24LC01BH-E/P

Memory IC Overview

The Microchip Technology 24LC01BH-E/P 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™ protocols, supporting maximum clock frequencies up to 400 kHz. The device operates on a single supply voltage ranging from 2.5 V to 5.5 V and utilizes low-power CMOS technology. It is housed in an 8-lead PDIP package and supports industrial temperature ranges.

Memory IC Feature Summary

• Hardware write-protect capability for half-array protection
• Schmitt trigger inputs for noise suppression
• Output slope control to eliminate ground bounce
• High endurance exceeding one million erase/write cycles

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial applications operating within extended temperature ranges
• Automotive electronic modules
• Low-voltage portable devices

Memory IC Procurement Notes

Verify the specific suffix 'E' indicates automotive grade qualification (-40°C to +125°C) versus standard industrial grade. Confirm the '/P' designation corresponds to the 8-lead PDIP through-hole package. Ensure compatibility with system voltage requirements, as this variant requires a minimum of 2.5 V compared to lower-voltage alternatives.

Memory IC Selection Notes

Select this component when automotive-grade temperature stability is required alongside standard I²C communication. The 8-lead PDIP package facilitates prototyping and through-hole assembly. Consider page write capabilities for efficient data handling. Verify that the 2.5 V minimum supply voltage aligns with the target system's power rails.

Memory IC Part Context

This part belongs to the 24AA01H/24LC01BH family of 1 Kbit serial EEPROMs. The 'L' in the model name denotes operation down to 2.5 V, distinguishing it from the 'A' series which supports lower voltages. The 'BH' suffix typically indicates specific packaging or feature sets within the broader 24LC01B product line.

Memory IC FAQ

What is the function of the WP pin?

The Write-Protect (WP) pin allows hardware protection of the upper half of the memory array (addresses 40h-7Fh) when tied to VCC.

How does the device handle bus collisions?

The device uses Acknowledge polling; it does not generate ACK signals during internal write cycles, allowing the master to detect readiness.
