Memory IC datasheet and documents for 25AA640A-E/MS

25AA640A-E/MS

Memory IC Overview

The Microchip Technology 25AA640A-E/MS is a 64-Kbit Serial Electrically Erasable PROM featuring an SPI-compatible interface. It utilizes low-power CMOS technology with a supply voltage range of 1.8V to 5.5V and supports a maximum clock frequency of 10 MHz. The device offers 8192 x 8-bit organization, 32-byte page write capability, and self-timed erase/write cycles up to 5 ms. It provides high reliability with 1,000,000 erase/write cycle endurance, data retention exceeding 200 years, and ESD protection greater than 4000V. The Extended temperature grade (-E) supports operation from -40°C to +125°C in an 8-lead MSOP package.

Memory IC Feature Summary

Supports serial communication via a standard four-wire SPI bus (SCK, SI, SO, CS).
Includes hardware write protection mechanisms such as block protection and power-on/off data protection circuitry.
Features a HOLD pin to suspend transmission without resetting the serial sequence.

Memory IC Applications

Data storage for microcontroller systems requiring non-volatile memory.
Configuration storage in industrial control applications.
Parameter logging in automotive electronic modules.

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance status and ensure the component meets AEC-Q100 qualification requirements if intended for automotive use. Check datasheet revisions for any recent manufacturing changes or packaging updates before finalizing procurement specifications.

Memory IC Selection Notes

Select this part when extended temperature operation up to 125°C is required alongside standard SPI compatibility. Ensure the system design accommodates the 1.8V to 5.5V supply range and 10 MHz clock speed. Consider the 32-byte page size limitation for write operations and verify that the MSOP-8 package fits the available PCB footprint constraints.

Memory IC Part Context

This component belongs to the 25XX640A family of 64-Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 25LC640A but differs in minimum operating voltage specifications. The 'E' suffix denotes the extended temperature range variant, while 'MS' indicates the 8-lead Mini Small Outline Package.
