COP8SAC728N8/NOPB

Overview

The COP8SAC728N8/NOPB is an 8-bit CMOS microcontroller from the COP8SA family, featuring 4k EPROM memory and 128 bytes of RAM. It utilizes a 28-pin DIP package and supports an operating voltage range of 2.7V to 5.5V with a temperature range of -40°C to +85°C. The device includes a 16-bit timer/counter, MICROWIRE/PLUS serial interface, and Multi-Input Wakeup logic.

Feature Summary

Low electromagnetic interference design with gradual turn-on output drivers
Versatile instruction set optimized for code efficiency and program memory utilization
Software-configurable I/O ports supporting multiple drive modes
Integrated power management features including HALT and IDLE modes

Applications

Battery-powered consumer electronics requiring low current drain
Industrial control systems needing robust EMI performance
Cost-sensitive embedded applications utilizing OTP or ROM programming

Procurement Notes

Verify the specific suffix configuration against the manufacturer's ordering guide to ensure correct memory type and package selection. Confirm that the NOPB suffix aligns with current environmental compliance requirements for your target market. Check for end-of-life status as this component belongs to an older generation of microcontrollers.

Selection Notes

Select this part when a modified Harvard architecture with direct data table access from program memory is required. Consider the COP8SA family for designs needing high pin efficiency and flexible I/O configurations. Ensure the application benefits from the single-cycle execution speed and built-in watchdog timer capabilities.

Part Context

This component is part of the COP8SA family, which serves as a superserset replacement for the legacy COP800 devices in new designs. The family emphasizes low cost and small packaging options while maintaining compatibility with existing development tools. It represents a transition point in Texas Instruments' 8-bit microcontroller portfolio.
