24VL024H/P

Memory IC Overview

The Microchip Technology 24VL024H/P is a 2 Kbit (256 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 1.5 V to 3.6 V and supports I2C compatible 2-wire serial interfaces with maximum clock frequencies of 100 kHz or 400 kHz. The device features a page write buffer for up to 16 bytes, hardware write protection for the upper half of the array, and low-power CMOS technology ensuring standby currents as low as 1 μA.

Memory IC Feature Summary

• Hardware write protection capability that locks the upper half of the memory array when the WP pin is tied high
• Low-power CMOS design enabling operation down to 1.5V with minimal active and standby current consumption
• I2C compatible 2-wire serial interface supporting bus speeds up to 400 kHz with Schmitt trigger inputs for noise suppression

Memory IC Applications

• Battery-powered sensor nodes requiring extended data retention and low power consumption
• Industrial controllers needing hardware-level protection against accidental data overwrites
• Embedded systems utilizing cascaded I2C buses for expanded contiguous memory addressing

Memory IC Procurement Notes

Verify the specific package suffix matches the required form factor, as the 'P' designation indicates an 8-pin PDIP package. Confirm RoHS compliance status through official documentation prior to integration. Ensure the operating voltage range aligns with the system's 1.5V to 3.6V supply constraints. Validate temperature ratings for the intended industrial environment.

Memory IC Selection Notes

Select this component when a non-volatile storage solution is needed that supports voltages below 2.5V, which standard EEPROMs may not accommodate. The integrated hardware write-protect feature distinguishes it from software-only protected alternatives. Consider the PDIP package availability if through-hole mounting is mandatory for the target PCB design.

Memory IC Part Context

This part belongs to the 24VL024 family of serial EEPROMs designed for ultra-low voltage applications. Unlike the 24LC series which typically requires higher minimum voltages, the VL variant specifically targets 1.5V operation. The '/P' suffix explicitly defines the physical packaging as an 8-pin plastic dual in-line package suitable for breadboard or through-hole prototyping.

Memory IC Replacement Considerations

The 24LC024H serves as a functional substitute but requires a minimum supply voltage of 1.7V, whereas the 24VL024H supports 1.5V. Verify that the application voltage remains above 1.7V if substituting. Both devices share identical pinouts and I2C protocols.
