24LC01BHT-I/OT

Memory IC Overview

The Microchip Technology 24LC01BHT-I/OT is a 1 Kbit (128 x 8) Electrically Erasable PROM featuring a 2-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device utilizes Low-Power CMOS technology, offering a maximum read current of 1 mA and standby current of 1 μA. It supports page writes of up to 8 bytes and includes hardware write-protect functionality for half the array. The component is housed in a 5-lead SOT-23 package and is rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Hardware Write-Protect: Enables protection of the upper half of the memory array via the WP pin.
• Low-Power Operation: Designed for low active and standby currents suitable for battery-powered applications.
• I2C Compatibility: Supports standard and fast mode communication protocols with Schmitt trigger inputs.
• High Reliability: Offers extensive endurance cycles and long-term data retention capabilities.

Memory IC Applications

• Embedded systems requiring non-volatile configuration storage

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required temperature grade and package type. Confirm RoHS compliance status and lead-free availability through official manufacturer documentation before finalizing procurement orders.

Memory IC Selection Notes

Select this component when a compact 5-lead surface mount package is required alongside I2C connectivity. Ensure the system voltage remains within the specified 2.5V to 5.5V range to maintain proper operation and timing specifications.

Memory IC Part Context

This part belongs to the 24LC01BH family of 1 Kbit serial EEPROMs. It shares core electrical characteristics with other variants in the series but differs in physical packaging and specific temperature ratings defined by its suffix codes.

Memory IC Replacement Considerations

Direct substitutes include other 24LC01BH variants such as 24LC01BHT-I/SN or 24LC01BHT-I/LT, provided the package footprint and voltage requirements align with the design constraints.

Memory IC FAQ

How does the hardware write-protect feature function?

Connecting the WP pin to VCC inhibits write operations to the upper half of the memory array (addresses 40h-7Fh), while connecting it to VSS enables full read/write access.

What is the maximum page write size?

The device supports page write operations of up to 8 bytes, allowing multiple data words to be transferred before initiating an internal write cycle.
