COP8SGE728M8

Overview

The COP8SGE728M8 is an 8-bit CMOS microcontroller from the COP8SG family, featuring 8k ROM and 256 bytes of RAM. It utilizes a modified Harvard architecture with a 0.67 μs instruction cycle time at 15 MHz CKI. The device includes three 16-bit timers, a full-duplex USART, MICROWIRE/PLUS serial interface, and two analog comparators. Operating voltage ranges from 2.7V to 5.5V, with temperature ratings of -40°C to +85°C or -40°C to +125°C depending on the specific suffix.

Feature Summary

• Integrated EMI reduction circuitry including low radiated emissions clocking and gradual turn-on output drivers.
• Versatile I/O configuration allowing software-selectable TRI-STATE, push-pull, weak pull-up, and high impedance modes.
• Multi-input wakeup logic supporting eight pins with optional interrupts for power-saving HALT and IDLE modes.

Applications

• Complex embedded control systems requiring low electromagnetic interference.
• Applications utilizing full-duplex serial communication via USART.
• Systems integrating analog signal processing through onboard comparators.
• Battery-powered devices benefiting from low current drain and multiple power-saving modes.

Procurement Notes

Verify the exact ordering suffix against the manufacturer's datasheet to confirm memory type (ROM vs OTP), package style, and temperature range. Ensure compatibility with existing development tools such as iceMASTER emulators if hardware debugging is required. Confirm that the selected variant meets the specific environmental operating conditions of the target application.

Selection Notes

Select this component when a cost-effective 8-bit solution with integrated analog features is needed. The COP8SGE7 variant serves as the OTP version compatible with the COP8SGE5 ROM counterpart. Consider the pin count and package options available in the family to match board space constraints while ensuring sufficient I/O availability for system requirements.

Part Context

This device belongs to the COP8SG family of 8-bit CMOS microcontrollers designed for applications demanding higher integration than standard COP8 devices. The family combines mask-programmable ROM and OTP EPROM options within a unified architecture. It supports various packages including SOIC, PDIP, PLCC, LQFP, and WQFN to accommodate different form factors.

Replacement Considerations

COP8SGE5 variants are functionally compatible ROM-based alternatives. COP8SGR7 offers higher memory capacity within the same family. Windowed versions like COP8SGR7-Q3 are available for development purposes using erasable EPROM technology.
