24LC00/WF

Memory IC Overview

The Microchip Technology 24LC00/WF is a 128-bit (16 x 8) serial EEPROM utilizing an I2C-compatible 2-wire interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies of 100 kHz and 400 kHz. The device features Schmitt trigger inputs for noise suppression, output slope control to eliminate ground bounce, and ESD protection exceeding 4000V. Designed for low-power applications, it draws typical active current of 500 µA and standby current of 100 nA. Data retention exceeds 200 years with over 1 million erase/write cycles.

• Schmitt trigger inputs and output slope control designed to suppress noise spikes and eliminate ground bounce
• High reliability specifications including over 1 million erase/write cycles and data retention exceeding 200 years

Memory IC Applications

• Storage of calibration values in electronic systems
• Recording ID numbers for device identification
• Logging manufacturing information during production
• General non-volatile data storage requiring small memory capacity

Memory IC Procurement Notes

Verify the specific package suffix 'WF' against official Microchip documentation to confirm the wafer form factor, as standard retail packages include PDIP, SOIC, TSSOP, DFN, and SOT-23. Ensure the industrial temperature range (-40°C to +85°C) meets system requirements. Confirm RoHS compliance status for the specific lot. Cross-reference the datasheet DS20001178J for accurate electrical characteristics and pin configurations before integration.

Memory IC Selection Notes

Select this component when a small, non-volatile memory footprint is required for storing static configuration data or identifiers. The 24LC00 is suitable for systems where power consumption must be minimized during idle states. Choose this part over the 24AA00 if the minimum operating voltage requirement is 2.5V rather than 1.8V. Consider the available package options, such as wafer form, based on assembly constraints and board space limitations.

Memory IC Part Context

The 24LC00 belongs to the 24XX00 family of serial EEPROMs manufactured by Microchip Technology. This family includes variants like the 24AA00 and 24C00, which share similar interfaces but differ in voltage ranges and temperature ratings. The 24LC00 specifically targets industrial applications with a 2.5V to 5.5V operating range. It serves as a compact solution for applications needing reliable, low-power data storage without complex interface protocols.
