25LC080D-E/MS

Overview

The Microchip Technology 25LC080D-E/MS is an 8 Kbit (1024 x 8-bit) Serial Electrically Erasable PROM featuring SPI-compatible interface. It operates within a voltage range of 2.5 V to 5.5 V and supports a maximum clock frequency of 10 MHz at 5.5 V. The device utilizes automotive-grade temperature specifications (-40°C to +125°C) and offers a 32-byte page write capability. Key electrical characteristics include a maximum read current of 5 mA at 5.5 V, standby current of 5 µA, and data retention exceeding 200 years with over 1 million erase/write cycles endurance.

Feature Summary

• Supports high-speed serial communication via standard SPI protocol with hold functionality for bus pausing.
• Includes hardware and software write protection mechanisms with block-level array segmentation options.
• Features built-in power-on/off data protection and self-timed internal write cycle completion.

Applications

• Microcontroller systems requiring non-volatile data storage in automotive environments
• Industrial control applications needing reliable parameter logging
• Consumer electronics utilizing low-power serial memory interfaces

Procurement Notes

Verify the specific suffix 'E' confirms automotive temperature range compliance (-40°C to +125°C) and 'MS' denotes the MSOP-8 package. Confirm RoHS and Pb-free status matches project requirements. Ensure supply chain sources provide valid datasheet references for the 25LC080C/D series to validate electrical parameters against your system constraints.

Selection Notes

Select this component when automotive temperature reliability is required alongside standard SPI EEPROM functionality. The 'D' variant provides 32-byte page writes compared to the 16-byte pages in 'C' variants. Ensure the host microcontroller supports the required SPI modes and voltage levels between 2.5 V and 5.5 V. Consider the MSOP-8 package dimensions for PCB layout constraints.

Part Context

This part belongs to the 25LC080C/D family of 8 Kbit Serial EEPROMs from Microchip Technology. It shares architectural similarities with the 25AA080 series but differs in operating voltage ranges and temperature grades. The 'D' designation indicates 32-byte page size, while 'E' specifies automotive grade performance. It complements other Microchip memory solutions for embedded data storage needs.

Replacement Considerations

25LC080C-E/MS offers identical pinout and functionality but with industrial temperature range (-40°C to +85°C) and 16-byte page size. 25LC080D-I/MS provides the same automotive voltage range but with industrial temperature limits. Verify package compatibility and temperature specifications before substitution.
