Memory IC datasheet and documents for 25AA040XT-I/ST

25AA040XT-I/ST

Memory IC Overview

The Microchip Technology 25AA040XT-I/ST is a 4 Kbit (512 x 8-bit) serial Electrically Erasable PROM. It operates within a supply voltage range of 1.8V to 5.5V and supports an industrial temperature range of -40°C to +85°C. The device utilizes a Serial Peripheral Interface (SPI) compatible bus with a maximum clock frequency of 1 MHz. It features a TSSOP-8 package in tape and reel format, ensuring low-power CMOS operation with typical standby current of 500 nA.

Memory IC Feature Summary

Supports hardware write protection via the WP pin and software block protection for selective array segments.
Includes built-in power-on/off data protection circuitry and a self-timed write cycle mechanism.
Enables communication pausing through the HOLD pin without resetting the active serial sequence.

Memory IC Applications

Data logging applications requiring non-volatile storage
Configuration parameter storage in embedded systems
Calibration data retention in industrial sensors

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and delivery method. Confirm the voltage grade corresponds to the system's operating requirements. Ensure the temperature rating aligns with the intended environmental conditions. Cross-reference the datasheet revision to confirm compatibility with existing design specifications.

Memory IC Selection Notes

Select this component when a 4 Kbit capacity is sufficient for the application. Consider the TSSOP-8 package constraints regarding board space and thermal dissipation. Evaluate the SPI interface compatibility with the host microcontroller. Assess the endurance and retention specifications against the expected write cycle frequency.

Memory IC Part Context

This part belongs to the 25XX040 family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 25LC040 and 25C040 variants, differing primarily in supply voltage ranges and temperature grades. The 'XT' suffix indicates a tape and reel packaging configuration with an alternate pinout specific to the TSSOP package.
