24VL024/P

Memory IC Overview

The Microchip Technology 24VL024/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 hardware write protection for the entire array, low-power CMOS technology with standby current up to 1 μA, and data retention exceeding 200 years. It is housed in an 8-pin PDIP package.

Memory IC Feature Summary

• Hardware write protection for the entire memory array via dedicated pin
• Low-power operation with active current up to 400 μA and standby current up to 1 μA
• Supports cascading up to eight devices on the same bus using configurable chip select inputs
• Schmitt trigger inputs provide noise suppression and improved spike filtering

Memory IC Applications

• Data logging applications requiring non-volatile storage
• Configuration storage in battery-powered embedded systems
• Parameter storage in industrial control equipment
• Smart metering and utility monitoring devices

Memory IC Procurement Notes

Verify that the specific part number corresponds to the 8-pin PDIP package variant. Confirm the operating temperature range requirements align with the specified -20°C to +85°C limits. Ensure the design accommodates the hardware write protection functionality unique to this model compared to similar variants without the WP pin.

Memory IC Selection Notes

Select this component when full-array hardware write protection is required alongside low-voltage operation down to 1.5 V. It is suitable for designs needing I²C compatibility with standard noise immunity features. Consider the PDIP package constraints if surface-mount space is limited. Verify that the 256-byte organization fits the application's data storage needs.

Memory IC Part Context

This component belongs to the 24VL024/24VL025 family of 2 Kbit serial EEPROMs manufactured by Microchip Technology. The 'P' suffix specifically denotes the 8-pin plastic dual in-line package (PDIP). It shares core electrical characteristics with other packages in the series but differs in physical form factor and pin configuration availability.

Memory IC Replacement Considerations

Direct replacements include other 24VL024 variants such as 24VL024/SN, 24VL024/TSSOP, or 24VL024/MSOP, provided the PCB layout accommodates the respective package type. Cross-referencing with 24LC024 models requires verification of voltage range differences.
