes
- Multi-function 16-bit timer/counters supporting PWM and external event counting
Applications
- Complex embedded control systems requiring larger memory capacity
- Applications demanding low electromagnetic interference (EMI)
- Sensor interface circuits utilizing onboard analog comparators
- Battery-powered devices leveraging HALT and IDLE power modes
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature range. Ensure compatibility with existing development tools for OTP programming. Confirm availability status as legacy components may have limited production runs or obsolescence notices.
Selection Notes
Select this component for designs requiring form-fit-function compatibility with COP8SGx5 ROM versions. Consider the OTP nature for production flexibility versus fixed ROM costs. Evaluate the 8k memory limit against application code size requirements. Verify that the 44-pin PLCC package fits the board layout constraints.
Part Context
This part belongs to the COP8SG family of 8-bit microcontrollers designed for high integration and low cost. It shares architectural similarities with other COP8 variants but offers specific memory configurations. The family emphasizes code efficiency through a unique instruction set optimized for single-byte execution.
Replacement Considerations
COP8SGR744V8 is a 32k OTP version within the same family. COP8SGE544V8 is the 8k ROM equivalent. Verify pinout and software compatibility when substituting between ROM and OTP variants.
