24LC02B-I/S15K

Memory IC Overview

The Microchip Technology 24LC02B-I/S15K is a 2-Kbit (256 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire I2C compatible serial interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device supports an 8-byte page write buffer and includes hardware write protection via the WP pin. It is housed in a 5-lead SC-70 package, rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional data transfer using a standard two-wire serial bus protocol.
• Includes Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination.
• Features self-timed erase/write cycles with automatic internal timing control.

Memory IC Applications

• Data storage in low-power embedded systems
• Configuration memory for microcontrollers
• Parameter storage in consumer electronics

Memory IC Procurement Notes

Verify that the ordering suffix 'S15K' corresponds to the specific reel or tape-and-reel packaging configuration provided by the manufacturer. Confirm the component meets RoHS compliance standards and matches the specified industrial temperature range requirements for your application environment.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for small-scale non-volatile data retention. Ensure the system design accommodates the 2.5V minimum operating voltage and utilizes appropriate pull-up resistors for the I2C bus lines to maintain signal integrity at the specified clock speeds.

Memory IC Part Context

This part belongs to the 24XX02 family of serial EEPROMs, which also includes the 24AA02 and 24FC02 variants. While sharing similar architectural features, the 24LC02B series is specifically optimized for operation starting at 2.5V, distinguishing it from lower-voltage counterparts within the same product line.

Memory IC Replacement Considerations

Direct replacements include other 24LC02B variants with different packages such as SOIC or PDIP, or alternative manufacturers offering functionally equivalent 2Kb I2C EEPROMs. Verify pin compatibility and voltage specifications before substitution.

Memory IC FAQ

How does the hardware write-protect feature function?

Connecting the WP pin to VCC inhibits all write operations, protecting the entire memory array. Connecting it to VSS enables normal read and write access.

What is the purpose of the page write buffer?

The 8-byte page write buffer allows multiple bytes to be transmitted and stored internally before being written to the memory array upon receipt of a Stop condition, improving bus efficiency.
