24LC08B-I/ST

Memory IC Overview

The Microchip Technology 24LC08B-I/ST is an 8-Kbit Electrically Erasable PROM (EEPROM) organized as four blocks of 256 x 8-bit memory. It operates with a single supply voltage ranging from 2.5V to 5.5V and supports a maximum clock frequency of 400 kHz via a two-wire serial interface compatible with I²C protocols. The device features Schmitt trigger inputs for noise suppression, hardware write protection, and output slope control to eliminate ground bounce. It provides over one million erase/write cycles and data retention exceeding 200 years.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication with I²C compatibility
• Includes hardware write-protect capability controlled by the WP pin
• Features Schmitt trigger inputs and filter circuits for noise suppression
• Provides self-timed erase/write cycles with automatic page buffer management

Memory IC Applications

• Non-volatile data storage in industrial control systems
• Configuration parameter storage in consumer electronics
• Device identification and calibration data logging
• Embedded system settings retention in automotive applications

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature range (-40°C to +85°C) and 'ST' indicates the 8-Lead SOIC package. Confirm the specific revision level matches your design requirements. Ensure the supply voltage meets the minimum 2.5V threshold required for this variant. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Memory IC Selection Notes

Select this component when a low-pin-count non-volatile memory solution is required for I²C bus integration. The 8Kb capacity suits applications needing moderate data retention without complex addressing schemes. Consider the 400 kHz speed limit for high-frequency bus environments. Evaluate the 8-SOIC footprint against available PCB real estate constraints.

Memory IC Part Context

This part belongs to the 24XX08 family, which includes variants like the 24AA08 and 24FC08. While sharing similar architecture, the 24LC08B is distinguished by its 2.5V minimum operating voltage compared to the 1.7V support in other family members. It utilizes standard I²C addressing protocols common across Microchip's serial EEPROM portfolio.

Memory IC Replacement Considerations

Direct substitutes include the 24LC08BT-I/ST for tape-and-reel packaging or the 24LC08B-I/SN for alternative SOIC dimensions. Cross-family replacements like the 24AA08 require verification of the lower voltage operation compatibility.
