25LC080A-E/MS

Overview

The Microchip Technology 25LC080A-E/MS is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It utilizes a standard SPI-compatible serial bus with a maximum clock frequency of 10 MHz and a typical access time of 50 ns. The device operates within a supply voltage range of 2.5 V to 5.5 V and supports automotive temperature ranges from -40°C to +125°C. It is housed in an 8-lead MSOP package.

Feature Summary

• Supports block write protection allowing selective array segment locking
• Includes built-in power-on/off data protection circuitry
• Features a hold pin for pausing serial communication without sequence reset

Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value logging

Procurement Notes

Verify the specific suffix 'E' confirms the automotive temperature grade (-40°C to +125°C) and 'MS' denotes the 8-lead MSOP package. Confirm RoHS compliance status as required by your manufacturing standards. Check current lifecycle status, as this part may be subject to change or discontinuation.

Selection Notes

Select this component when an SPI interface is required for non-volatile memory with automotive-grade temperature resilience. Ensure the 2.5 V minimum supply voltage aligns with your system's logic levels. Consider page size limitations during write operations to prevent data wrap-around across physical boundaries.

Part Context

This EEPROM belongs to the 25XX080A/B family, which includes variants like the 25AA080A. The 'LC' designation indicates a 2.5 V minimum operating voltage, distinguishing it from the 'AA' series which supports lower voltages down to 1.8 V. All members share identical pinouts and instruction sets.

Replacement Considerations
