COP8CDR9LVA8

Overview

The COP8CDR9LVA8 is an 8-bit CMOS Flash microcontroller from the National Semiconductor COP8 series. It features 32KB (32K x 8) of FLASH memory and operates at a maximum clock frequency of 20MHz. The device is housed in a 68-pin PLCC package measuring 25.13x25.13 mm. It integrates virtual EEPROM, a 10-bit analog-to-digital converter, and brownout detection capabilities.

Feature Summary

• Integrated 32KB FLASH memory for program storage
• Built-in virtual EEPROM functionality
• Includes 10-bit analog-to-digital conversion
• Features brownout detection circuitry

Applications

• General-purpose embedded control systems
• Industrial automation controllers
• Consumer electronics devices requiring analog input processing

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm package integrity and pin alignment upon receipt. Check for obsolescence status as National Semiconductor assets are managed by Texas Instruments. Ensure environmental compliance documentation matches specific project requirements before final procurement decisions.

Selection Notes

Select this component when an 8-bit architecture with substantial on-chip FLASH is required. The 68-PLCC package suits applications needing high I/O density. Consider the 20MHz operational speed for real-time processing tasks. Evaluate the integrated ADC and virtual EEPROM to reduce external component count in system designs.

Part Context

This microcontroller belongs to the COP8 family, known for robust 8-bit performance. National Semiconductor was acquired by Texas Instruments, which now manages the product line. The COP8 series is widely used in cost-sensitive embedded applications requiring reliable flash-based programming and integrated peripheral functions.

Replacement Considerations

Consult official Texas Instruments documentation for verified cross-references. The COP8CDR9LVA7 shares similar specifications but may differ in minor revisions. Verify pin compatibility and software compatibility before substituting any alternative part numbers.
