COP8SGR728M8

Overview

The COP8SGR728M8 is an 8-bit CMOS microcontroller from the COP8SG family, featuring a 32k OTP EPROM and 512 bytes of RAM. It utilizes the COP800 CPU core with a maximum clock frequency of 15 MHz and instruction cycle times as low as 0.67 μs. The device operates within a voltage range of 2.7V to 5.5V and supports temperature ranges of -40°C to +85°C or -40°C to +125°C. It includes two analog comparators, a full-duplex USART, three 16-bit timers, and MICROWIRE/PLUS serial interface capabilities.

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, weak pull-up, and high impedance.
• Supports multiple power-saving HALT and IDLE modes with user-selectable wake-up sources.
• Features a modified Harvard architecture enabling direct access to data tables stored in program memory.

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 communication interfaces

Procurement Notes

Verify the specific suffix codes for package type and temperature grade against the manufacturer's ordering information. Confirm that the OTP programming requirements align with your production development tools. Ensure compatibility with existing COP8SG family hardware designs due to form-fit-function specifications.

Selection Notes

Select this component when a balance of high integration and cost-efficiency is required for 8-bit applications. Consider the OTP variant for prototyping or low-volume production where ROM customization is necessary. Evaluate the available I/O pin count and peripheral features against system requirements before choosing between different memory sizes in the family.

Part Context

This device belongs to the COP8SG family of 8-bit microcontrollers designed by Texas Instruments. The family offers various memory configurations ranging from 8k to 32k and includes both ROM and OTP versions. The R7 designation indicates the 32k OTP EPROM variant within this series.

Replacement Considerations

COP8SGK5 devices are form-fit-function compatible ROM alternatives within the same family. Windowed erasable versions (Q3) are available for development purposes. Verify pinout and electrical specifications when substituting with other COP8SG members.
