25AA010AT-I/MNY

Memory IC Overview

The Microchip Technology 25AA010AT-I/MNY is a 1 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) utilizing an SPI-compatible serial bus. It features a 128 x 8-bit organization and supports a maximum clock frequency of 10 MHz. The device operates within a supply voltage range of 1.8V to 5.5V and is housed in an 8-lead TDFN package. It includes write page mode for up to 16 bytes, self-timed erase/write cycles with a maximum duration of 5 ms, and block write protection capabilities.

Memory IC Feature Summary

• Supports high-speed SPI communication with a maximum clock frequency of 10 MHz.
• Includes hardware write protection via the WP pin and software-based block protection for array segments.
• Features a HOLD input to pause serial transmission without resetting the sequence.

Memory IC Applications

• Microcontroller system data storage
• Configuration parameter retention
• Calibration value storage

Memory IC Procurement Notes

Verify that the ordering suffix 'MN' corresponds to the TDFN package type as specified in the datasheet. Confirm the temperature grade 'I' matches industrial requirements (-40°C to +85°C). Ensure the 'T' indicates tape-and-reel packaging if automated assembly is planned. Cross-reference the full part number against the manufacturer's current documentation to confirm availability and compliance status.

Memory IC Selection Notes

Select this component when a low-pin-count EEPROM with SPI interface is required. The 1.8V minimum operating voltage makes it suitable for low-voltage applications compared to the 2.5V minimum of the 25LC010A variant. The TDFN package offers a compact footprint for space-constrained designs. Verify that the 16-byte page size aligns with the application's write granularity needs.

Memory IC Part Context

This part belongs to the 25XX010A family of 1 Kbit SPI EEPROMs from Microchip Technology. It shares functional similarities with the 25LC010A but differs in its lower minimum supply voltage requirement. The family supports various packages including SOIC, MSOP, and DFN, providing flexibility for different board layout constraints while maintaining consistent electrical characteristics across variants.

Memory IC Replacement Considerations

The 25LC010AT-I/MNY is a direct functional substitute with identical specifications except for a higher minimum supply voltage of 2.5V. Other 25AA010A variants with different package suffixes (e.g., SN, MS) are compatible if the physical footprint allows.
