COP8SGE740N8

Overview

The COP8SGE740N8 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 15 MHz clock input and supports instruction cycle times as fast as 0.67 μs. The device includes two analog comparators, a full-duplex USART, three 16-bit timers, and MICROWIRE/PLUS serial interface capabilities. It operates within a voltage range of 2.7V to 5.5V and is available in 44-pin PLCC packages.

Feature Summary

• Integrated EMI reduction circuitry including low radiated emissions design and gradual turn-on output drivers.
• Versatile I/O configuration allowing software-selectable modes such as TRI-STATE, push-pull, and weak pull-up inputs.
• Advanced power management features including HALT and IDLE modes for significant current drain reduction.
• High code efficiency through a unique instruction set optimized for single-byte and single-cycle execution.

Applications

• Complex embedded control systems requiring larger memory capacity
• Applications demanding low electromagnetic interference (EMI)
• Systems utilizing analog signal processing via integrated comparators
• Industrial controllers needing robust serial communication interfaces

Procurement Notes

Verify the specific package variant and temperature rating during procurement, as the COP8SG family encompasses multiple pin configurations and operating ranges. Confirm that the OTP version aligns with production or development needs, noting that windowed versions are distinct. Ensure compatibility with existing development tools if erasable variants were previously utilized in the design.

Selection Notes

Select this component when system requirements necessitate high integration with minimal external components. The COP8SGE7 offers form-fit-function compatibility with ROM-based COP8SGx5 devices, facilitating direct upgrades. Consider the 44-pin package density for maximizing I/O availability while minimizing board space usage in compact designs.

Part Context

This part belongs to the COP8SG family of 8-bit microcontrollers designed for complex applications. It serves as the OTP counterpart to the mask-programmed ROM versions, providing identical functionality for production deployment. The family emphasizes cost-effectiveness and performance through its specialized instruction set and peripheral integration.

Replacement Considerations

COP8SGR7 is a compatible OTP alternative within the same family offering higher memory capacity. For ROM-based replacements, COP8SGE5 provides equivalent functionality with fixed program storage. Verify pinout and memory size requirements before substituting.
