24LC04BHT-I/MS

Memory IC Overview

The Microchip Technology 24LC04BHT-I/MS 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 protection for the upper half of the memory array, a 16-byte page write buffer, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead MSOP package and functions reliably across an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection enables selective inhibition of write operations for the upper half of the memory array via the WP pin.
• Integrated 16-byte page write buffer allows efficient data transfer by storing multiple bytes before initiating an internal write cycle.
• Schmitt trigger inputs on SDA and SCL lines provide noise suppression to ensure stable operation in electrically noisy environments.

Memory IC Applications

• Embedded systems requiring non-volatile storage for configuration parameters
• Industrial control devices needing reliable data retention under varying environmental conditions
• Consumer electronics utilizing low-power memory for small data sets

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP package type and Industrial temperature grade. Confirm RoHS compliance status as required by project specifications. Ensure compatibility with existing I2C bus pull-up resistor values for the target operating voltage. Check for any recent product change notices affecting packaging or electrical characteristics.

Memory IC Selection Notes

Select this component when a 4-Kbit EEPROM with I2C interface is required for industrial applications. The MSOP package is suitable for space-constrained surface-mount designs. Consider the 2.5V minimum supply voltage constraint compared to lower-voltage alternatives. Verify that the hardware write protection feature meets the system's security requirements for memory integrity.

Memory IC Part Context

This part belongs to the 24LC04BH series of 4-Kbit serial EEPROMs manufactured by Microchip Technology. The series shares common electrical characteristics and interface protocols but differs in package options and temperature grades. The 'I' designation indicates the Industrial temperature range, while 'MS' specifies the 8-lead Mini Small Outline Package.

Memory IC Replacement Considerations

Direct replacements include other 24LC04BH variants with different packages such as SOIC or TSSOP, provided the pinout remains compatible. Cross-reference with 24AA04H or 24FC04H only if voltage ranges and clock speeds align with system requirements. Verify that substitute parts maintain the same half-array write protection functionality.
