24LC01BH-I/SN

Memory IC Overview

The Microchip Technology 24LC01BH-I/SN is a 1 Kbit Electrically Erasable PROM organized as one block of 128 x 8-bit memory. It features a 2-wire serial interface compatible with I²C™, supporting maximum clock frequencies of 100 kHz and 400 kHz. The device operates on a single supply voltage ranging from 2.5V to 5.5V. It includes hardware write-protect functionality for half the array (addresses 40h-7Fh) via the WP pin. The component utilizes low-power CMOS technology, ensuring standby current remains at or below 1 μA.

Memory IC Feature Summary

• Hardware write-protect capability allows selective protection of the upper half of the memory array.
• Schmitt trigger inputs provide noise suppression for reliable data transmission.
• Output slope control minimizes ground bounce during switching operations.
• Supports acknowledge polling to maximize bus throughput during internal write cycles.

Memory IC Applications

• Industrial embedded systems requiring non-volatile data storage
• Low-power consumer electronics utilizing I²C communication
• Automotive applications operating within specified temperature ranges

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type and temperature grade. Confirm that the device variant aligns with the necessary voltage range, as this model requires a minimum of 2.5V. Ensure compatibility with existing I²C bus protocols and check for any specific manufacturing change notices relevant to the production batch.

Memory IC Selection Notes

Select this component when a 1 Kbit EEPROM with I²C interface is required for industrial environments. It is suitable for designs needing hardware write protection for specific memory sections. Consider the SOIC-8 surface mount package for PCB layout constraints. Verify that the system power supply meets the minimum 2.5V requirement for proper operation.

Memory IC Part Context

This part belongs to the 24AA01H/24LC01BH family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The 'I' designation indicates an industrial temperature range rating. The 'SN' suffix specifies the 8-lead Small Outline Integrated Circuit (SOIC) package with a standard 3.90 mm width. This series provides a cost-effective solution for small data storage needs in microcontroller-based systems.

Memory IC Replacement Considerations

The 24LC01BHT-I/SN serves as a verified tape-and-reel replacement for the 24LC01BH-I/SN, offering identical electrical characteristics and functionality while differing only in packaging format.
