COP8SAC720M8/NOPB

Overview

The COP8SAC720M8/NOPB is an 8-bit CMOS microcontroller from the COP8SA family, featuring 4k bytes of One-Time Programmable (OTP) memory and 128 bytes of RAM. It utilizes a modified Harvard architecture with a single-cycle instruction cycle time. The device supports a supply voltage range of 2.7V to 5.5V and operates within a temperature range of -40°C to +85°C. It includes a 16-bit timer/counter, MICROWIRE/PLUS serial interface, and Multi-Input Wakeup logic.

Feature Summary

• Integrated low electromagnetic interference (EMI) design utilizing gradual turn-on output drivers and internal current smoothing filters.
• Versatile instruction set optimized for code efficiency, supporting single-byte single-cycle execution and true bit manipulation.
• Flexible I/O configuration allowing software-selectable TRI-STATE, push-pull, or weak pull-up modes with Schmitt trigger inputs on specific ports.

Applications

• Low-cost embedded control systems requiring minimal external components
• Battery-operated devices utilizing power-saving HALT and IDLE modes
• Industrial controllers needing robust EMI performance

Procurement Notes

Verify the component status as this part number may be discontinued or subject to limited availability. Confirm that the OTP programming requirements align with your manufacturing capabilities, as these devices are not reprogrammable after fabrication. Ensure the package type matches your PCB footprint specifications before finalizing procurement orders.

Selection Notes

Select this device when a cost-effective 8-bit solution with integrated EMI reduction is required. It serves as a pin-compatible replacement for older COP800 family devices in new designs. Consider the 4k memory capacity and 128-byte RAM size against application complexity. Verify that the -40°C to +85°C industrial temperature range meets environmental constraints.

Part Context

This component belongs to the COP8SA family of 8-bit microcontrollers manufactured by Texas Instruments (formerly National Semiconductor). The family encompasses ROM-based and OTP variants with memory sizes ranging from 1k to 4k bytes. These devices are designed for high integration and low power consumption in compact packaging solutions.

Replacement Considerations

COP8SAx devices are instruction set and pin compatible supersets of the COP800 Family devices. They serve as direct replacements for COP800 series components in new designs where possible. Verify pinout compatibility if migrating from legacy COP800 parts.
