COP8SGE728M8/NOPB

Overview

The COP8SGE728M8/NOPB is an 8-bit CMOS OTP microcontroller from the COP8SG family. It features 8k OTP EPROM memory and 256 bytes of on-board RAM. The device supports a maximum clock frequency of 15 MHz with a 0.67 μs instruction cycle time. It 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 an industrial temperature range of -40°C to +125°C.

Feature Summary

• Integrated EMI reduction technology including low radiated emissions circuitry 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 input.
• Multi-input wakeup logic supporting eight pins with optional interrupts for power-saving wake-up capabilities.

Applications

• Complex embedded control applications requiring larger memory and advanced peripherals
• Systems demanding low electromagnetic interference (EMI) performance
• Battery-powered devices utilizing HALT and IDLE power saving modes

Procurement Notes

Verify the specific package type and suffix against the official Texas Instruments COP8SG datasheet (SNOS516E). Confirm that the OTP version matches the required development tool compatibility. Ensure the operating temperature range aligns with system specifications before procurement.

Selection Notes

Select this component for designs requiring 8k program memory and 256 bytes of RAM within the COP8SG architecture. Consider the OTP nature for production or final development stages where ROM versions are not suitable. Evaluate the available packages (SOIC, PDIP, PLCC, LQFP, WQFN) based on board space constraints.
