24VL024/MS

Memory IC Overview

The Microchip Technology 24VL024/MS is a 2 Kbit Serial Electrically Erasable PROM organized as a single block of 256 x 8-bit memory. It operates on a single supply ranging from 1.5V to 3.6V with a maximum clock frequency of 400 kHz, reducing to 100 kHz when VCC is below 1.8V. The device features low-power CMOS technology with a maximum active current of 400 μA and standby current of 1 μA. It supports I2C compatible 2-wire serial interface, hardware write protection for the entire array, and a page write buffer for up to 16 bytes.

Memory IC Feature Summary

• Hardware write protection for the entire array via dedicated WP pin
• I2C compatible 2-wire serial interface with Schmitt trigger inputs
• Low-power operation with minimal active and standby currents
• Page write buffer capability for efficient data storage

Memory IC Applications

• Battery-powered devices requiring low standby current
• Systems needing hardware-enforced data protection
• Embedded applications utilizing I2C bus communication
• Portable electronics operating at voltages down to 1.5V

Memory IC Procurement Notes

Verify that the specific ordering suffix corresponds to the MSOP package type, as the base part number covers multiple packages. Confirm RoHS compliance status if required by your manufacturing standards. Ensure the procurement channel provides genuine Microchip Technology products to guarantee reliability and access to official documentation. Check for any specific temperature grade requirements within the -20°C to +85°C range.

Memory IC Selection Notes

Select this component when hardware write protection is mandatory for the entire memory array, distinguishing it from the 24VL025 variant which lacks the WP pin. Choose the MSOP package for space-constrained designs requiring an 8-pin surface-mount solution. Consider the 1.5V minimum operating voltage for ultra-low power applications. Verify that the I2C bus speed requirements align with the 400 kHz maximum specification at appropriate supply voltages.

Memory IC Part Context

This component belongs to the 24VL02x family of 2 Kbit Serial EEPROMs from Microchip Technology. It shares core electrical characteristics and interface protocols with the 24VL025, differing primarily in the inclusion of a hardware write-protect pin. The family supports various package options including PDIP, SOIC, TSSOP, TDFN, and MSOP, catering to diverse PCB layout needs.

Memory IC Replacement Considerations

The 24VL025 serves as a functional substitute if hardware write protection is not required, though the WP pin must be handled appropriately. Other 2 Kbit I2C EEPROMs may replace it only if voltage ranges, interface timing, and package dimensions are verified compatible. Direct pin-for-pin replacement requires confirming the absence of the WP pin functionality or tying it to a valid logic level.
