24LC01B/P

Memory IC Overview

The Microchip Technology 24LC01B/P is a 1 Kbit (128 x 8) Electrically Erasable PROM (EEPROM) housed in an 8-Lead PDIP package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and features a 2-Wire I2C compatible serial interface with a maximum clock frequency of 400 kHz. The device supports page write operations with an 8-byte buffer and includes hardware write protection via the WP pin. It offers data retention exceeding 200 years and endurance of over one million erase/write cycles.

Memory IC Feature Summary

• Supports bidirectional 2-wire serial communication using I2C protocol
• Includes hardware write-protect capability for memory security
• Features Schmitt trigger inputs and output slope control for noise suppression
• Provides self-timed erase and write cycles with automatic termination

Memory IC Applications

• Non-volatile data storage in industrial control systems
• Configuration parameter retention in embedded devices
• Calibration data storage for sensor modules
• Device identification and serial number recording

Memory IC Procurement Notes

Verify that the ordering suffix 'P' corresponds specifically to the 8-Lead Plastic Dual In-Line (PDIP) package type as documented in the datasheet. Confirm the voltage range requirement matches the 2.5V to 5.5V specification for the 24LC01B series, distinct from lower voltage variants like the 24AA01. Ensure compatibility with the intended operating temperature range for industrial applications.

Memory IC Selection Notes

Select this component when through-hole mounting is required for the 1 Kbit EEPROM capacity. The 24LC01B variant is specified for operation starting at 2.5 V, which differs from the 1.7 V minimum of the 24AA01. Consider the 8-byte page write buffer for efficient data writing. Verify that the system bus speed does not exceed the 400 kHz limit under the applicable supply voltage conditions.

Memory IC Part Context

This part belongs to the 24XX01 family of 1 Kbit Serial EEPROMs manufactured by Microchip Technology. The family includes the 24AA01 and 24FC01, which share similar interfaces but differ in voltage ranges and clock speeds. The 24LC01B is optimized for standard 5 V and 3.3 V logic levels within the industrial temperature grade.

Memory IC Replacement Considerations

Direct functional substitutes within the same package include other 24LC01B variants such as 24LC01BT-I/SN or 24LC01BH-E/SN, though these may differ in package type (SOIC/MSOP) or temperature grade. Cross-family replacements like the 24AA01 require verification of the minimum supply voltage compatibility.
