25C080T-E/SN

Memory IC Overview

The Microchip Technology 25C080T-E/SN is an 8 Kbit Serial Electrically Erasable PROM featuring a 1024 x 8-bit organization. It operates via a SPI-compatible serial bus with a maximum clock frequency of 3 MHz at VCC levels between 4.5V and 5.5V. The device supports industrial (-40°C to +85°C) and automotive (-40°C to +125°C) temperature ranges, utilizing low-power CMOS technology with typical standby current of 500 nA.

Memory IC Feature Summary

• Supports block write protection for none, one-quarter, one-half, or all array segments
• Includes built-in power-on/off data protection circuitry and a write enable latch
• Features a hold pin to pause serial communication without resetting the sequence

Memory IC Applications

• Microcontroller system data storage
• Industrial control applications
• Automotive electronic systems

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm the voltage range requirements align with the 4.5V to 5.5V specification for the 25C080 variant. Ensure compatibility with existing SPI bus configurations before finalizing procurement decisions.

Memory IC Selection Notes

Select this component when extended temperature operation up to 125°C is required alongside standard 5V logic levels. Compare against the 25LC080 if lower voltage operation down to 2.5V is necessary instead. Consider the 25AA080 for applications requiring operation down to 1.8V.

Memory IC Part Context

This part belongs to the 25XX080 family of 8 Kbit Serial EEPROMs from Microchip Technology. It shares functional similarities with the 25AA080 and 25LC080 but is distinguished by its specific voltage and temperature operating ranges designed for robust industrial and automotive environments.
