24LC02B-I/P

Memory IC Overview

The Microchip Technology 24LC02B-I/P is a 2-Kbit (256 x 8) serial EEPROM housed in an 8-pin PDIP package. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports I2C compatible two-wire serial interfaces with clock frequencies up to 400 kHz at VCC ≥ 2.5V. The device features a maximum access time of 900 ns, a page write buffer for 8 bytes, and a self-timed write cycle of 5 ms maximum. It is rated for industrial temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial interface compatible with the I2C protocol
• Includes hardware write-protect capability via the WP pin
• Features Schmitt trigger inputs and output slope control for noise suppression

Memory IC Applications

• Data storage in low-power embedded systems
• Configuration parameter retention in industrial controllers
• Device identification and calibration data 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 revision level matches the design requirements, as datasheet revisions may update electrical characteristics or packaging details. Ensure compatibility with the host system's I2C bus voltage levels.

Memory IC Selection Notes

Select this component when a non-volatile memory solution requires a through-hole mounting option for prototyping or high-reliability applications. The 24LC02B variant specifically requires a minimum supply voltage of 2.5V, distinguishing it from lower-voltage counterparts like the 24AA02. Consider the 8-byte page write buffer efficiency for sequential data operations versus byte-write overhead.

Memory IC Part Context

This part belongs to the 24XX02 family of Electrically Erasable PROMs, which includes the 24AA02, 24LC02B, and 24FC02 devices. While sharing the same 2-Kbit capacity and core architecture, the 24LC02B is optimized for standard voltage operation starting at 2.5V, whereas other family members support lower voltages or higher clock speeds.

Memory IC Replacement Considerations

The 24LC02B/SN serves as a surface-mount equivalent within the same functional family. For lower voltage applications requiring 1.7V operation, the 24AA02 series is a functional alternative. Verify package type and temperature grade when substituting.
