24LC128-I/SNG

Memory IC Overview

The Microchip Technology 24LC128-I/SNG is a 128 Kbit (16K x 8) serial Electrically Erasable Programmable Read-Only Memory (EEPROM). It utilizes a two-wire I2C interface with a maximum clock frequency of 400 kHz. The device operates within a supply voltage range of 2.5 V to 5.5 V and features an access time of 900 ns. Packaged in an 8-pin SOIC (Narrow) format, it supports surface mount installation. The component is rated for industrial operating temperatures from -40°C to +85°C and offers a data retention period of 200 years.

Memory IC Procurement Notes

Verify the specific suffix 'I/SNG' against the official Microchip datasheet to confirm package dimensions and lead finish. Note that this part number may carry an NRND status; consult current manufacturer documentation for active production availability and lifecycle recommendations before finalizing procurement plans.

Memory IC Selection Notes

Select this component when a 128 Kbit capacity is required with I2C connectivity. Ensure the design accommodates the 2.5 V to 5.5 V supply range and the 8-SOIC footprint. Verify compatibility with the target system's I2C bus speed limits and temperature requirements.

Memory IC Part Context

This EEPROM belongs to the 24LC128 family, which shares functional specifications across various package options such as SOIC, TSSOP, and PDIP. The 'I' designation indicates industrial temperature rating, while 'SNG' specifies the narrow SOIC package variant. It is functionally compatible with other 24LC128 derivatives differing only in physical packaging.

Memory IC Replacement Considerations

Direct substitutes include 24LC128-I/SN and 24LC128T-I/SN. Verify pinout and electrical parameters match exactly. Cross-reference with 24AA128 or 24FC128 series if voltage or speed requirements differ.
