COP8AME9EMW8/NOPB

Overview

The COP8AME9EMW8/NOPB is an 8-bit CMOS Flash microcontroller from the National Semiconductor COP8 family, manufactured by Texas Instruments. It features 8 kB of program memory and includes integrated dual operational amplifiers, a virtual EEPROM, a temperature sensor, and a 10-bit analog-to-digital converter (ADC). The device incorporates brownout reset functionality for system stability. It operates within a voltage range of 2.7 V to 5.5 V and supports standard communication interfaces including I2C, SMBus, and SPI. The component is housed in a 28-pin SOIC package.

Feature Summary

• Integrates dual operational amplifiers and a 10-bit ADC for analog signal processing capabilities.
• Includes virtual EEPROM for non-volatile data storage without external components.
• Features an on-chip temperature sensor for environmental monitoring.
• Provides brownout reset protection to ensure reliable operation during power fluctuations.

Applications

• Battery-powered devices requiring low-power analog sensing
• Temperature monitoring systems with integrated control logic
• Consumer electronics utilizing virtual EEPROM for configuration storage
• Industrial controllers needing analog input processing via built-in op amps

Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor's embedded processor business. Confirm the specific suffix /NOPB indicates lead-free compliance. Check current availability status as older COP8 series components may be discontinued or subject to long-lead times. Ensure the SOIC-28 package matches your PCB footprint requirements before ordering.

Selection Notes

Select this component when an 8-bit MCU requires integrated analog front-end capabilities such as dual op amps and a 10-bit ADC. It is suitable for applications needing virtual EEPROM to reduce bill-of-materials complexity. Consider the 2.7 V to 5.5 V operating range for compatibility with single-supply systems. Evaluate the 8 kB Flash memory size against application code requirements.
