25AA010AT-I/OT

Memory IC Overview

The Microchip Technology 25AA010AT-I/OT is a 1 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) utilizing a Serial Peripheral Interface (SPI) compatible bus. It features a 128 x 8-bit organization with a maximum clock frequency of 10 MHz and operates within a supply voltage range of 1.8V to 5.5V. The device supports industrial temperature ranges from -40°C to +85°C and is housed in a 6-lead SOT-23 package.

Memory IC Feature Summary

• Supports sequential read operations and page write modes for efficient data handling
• Includes hardware write protection via the WP pin and software block protection capabilities
• Features built-in power-on/off data protection circuitry and a write enable latch

Memory IC Applications

• Microcontroller system configuration storage
• Calibration data retention in embedded devices
• Parameter logging in industrial monitoring equipment

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'OT' indicates the 6-lead SOT-23 package. Confirm RoHS compliance status and ensure the specific datasheet revision matches the required design specifications before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact 6-lead footprint is required for low-pin-count SPI EEPROM applications. Ensure the host microcontroller supports the necessary SPI protocol and voltage levels compatible with the 1.8V to 5.5V operating range. Consider the 16-byte page size limitations for write operations during system architecture planning.

Memory IC Part Context

This part belongs to the 25XX010A family of 1 Kbit serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with other members like the 25LC010A but differs in minimum operating voltage and package availability. The 'A' suffix denotes an updated version of the original 25XX010 series.

Memory IC Replacement Considerations

Direct substitutes include other 1 Kbit SPI EEPROMs from Microchip such as the 25AA010A-I/SN or 25LC010A variants, provided they match the required voltage range and package type. Cross-vendor replacements require verification of pin compatibility and SPI command set alignment.
