24LC08B/P

Memory IC Overview

The Microchip Technology 24LC08B/P is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It features a two-wire serial interface compatible with the I2C protocol. The device operates on a single supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz. It includes hardware write protection, Schmitt trigger inputs for noise suppression, and output slope control. The Industrial temperature grade version functions within a range of -40°C to +85°C.

Memory IC Feature Summary

• Supports bidirectional data transmission via a standard two-wire serial bus interface.
• Includes hardware write-protect capability to inhibit write operations when the WP pin is tied high.
• Features Schmitt trigger inputs and filter circuits to suppress noise spikes on the SCL and SDA lines.

Memory IC Applications

• Non-volatile data storage in industrial control systems
• Configuration parameter retention in embedded devices
• Device identification and calibration data logging

Memory IC Procurement Notes

Verify that the ordering suffix 'P' corresponds specifically to the 8-Lead PDIP package type. Confirm the temperature grade matches the required operational environment, as the 'I' suffix denotes Industrial range (-40°C to +85°C). Ensure the design accommodates the 2.5V minimum operating voltage specific to the 24LC08B series rather than lower voltage variants.

Memory IC Selection Notes

Select this component when a robust through-hole solution is required for I2C-based memory applications. The 24LC08B/P offers higher voltage tolerance compared to 1.7V variants, making it suitable for 5V logic systems. Consider the page write buffer size and write cycle time if high-frequency data logging is necessary. Verify that the physical footprint of the 8-Lead PDIP package fits the target PCB layout constraints.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. It shares architectural similarities with the 24AA08 and 24FC08 but differs in operating voltage and clock speed specifications. The 24LC08B is optimized for standard 2.5V to 5.5V operation, distinguishing it from low-voltage counterparts.

Memory IC Replacement Considerations

Direct replacements include other 24LC08B variants with different packages such as SOIC or TSSOP, provided the pinout remains compatible. Cross-referencing with 24AA08 requires verification of the minimum supply voltage compatibility.
