COP8SAC720N8

Overview

The COP8SAC720N8 is an 8-bit CMOS One-Time Programmable (OTP) microcontroller from the COP8SA family, manufactured by Texas Instruments. It features 4k bytes of OTP program memory and 128 bytes of RAM. The device operates within a voltage range of 2.7V to 5.5V and supports industrial temperature ranges including -40°C to +85°C. It utilizes a 20-pin DIP package and includes an on-chip R/C oscillator, power-on reset, and low EMI circuitry.

Feature Summary

• Integrated low electromagnetic interference (EMI) design with gradual turn-on output drivers
• Versatile instruction set optimized for code efficiency and single-cycle execution
• Configurable I/O ports supporting push-pull, tri-state, and weak pull-up modes
• Built-in peripherals including a 16-bit timer/counter and MICROWIRE/PLUS serial interface

Applications

• Low-cost embedded control systems requiring small form factors
• Battery-operated devices utilizing low current drain and power-saving modes
• Industrial controllers needing robust EMI performance and high-current outputs
• Consumer electronics applications compatible with MICROWIRE/PLUS interfaces

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to confirm pin compatibility and memory configuration. Ensure that the OTP nature of the device aligns with production requirements, as programming is irreversible. Confirm package type and temperature rating match the intended application environment before finalizing procurement decisions.

Selection Notes

Select this component when a cost-effective 8-bit solution with OTP flexibility is required. Consider the COP8SA family for its modified Harvard architecture allowing direct data table access from program memory. Evaluate the available I/O configurations and interrupt sources to ensure sufficient peripheral support for the target system design without external logic.

Part Context

This part belongs to the COP8SA family of 8-bit microcontrollers, which are supersets of the earlier COP800 family. These devices offer instruction set and pin compatibility with legacy designs while providing enhanced features such as reduced EMI and smaller packaging options. The family supports various memory sizes and packages to accommodate diverse embedded control needs.

Replacement Considerations

COP8SAx devices are designed as replacements for COP800 Family devices in new designs where possible. Verify pin-for-pin compatibility and software migration requirements when substituting older COP800 parts. Consult the official datasheet for detailed architectural differences and timing specifications.
