25LC080A-E/SN

Overview

The Microchip Technology 25LC080A-E/SN is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM. It features a 16-byte page size and operates within a supply voltage range of 2.5 V to 5.5 V. The device supports a maximum clock frequency of 10 MHz and utilizes a standard SPI-compatible interface. It is housed in an 8-lead MSOP package and is rated for an extended automotive temperature range from -40 °C to +125 °C.

Feature Summary

• Supports high-speed serial communication via a standard SPI bus with up to 10 MHz clock frequency.
• Includes programmable block write protection allowing selective array security.
• Features built-in power-on/off data protection and a write enable latch mechanism.
• Provides a hold function to pause serial transmission without resetting the sequence.

Applications

• Automotive electronic control units requiring extended temperature reliability
• Industrial systems needing persistent configuration storage
• Embedded devices utilizing microcontroller SPI interfaces

Procurement Notes

Verify that the 'E' suffix confirms the automotive grade (-40°C to +125°C) and the 'SN' suffix specifies the 8-lead MSOP package. Ensure the 'A' designation matches the required 16-byte page size, as 'B' versions utilize 32-byte pages. Confirm RoHS compliance status during sourcing.

Selection Notes

Select this component when an 8 Kbit capacity is sufficient for non-volatile data retention. The 2.5 V minimum operating voltage makes it suitable for 3.3 V and 5 V logic systems. The automotive temperature rating is essential for harsh environments where industrial grades may fail.

Part Context

This part belongs to the 25LC080A/B family of 8 Kbit SPI EEPROMs. The 'LC' indicates a 2.5 V to 5.5 V operating range, distinguishing it from the 1.8 V compatible 'AA' series. The 'A' variant specifically defines the 16-byte page architecture used for write operations.

Replacement Considerations

The 25LC080A-B/SN is a direct functional substitute sharing identical specifications and pinouts. Other 25LC080A variants are available in PDIP or TSSOP packages if form factor changes are permissible.
