25LC010AT-I/OT

Overview

The Microchip Technology 25LC010AT-I/OT is a 1 Kbit (128 x 8) Serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It operates on an SPI-compatible serial bus with a maximum clock frequency of 10 MHz. The device supports a supply voltage range of 2.5 V to 5.5 V and functions within an industrial temperature range of -40°C to +85°C. It utilizes an 8-lead OT package.

Feature Summary

• Supports write page mode for up to 16 bytes per cycle
• Includes hardware write protection via the WP pin
• Features self-timed erase and write cycles

Applications

• Configuration data storage in microcontroller systems
• Calibration parameter retention
• Small-scale non-volatile logging

Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'OT' matches the specific 8-lead package variant required for your design. Confirm RoHS compliance status directly from the manufacturer's datasheet before finalizing procurement specifications.

Selection Notes

Select this component when a 1 Kbit capacity is sufficient for application requirements. Ensure the system voltage remains within the 2.5 V to 5.5 V operating range. Verify that the host controller supports the standard SPI protocol and can manage the necessary chip select and hold signals for reliable communication.

Part Context

This part belongs to the 25LC010A family, which includes variants with different voltage ranges and packages. The 'LC' designation indicates a 2.5 V minimum operating voltage, distinguishing it from the 1.8 V capable 'AA' series. The 'T' suffix typically denotes tape and reel packaging availability.

Replacement Considerations

Cross-reference with other 25LC010A variants such as 25LC010AT-I/SN or 25LC010AT-I/MNY if package compatibility differs. Ensure any substitute maintains the same 2.5 V to 5.5 V voltage range and industrial temperature rating.
