24VL024HT/SN

Memory IC Overview

The Microchip Technology 24VL024HT/SN is a 2 Kbit (256 x 8) serial EEPROM utilizing an I²C-compatible 2-wire interface. It operates on a single supply voltage ranging from 1.5 V to 3.6 V and supports clock frequencies up to 400 kHz, with 100 kHz compatibility at voltages below 1.8 V. The device features Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce. It includes hardware write protection for the upper half of the array (addresses 80h-FFh) via the WP pin. The component is housed in an 8-pin SOIC package and functions within an ambient temperature range of -20°C to +85°C.

Memory IC Feature Summary

• Hardware write protection enables selective locking of the upper memory half via the WP pin
• Integrated Schmitt triggers and spike suppression filters ensure reliable data transmission on noisy buses
• Page write buffer allows storage of up to 16 bytes before initiating an internal self-timed write cycle
• Supports cascading up to eight devices on a single bus using configurable chip select address lines

Memory IC Applications

• Low-power embedded systems requiring non-volatile data retention
• Industrial controllers operating under noisy electrical conditions
• Battery-powered devices utilizing low-voltage power supplies
• Systems requiring hardware-enforced protection for critical configuration data

Memory IC Procurement Notes

Verify that the ordering suffix 'SN' corresponds specifically to the 8-pin SOIC package variant. Confirm the presence of the 'T' designation indicates tape-and-reel packaging if reel supply is required. Ensure the selected part number matches the specific temperature grade and voltage requirements of the target application circuit design.

Memory IC Selection Notes

Select this component when operation down to 1.5 V is necessary, as standard variants may require higher voltages. Choose the SOIC package for surface-mount assembly constraints. Consider the half-array write protection feature if specific memory regions require permanent safeguarding against accidental overwrites during normal operation.

Memory IC Part Context

This device belongs to the 24VL024H family of 2-Kbit serial EEPROMs manufactured by Microchip Technology. The family utilizes low-power CMOS technology designed for high endurance and long-term data retention. Variants within the series differ primarily by package type, such as PDIP, TSSOP, or MSOP, while maintaining identical core electrical specifications and functional capabilities.
