25LC080AT-I/MS EEPROM Memory IC Equivalent & Substitute Parts

Part Overview

The 25LC080AT-I/MS is an 8Kbit Serial Peripheral Interface (SPI) EEPROM memory IC manufactured by Microchip Technology. This non-volatile memory device operates at 10 MHz clock frequency with a supply voltage range of 2.5V to 5.5V and is housed in an 8-MSOP surface mount package. The part is currently active in production status with ROHS3 compliance and unlimited moisture sensitivity level rating. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the allowed parameter set for this memory IC category.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 25LC080AT-I/MS is determined by strict equivalence across the following critical parameters: memory size (8Kbit), memory organization (1K x 8), interface protocol (SPI), and physical package compatibility (8-MSOP surface mount). All substitute parts must maintain the same non-volatile EEPROM technology and support the required supply voltage range and operating temperature specifications. Clock frequency may exceed the minimum 10 MHz requirement without affecting functional compatibility. Write cycle time specifications of 5ms or faster are acceptable. Packaging format variations (Tape & Reel, Cut Tape, Tube) do not affect electrical substitutability but may impact procurement and assembly workflows.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active production status and ROHS3 compliance. The 25LC080A-I/MS, 25AA080AT-I/MS, and 25AA080CT-I/MS are direct Microchip Technology alternatives with verified or active status. The 25AA080 series parts offer extended supply voltage range (1.8V minimum) compared to the 25LC080 series (2.5V minimum), providing broader compatibility in low-voltage applications. The 25LC080AT-E/MS extends operating temperature range to 125°C, suitable for industrial and automotive temperature environments. The BR25H080FVM-2CTR from Rohm Semiconductor includes AEC-Q100 automotive qualification and achieves faster write cycle time (4ms), with extended temperature range to 125°C. The M95080-WDW6TP from STMicroelectronics operates at 20 MHz clock frequency, exceeding the 10 MHz requirement, and is verified for DiGi-Electronics programming. Package format differences (8-TSSOP versus 8-MSOP) require PCB layout verification for physical fit.

Frequently Asked Questions (FAQ)

Q: Can 25AA080AT-I/MS replace 25LC080AT-I/MS in all applications? A: Yes, provided the application supply voltage does not fall below 1.8V. The 25AA080AT-I/MS supports extended low-voltage operation (1.8V minimum) compared to 25LC080AT-I/MS (2.5V minimum), making it compatible with all 2.5V and higher supply designs.

Q: What is the difference between packaging formats (Tape & Reel, Cut Tape, Tube)? A: Packaging format affects procurement quantity, storage, and assembly automation compatibility. Electrical and mechanical specifications remain identical. Tape & Reel format is optimized for high-volume automated assembly. Cut Tape and Tube formats support lower-volume or manual assembly workflows.

Q: Is M95080-WDW6TP compatible with 25LC080AT-I/MS designs? A: Electrical compatibility is maintained. However, the M95080-WDW6TP uses 8-TSSOP package (0.173" width) versus 25LC080AT-I/MS 8-MSOP package (0.118" width). PCB footprint verification is required before substitution.

Q: Can 25LC080AT-E/MS be used in place of 25LC080AT-I/MS? A: Yes. The 25LC080AT-E/MS is electrically and mechanically identical with extended operating temperature range (-40°C to 125°C versus -40°C to 85°C). It is suitable for applications requiring higher temperature operation.

Q: Does BR25H080FVM-2CTR automotive qualification affect standard industrial applications? A: No. AEC-Q100 qualification indicates enhanced reliability testing and is suitable for both automotive and industrial applications. The part is fully compatible with standard industrial designs.

Q: What clock frequency considerations apply when selecting substitutes? A: The 25LC080AT-I/MS operates at 10 MHz minimum. Substitute parts with equal or higher clock frequency (10 MHz, 20 MHz) are compatible. Higher clock frequency does not affect backward compatibility in designs using lower SPI clock rates.
