24LC01B-I/P

Memory IC Overview

The Microchip Technology 24LC01B-I/P is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) housed in an 8-lead Plastic Dual In-Line (PDIP) package. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via a 2-wire I2C compatible serial interface. The device features Schmitt trigger inputs for noise suppression, hardware write protection, and output slope control. It is rated for industrial temperature operation between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional data transmission using a standard 2-wire I2C compatible serial bus protocol.
• Includes an 8-byte page write buffer to allow efficient sequential data storage operations.
• Provides hardware-based write protection through the WP pin to prevent unintended memory modifications.

Memory IC Applications

• Non-volatile data storage for system configuration parameters
• Calibration value retention in embedded systems
• Device identification and serial number logging

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'P' indicates the 8-lead PDIP package. Confirm the specific datasheet revision matches your design requirements. Ensure power supply voltages remain within the specified 2.5V to 5.5V operational limits during procurement validation.

Memory IC Selection Notes

Select this component when a robust through-hole mounting solution is required for low-density non-volatile memory applications. The 24LC01B-I/P is suitable for designs operating at standard I2C speeds up to 400 kHz with a 2.5V minimum supply voltage. Consider alternative packages like SOIC or TSSOP if surface mount technology is preferred for the assembly process.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes variants such as the 24AA01 and 24FC01, which differ primarily in their minimum operating voltage and maximum clock frequency specifications while sharing similar functional architectures and interface protocols.

Memory IC Replacement Considerations

Direct replacements include other 24LC01B variants with different packages, such as 24LC01B-I/SN (SOIC) or 24LC01B-I/ST (TSSOP). Cross-family substitutes like the 24AA01 offer lower voltage operation but may require level shifting if the system voltage drops below 2.5V.
