24LC08B-I/SN

Memory IC Overview

The Microchip Technology 24LC08B-I/SN 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 2-Wire Serial Interface compatible with I²C protocols. The device features a maximum access time of 900 ns, a standby current of up to 5 µA at extended temperatures, and a write cycle time of 5 ms maximum. It is housed in an 8-lead SOIC package and rated for industrial operating temperatures between -40°C and +85°C.

Memory IC Feature Summary

• Supports bidirectional two-wire serial data transmission protocol compatible with I²C standards.
• Includes hardware write protection controlled by the WP pin to inhibit write operations when tied high.
• Features Schmitt trigger inputs and filter circuits on SDA and SCL pins to suppress noise spikes.
• Provides output slope control designed to eliminate ground bounce during signal transitions.

Memory IC Applications

• Non-volatile data storage for system configuration parameters.
• Calibration value retention in industrial instrumentation.
• Device identification and tracking information logging.
• Parameter storage in consumer electronics requiring low power consumption.

Memory IC Procurement Notes

Verify the specific suffix 'I' confirms the industrial temperature range (-40°C to +85°C) and 'SN' denotes the 8-lead SOIC package. Confirm that the 2.5V minimum operating voltage requirement aligns with the target system's power supply rails, as this variant does not support operation below 2.5V unlike other members of the 24XX08 family.

Memory IC Selection Notes

Select this component when a standard 8-Kbit EEPROM capacity is required with I²C interface compatibility. Ensure the application environment stays within the specified industrial temperature limits. Consider the 16-byte page write buffer capability if sequential data writing is frequent. Verify that the host controller can generate the necessary Start and Stop conditions for proper bus communication.

Memory IC Part Context

This part belongs to the 24XX08 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA08 and 24FC08 but differs in voltage specifications and clock speed capabilities. The 24LC08B specifically targets applications requiring operation down to 2.5V, distinguishing it from lower-voltage or higher-speed variants within the same memory density class.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC08BT-I/SN and 24LC08BH-I/ST. Verify package compatibility and voltage ranges before substitution.
