24LC04B-I/MC

Memory IC Overview

The Microchip Technology 24LC04B-I/MC is a 4-Kbit (512 x 8) serial EEPROM featuring an I²C interface. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes an 8-lead DFN package and functions across an industrial temperature range of -40°C to +85°C. Key electrical parameters include a maximum access time of 900 ns, active read current of 1 mA, and standby current of 5 µA at extended temperatures.

Memory IC Feature Summary

• Supports bidirectional two-wire serial communication compatible with standard I²C protocols
• Includes hardware write protection via the WP pin to inhibit memory writes when tied high
• Features Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control devices operating in noisy environments
• Consumer electronics utilizing low-power memory solutions

Memory IC Procurement Notes

Verify the specific suffix 'I/MC' corresponds to the Industrial temperature grade (-40°C to +85°C) and the 8-lead DFN package configuration. Confirm that the 2.5V minimum supply voltage requirement aligns with the target system's power rails, as this variant does not support operation below 2.5V unlike other members of the 24XX04 family.

Memory IC Selection Notes

Select this component when a 4-Kbit capacity is required with strict adherence to the 2.5V to 5.5V operating voltage window. The Industrial temperature rating makes it suitable for general-purpose applications where extreme cold or heat resistance is not mandated. Ensure the design accommodates the 400 kHz maximum clock speed and utilizes appropriate pull-up resistors for the SDA and SCL lines.

Memory IC Part Context

This part belongs to the 24LC04B series, which is distinguished from the 24AA04 by its higher minimum operating voltage of 2.5V. While sharing the same 4-Kbit architecture and I²C interface, the 24LC04B is optimized for standard 3.3V and 5V logic systems. The 'MC' designation specifically identifies the 8-lead Dual Flat No-Lead (DFN) surface-mount package type.

Memory IC Replacement Considerations

The 24LC04BT-I/MS serves as a direct functional substitute offering identical electrical specifications but housed in an 8-lead MSOP package instead of the DFN format.
