24LC512T-I/SM

Memory IC Overview

The Microchip Technology 24LC512T-I/SM is a 512 Kbit (64K x 8) serial electrically erasable PROM featuring an I2C compatible two-wire interface. It operates on a single supply voltage ranging from 2.5V to 5.5V with a maximum clock frequency of 400 kHz. The device supports page writes up to 128 bytes and includes hardware write protection via the WP pin. It is housed in an 8-lead SOIJ 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 a single bus using configurable chip select inputs.
• Includes Schmitt trigger inputs for noise suppression and output slope control to eliminate ground bounce.
• Features a 128-byte page write buffer for efficient data transfer operations.

Memory IC Applications

• Personal communications equipment requiring non-volatile storage
• Data acquisition systems needing parameter retention
• Industrial controllers storing calibration data

Memory IC Procurement Notes

Verify that the ordering suffix corresponds to the specific SOIJ package type required for your PCB layout. Confirm the 'I' designation matches the necessary industrial temperature range specifications for your operational environment. Ensure the tape and reel packaging aligns with your automated assembly capabilities.

Memory IC Selection Notes

Select this component when a 512 Kbit capacity is required alongside standard I2C compatibility. It is suitable for designs operating between 2.5V and 5.5V where low standby current is beneficial. Consider the SOIJ package dimensions if space constraints preclude larger packages like SOIC or TSSOP.

Memory IC Part Context

This part belongs to the 24XX512 family, which also includes the 24AA512 and 24FC512 variants. These devices share similar functional architectures but differ in supply voltage ranges and maximum clock frequencies. The 24LC512 specifically targets applications requiring operation down to 2.5V.
