24LC04BHT-I/MNY

Memory IC Overview

The Microchip Technology 24LC04BHT-I/MNY is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire serial interface compatible with I2C protocols. It operates within a voltage range of 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device includes hardware write-protect functionality for the upper half of the memory array (addresses 100h-1FFh). It utilizes low-power CMOS technology, offering a maximum active read current of 1 mA and standby current of 5 µA at extended temperatures. The component is housed in an 8-lead TDFN package and is rated for industrial operating temperatures from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write-protect capability for the upper half of the memory array via the WP pin
• Low-power CMOS construction with minimal active and standby current consumption
• Integrated Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination

Memory IC Applications

• Data logging in industrial monitoring systems
• Configuration storage for embedded controllers
• Parameter retention in battery-backed circuits

Memory IC Procurement Notes

Verify that the ordering suffix 'MNY' corresponds specifically to the 8-lead TDFN package type as documented in the manufacturer's datasheet. Confirm the temperature grade 'I' matches the required industrial range of -40°C to +85°C for your specific application environment. Ensure compatibility with the 2.5V minimum supply voltage requirement before integration into the power design.

Memory IC Selection Notes

Select this component when a compact surface-mount solution is required for non-volatile data storage in space-constrained designs. The 24LC04BHT variant is suitable for applications needing half-array write protection without external logic. Consider the TDFN package dimensions against available PCB real estate and verify that the system power supply remains above 2.5V to ensure reliable operation across the full temperature range.

Memory IC Part Context

This part belongs to the 24XX04H family of 4-Kbit serial EEPROMs manufactured by Microchip Technology. The family shares common architectural features including page write capabilities and I2C compatibility but differs in supply voltage ranges and specific package options. The 24LC04BH series is distinct from the 24AA04H and 24FC04H variants primarily due to its higher minimum operating voltage specification.

Memory IC Replacement Considerations

Direct replacements include other packages within the same 24LC04BH family such as 24LC04BT-I/MS or 24LC04BHT-I/SN, provided the physical footprint and pinout are compatible.
