24LC04BH-I/P

Memory IC Overview

The Microchip Technology 24LC04BH-I/P is a 4-Kbit (512 x 8) Electrically Erasable PROM (EEPROM) featuring a two-wire serial interface compatible with I2C. 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 (addresses 100h-1FFh). It utilizes an 8-Lead Plastic Dual In-Line (PDIP) package and is rated for industrial temperature operation from -40°C to +85°C.

Memory IC Feature Summary

• Hardware write protection capability for the upper half of the memory array via the WP pin
• Low-power CMOS technology with standby current as low as 5 µA at extended temperatures
• Schmitt trigger inputs and output slope control for noise suppression and ground bounce elimination
• Self-timed erase/write cycles with automatic termination

Memory IC Applications

• Embedded systems requiring non-volatile data storage
• Industrial control applications operating in harsh environments
• Consumer electronics utilizing I2C communication protocols
• Device calibration parameter storage

Memory IC Procurement Notes

Verify that the specific ordering suffix matches the required package type, temperature grade, and voltage specifications. Confirm compliance with RoHS directives and automotive qualification standards if applicable to the target application environment. Ensure the selected variant aligns with the system's power supply constraints and interface timing requirements.

Memory IC Selection Notes

Select this component when a 4-Kbit EEPROM with I2C compatibility is required. The 'I' suffix indicates industrial temperature range suitability. The 'P' suffix designates the PDIP package. Ensure the system voltage remains above 2.5V for proper operation. Consider the page write buffer size and write cycle time when designing software drivers for optimal bus throughput.

Memory IC Part Context

This part belongs to the 24XX04H series, which also includes the 24AA04H and 24FC04H variants. These devices share similar architectural features but differ in minimum operating voltage and maximum clock frequency capabilities. The 24LC04BH specifically targets applications requiring a 2.5V minimum supply voltage.

Memory IC Replacement Considerations

Direct substitutes include other 24LC04BH variants with different packages such as SOIC or MSOP. Cross-referencing with the 24AA04H or 24FC04H requires verification of voltage and speed compatibility.
