25LC080CT-E/SN

Overview

The Microchip Technology 25LC080CT-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 10 MHz at VCC = 5.5V. The device supports a supply voltage range of 2.5V to 5.5V and utilizes a 16-byte page write architecture. It is housed in an 8-lead SOIC package (SN suffix) and is rated for an extended temperature range of -40°C to +125°C.

Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes hardware write protection via WP pin and software block protection
• Features built-in power-on/off data protection circuitry
• Provides hold functionality to pause serial communication without resetting the sequence

Applications

• Microcontroller system data storage
• Industrial control applications requiring wide temperature operation
• Automotive electronics systems
• Embedded devices needing non-volatile parameter retention

Procurement Notes

Verify the specific suffix 'E' confirms the automotive temperature grade (-40°C to +125°C) and 'SN' indicates the 8-lead SOIC package. Confirm the 'CT' suffix matches the required tape and reel packaging format for automated assembly processes. Ensure the device version corresponds to the 'C' variant with 16-byte page size requirements.

Selection Notes

Select this component when an SPI EEPROM requires operation across the full automotive temperature range. The 8Kb capacity suits applications storing configuration data or small datasets. Verify that the 2.5V minimum supply voltage aligns with the system's power rails, as lower voltage variants like the 25AA series are not compatible with this specific part number.

Part Context

This part belongs to the 25LC080C/D family of 8Kbit Serial EEPROMs from Microchip Technology. The 'LC' designation indicates a 2.5V to 5.5V operating voltage range, distinguishing it from the 'AA' series which supports 1.8V. The 'E' suffix denotes the extended temperature grade suitable for harsh environments compared to the standard industrial 'I' grade.
