COP8AME9ENA8

Overview

The COP8AME9ENA8 is an 8-bit CMOS Flash microcontroller from the National Semiconductor COP8 family. It features 8k bytes of program memory and includes integrated analog peripherals such as dual operational amplifiers, a temperature sensor, and a 10-bit analog-to-digital converter (ADC). The device incorporates virtual EEPROM for data storage and provides brownout reset functionality. It utilizes a plastic leaded chip carrier package with 28 pins.

Feature Summary

• Integrated 10-bit analog-to-digital converter for signal acquisition
• Dual on-chip operational amplifiers for analog processing
• Built-in temperature sensor for thermal monitoring
• Virtual EEPROM capability for non-volatile data retention

Applications

• Battery-powered devices requiring low power consumption
• Temperature sensing and control systems
• Consumer appliances with analog input requirements
• Industrial controllers utilizing onboard op-amps

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment against the PLCC-28 specification. Ensure compliance with relevant environmental standards prior to integration into final assemblies.

Selection Notes

Select this component when an 8-bit architecture suffices for control logic alongside integrated analog functions. The inclusion of dual op-amps and a 10-bit ADC reduces external component count. Consider the 8k memory limit for application complexity and verify voltage operating ranges match system requirements.

Part Context

This part belongs to the COP8AME9 series, designed for applications needing mixed-signal capabilities within an 8-bit MCU framework. It shares architectural similarities with other COP8 devices but distinguishes itself through specific analog integrations like the temperature sensor and dual op-amps, targeting cost-sensitive embedded solutions.

Replacement Considerations

Direct substitutes include COP8AME9EMW8 and COP8CFE9. Verify pin compatibility and memory size before substitution. Cross-reference datasheets for any differences in analog peripheral specifications or package dimensions.
