COP8ACC728M9-XE

Overview

The COP8ACC728M9-XE is an 8-bit microcontroller from the National Semiconductor COP8™ 8A series. It features a 4MHz operating frequency and includes 4KB (4K x 8) of One-Time Programmable (OTP) memory. The device is housed in a 28-SOIC package and utilizes CMOS technology. It integrates a 6-channel, 12-bit A/D converter for analog signal processing capabilities within embedded applications.

Feature Summary

• Integrates a high-resolution 6-channel, 12-bit analog-to-digital converter for precise sensor interfacing.
• Utilizes OTP memory architecture to provide non-volatile program storage with single-time configuration capability.
• Employs CMOS technology to support efficient power consumption profiles in compact surface-mount packages.

Applications

• Embedded control systems requiring analog input monitoring
• Battery-powered devices utilizing low-power CMOS architectures
• Industrial automation components needing integrated ADC functionality

Procurement Notes

Verify the specific suffix designation against official National Semiconductor documentation to confirm pinout compatibility and electrical characteristics. Ensure that the OTP nature of the memory aligns with the project's firmware update requirements, as reprogramming is not possible after initial fabrication. Cross-reference the 28-SOIC package dimensions with PCB layout specifications to ensure mechanical fit.

Selection Notes

Select this component when an integrated 12-bit ADC is required alongside an 8-bit processing core in a single IC. The COP8 architecture suits applications where fixed-function peripherals reduce external component count. Consider the OTP constraint for production volumes where firmware changes are unlikely post-manufacturing. Evaluate the 4MHz speed against real-time processing demands.

Part Context

This part belongs to the COP8 family, known for integrating standard microcontroller functions with specialized analog peripherals. The COP8™ 8A series specifically targets cost-sensitive applications requiring moderate performance and integrated analog capabilities without external support chips.

Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the COP8ACC728 series. Verify memory size and ADC channel counts match exactly before substituting.
