24LC044-E/ST

Memory IC Overview

The Microchip Technology 24LC044-E/ST is a 4-Kbit (512 x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It operates on a single supply voltage ranging from 2.5 V to 5.5 V and supports I²C bus interfaces with clock frequencies up to 400 kHz. The device features an access time of 900 ns and is housed in an 8-pin TSSOP package. Designed for industrial temperature ranges, it ensures data retention for over 200 years.

Memory IC Feature Summary

• Supports high-speed I²C communication protocols at standard and fast modes
• Provides non-volatile storage with extended data retention capabilities
• Operates reliably across wide industrial temperature conditions

Memory IC Applications

• Industrial control systems requiring persistent parameter storage
• Consumer electronics needing configuration data retention
• Embedded devices utilizing low-power serial memory solutions

Memory IC Procurement Notes

Verify the specific suffix 'E' confirms the extended industrial temperature range and 'ST' denotes the TSSOP-8 package. Confirm RoHS compliance status through official datasheets or manufacturer declarations before integration into regulated assemblies. Ensure voltage levels match system requirements strictly within the 2.5V to 5.5V operational window.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is required with I²C interface compatibility. It is suitable for designs needing robust data retention and operation within industrial thermal limits. Compare against the 24LC044-I variant if commercial temperature grades suffice, or consider alternative packages if footprint constraints differ from TSSOP-8 dimensions.

Memory IC Part Context

This part belongs to the Microchip 24LC0xx series of serial EEPROMs, which are widely used for small-scale data storage in embedded applications. The series offers various capacities and interface options, with the 24LC044 specifically providing 512 bytes of organized memory accessible via two-wire serial communication lines.

Memory IC Replacement Considerations

Direct substitutes include other 4-Kbit I²C EEPROMs from Microchip such as the 24LC044-I/ST for commercial grade or 24AA044 variants. Cross-brand replacements require verification of pinout compatibility and voltage level alignment.
