Microchip 24LC01BH-E/MS: A Comprehensive Datasheet Overview

The Microchip 24LC01BH-E/MS is a 1 Kbit Serial Electrically Erasable PROM (EEPROM) memory chip, designed for low-power, high-performance applications requiring reliable non-volatile data storage. This device is organized as a single block of 128 x 8 (1K) and communicates via the ubiquitous I2C (Inter-Integrated Circuit) serial interface, making it an ideal solution for space-constrained designs across consumer, industrial, and automotive electronics.

A key feature of this EEPROM is its wide voltage operation range from 1.7V to 5.5V. This flexibility allows it to be seamlessly integrated into systems powered by various sources, from a single-cell lithium battery to a standard 5V rail. Coupled with its low power consumption, characterized by a standby current of just 1 µA (max.) and an active read current of 1 mA (max.), the device is exceptionally well-suited for battery-powered and portable applications.

The 24LC01BH-E/MS supports the full I2C protocol, operating in both Standard (100 kHz) and Fast (400 kHz) modes. It includes vital hardware data protection through the WP (Write Protect) pin, which when tied high, prevents any write operations to the entire memory array, safeguarding critical data from accidental corruption. The chip also features page write capability for up to 8 bytes of data, allowing for more efficient programming and faster system throughput.

Housed in a compact 8-pin MSOP package, the device offers a minimal footprint on printed circuit boards. Its robust design ensures high endurance, supporting 1 million erase/write cycles per byte and data retention of over 200 years, guaranteeing long-term reliability. The extended industrial temperature range (-40°C to +85°C) further ensures stable operation in harsh environments.

ICGOODFIND: The Microchip 24LC01BH-E/MS stands out as a highly reliable and versatile 1K serial EEPROM. Its combination of a wide voltage range, ultra-low power consumption, robust data protection, and a tiny form factor makes it an superior choice for designers seeking efficient non-volatile memory in modern electronic systems.
