25C080-E/SN

Memory IC Overview

The Microchip Technology 25C080-E/SN is an 8 Kbit (1024 x 8) Serial Electrically Erasable PROM featuring SPI-compatible interface. It operates within a VCC range of 4.5V to 5.5V with a maximum clock frequency of 3 MHz. The device supports automotive temperature ranges from -40°C to +125°C and is housed in an 8-lead SOIC package.

Memory IC Feature Summary

• Integrated hardware write protection via dedicated pin and status register bits
• Self-timed erase and write cycles with internal voltage generation
• High endurance rating of 1 million program/erase cycles
• Data retention capability exceeding 200 years

Memory IC Applications

• Automotive electronic control unit data logging
• Industrial sensor calibration storage
• Microcontroller configuration parameter retention

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended automotive temperature grade (-40°C to +125°C). Confirm the 'SN' suffix indicates the narrow SOIC package. Ensure design compliance with the 4.5V minimum supply requirement, as this variant does not support lower voltage operation compared to other family members.

Memory IC Selection Notes

Select this component for applications requiring robust automotive-grade reliability and high-temperature operation. Note that this part is designated as Not Recommended for New Designs; consider newer alternatives like the 25AA080A/B or 25LC080A/B series for future projects while maintaining compatibility with existing designs.

Memory IC Part Context

This device belongs to the 25XX080 family of 8 Kbit serial EEPROMs. It shares architectural similarities with the 25AA080 and 25LC080 but is distinguished by its stricter voltage requirements and extended temperature range suitable for automotive environments.
