24LC512-I/SN

Memory IC Overview

The Microchip Technology 24LC512-I/SN is a 512 Kbit Electrically Erasable PROM organized as 64K x 8-bit memory. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device features an access time of 900 ns and supports I²C two-wire serial interface communication. It includes hardware write protection, Schmitt trigger inputs for noise suppression, and output slope control. The component is housed in an 8-lead SOIC package and functions within an industrial temperature range of -40°C to +85°C.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using configurable chip select inputs.
• Includes a 128-byte page write buffer for efficient data storage operations.
• Features hardware write protection via the WP pin to inhibit array writes.

Memory IC Applications

• Embedded systems requiring non-volatile parameter storage
• Industrial equipment needing reliable data retention
• Consumer electronics utilizing I²C serial interfaces

Memory IC Procurement Notes

Verify that the ordering suffix 'I' corresponds to the Industrial temperature grade (-40°C to +85°C) and 'SN' indicates the 8-lead SOIC package. Confirm the specific datasheet revision matches the required electrical characteristics. Ensure compatibility with the host system's I²C voltage levels and pull-up resistor requirements before finalizing procurement.

Memory IC Selection Notes

Select this component when a 512 Kbit EEPROM capacity is required with standard I²C connectivity. It is suitable for applications operating between 2.5V and 5.5V where industrial temperature stability is necessary. Consider alternatives like the 24AA512 or 24FC512 if lower voltage operation (1.7V) or higher clock speeds (1 MHz) are needed.

Memory IC Part Context

This part belongs to the 24XX512 family of serial EEPROMs from Microchip Technology. It shares functional similarities with the 24AA512 and 24FC512 but differs in voltage range and speed specifications. The 24LC512 specifically targets applications requiring 2.5V minimum operation and 400 kHz clock compatibility.

Memory IC Replacement Considerations

The 24LC512T-I/SN serves as a tape-and-reel replacement for the tube-packaged 24LC512-I/SN. Other variants within the 24LC512 series may be considered if different packaging options are required.
