25LC080C-E/MS

Overview

The Microchip Technology 25LC080C-E/MS is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM accessed via a SPI-compatible bus. It operates within a voltage range of 2.5V to 5.5V and supports a maximum clock frequency of 10 MHz at 5.5V. The device features a 16-byte page size, self-timed write cycles up to 5 ms, and automotive temperature ratings from -40°C to +125°C. Key electrical characteristics include a standby current of 5 µA and read/write currents of 5 mA. It offers high reliability with over 1 million erase/write cycles and data retention exceeding 200 years.

Feature Summary

• Supports serial communication via standard SPI interface with hold functionality for interrupt servicing
• Includes programmable block write protection and hardware write-protect pin capabilities
• Features built-in power-on/off data protection and write enable latch mechanisms

Applications

• Automotive embedded systems requiring extended temperature operation
• Industrial control applications needing non-volatile configuration storage
• Consumer electronics utilizing low-power serial memory interfaces

Procurement Notes

Verify the specific 'E' suffix indicates automotive grade qualification (-40°C to +125°C) rather than industrial grade. Confirm the 'C' designation corresponds to the 16-byte page size variant. Ensure the MSOP package matches your PCB footprint requirements. Check for RoHS compliance status as per the latest datasheet revision.

Selection Notes

Select this component when automotive temperature ranges are required alongside standard SPI compatibility. Compare against the 25LC080D variant if a larger 32-byte page size is preferred for throughput. Consider the 25AA080C series if lower voltage operation down to 1.8V is necessary for the system design.

Part Context

This part belongs to the 25LC080C/D family of 8K SPI Serial EEPROMs. The 'C' version specifically utilizes a 16-byte page buffer, distinguishing it from the 'D' version which uses 32 bytes. The 'E' suffix denotes automotive grade reliability and extended temperature performance compared to the standard industrial 'I' grade variants.
