25AA010AT-I/MC

Memory IC Overview

The Microchip Technology 25AA010AT-I/MC is a 1 Kbit Serial Electrically Erasable Programmable Read-Only Memory (EEPROM) utilizing a 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 2x3 DFN package with exposed pad. It includes self-timed erase and write cycles with a maximum duration of 5 ms.

Memory IC Feature Summary

• Supports sequential read operations and page write mode for up to 16 bytes per cycle.
• Includes built-in hardware write protection via the WP pin and software block protection for array segments.
• Features a HOLD input to pause serial communication without resetting the sequence, allowing host interrupt servicing.

Memory IC Applications

• Microcontroller system configuration storage
• Calibration parameter persistence
• Data logging buffer memory

Memory IC Procurement Notes

Verify the specific suffix 'I/MC' corresponds to the Industrial temperature grade (-40°C to +85°C) and the 8-DFN (2x3) package type. Confirm RoHS compliance status matches current manufacturing standards. Ensure the ordering code aligns with the required tape and reel quantity if automated assembly is planned.

Memory IC Selection Notes

Select this component when a low-pin-count non-volatile memory solution is required for small data sets. The 1.8V minimum operating voltage makes it suitable for battery-powered or low-voltage logic systems. The industrial temperature range ensures reliability in standard commercial environments where extreme thermal conditions are not expected.

Memory IC Part Context

This part belongs to the 25AA010A family of 1 Kbit SPI EEPROMs from Microchip Technology. It shares functional compatibility with the 25LC010A series, differing primarily in the lower minimum supply voltage requirement of 1.8V compared to 2.5V. The 'T' indicates a tape and reel packaging format.

Memory IC Replacement Considerations

The 25LC010AT-I/MC is a direct functional substitute with identical pinout and instruction set, though it requires a higher minimum supply voltage of 2.5V. Other 25AA010 variants with different packages (e.g., SOIC, MSOP) may be used if board space allows.
