25LC080CT-E/MNY

Overview

The Microchip Technology 25LC080CT-E/MNY 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 levels between 4.5V and 5.5V. The device supports a supply voltage range of 2.5V to 5.5V and utilizes a 16-byte page size architecture. It is housed in an 8-lead TDFN package and is rated for an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Supports high-speed SPI communication with up to 10 MHz clock frequency
• Includes programmable block write protection for array security
• Features built-in power-on/off data protection circuitry
• Provides hold functionality to pause serial transmission without resetting the sequence

Applications

• Microcontroller system data storage
• Industrial control applications requiring extended temperature operation
• Automotive embedded memory solutions
• Portable devices utilizing low-power CMOS technology

Procurement Notes

Verify the specific suffix 'E' confirms the automotive temperature grade (-40°C to +125°C) and 'MNY' denotes the 8-lead TDFN package. Confirm the 'C' variant designation indicates the 16-byte page size structure. Ensure compatibility with the required SPI interface timing parameters for your target operating voltage.

Selection Notes

Select this component when an 8 Kbit non-volatile memory solution is required for environments exceeding standard industrial limits. The automotive grade ensures reliability under higher thermal stress. Consider the TDFN package constraints for PCB layout if space is limited. Verify that the 16-byte page write limitation aligns with your application's data handling logic.

Part Context

This part belongs to the 25LC080C/D family of 8K SPI Bus Serial EEPROMs manufactured by Microchip Technology. The 'C' version specifically designates the 16-byte page buffer configuration, distinguishing it from the 'D' version which offers a 32-byte page size. This family is designed for direct interfacing with popular microcontroller families.

Replacement Considerations

The 25LC080DT-E/MNY serves as a confirmed substitute within the same product family, offering identical electrical characteristics but utilizing a 32-byte page size instead of 16 bytes.
