24LC512-E/SN16KVAO

Memory IC Overview

The Microchip Technology 24LC512-E/SN is a 512 Kbit Electrically Erasable PROM organized as one block of 64K x 8-bit memory. It features a two-wire serial interface compatible with I2C protocols. The device operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz. It includes hardware write protection, Schmitt trigger inputs for noise suppression, and output slope control to eliminate ground bounce.

Memory IC Feature Summary

• Supports cascading up to eight devices on the same bus using configurable chip address inputs.
• Features hardware write protection controlled by the WP pin to inhibit array writes.
• Includes internal self-timed erase/write cycles with automatic page buffer management.

Memory IC Applications

• Industrial embedded systems requiring non-volatile data storage
• Automotive electronic modules utilizing AEC-Q100 qualified components
• Consumer electronics needing reliable low-power memory solutions

Memory IC Procurement Notes

Verify that the ordering suffix matches the required temperature grade (E for Extended) and package type (SN for SOIC). Confirm RoHS compliance status and ensure the specific revision level aligns with your design requirements. Cross-reference the manufacturer part number with official datasheets to validate electrical characteristics before finalizing procurement orders.

Memory IC Selection Notes

Select this component when an extended industrial temperature range (-40°C to +125°C) is required alongside standard I2C compatibility. Ensure the system voltage remains within the 2.5V to 5.5V operational window. Consider the 128-byte page write buffer size for efficient data throughput in applications involving frequent small data updates.

Memory IC Part Context

This device belongs to the 24XX512 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA512 and 24FC512 models but differs in minimum operating voltage and maximum clock frequency specifications. The family utilizes a common pinout and protocol structure across various package options.

Memory IC Replacement Considerations

Direct substitutes include other variants within the 24LC512 series such as 24LC512-I/SN for industrial temperature grades or different package types like 24LC512T-E/SM. Verify voltage ranges and speed capabilities when considering cross-family replacements like 24AA512 or 24FC512.

Memory IC FAQ

How does the Write-Protect (WP) pin function?

When tied to VCC, the WP pin inhibits all write operations to the array while allowing read operations to proceed normally. Tying it to VSS enables write access.

What is the maximum clock frequency supported?

The device supports a maximum clock frequency of 400 kHz when the supply voltage is between 2.5V and 5.5V.
