24LC515T-I/SM

Memory IC Overview

The Microchip Technology 24LC515T-I/SM is a 512K-bit (64K x 8) Serial Electrically Erasable PROM featuring an I²C-compatible interface. It operates on a single supply voltage ranging from 2.5V to 5.5V and supports clock frequencies up to 400 kHz. The device utilizes low-power CMOS technology, offering typical active current of 500 µA and standby current of 100 nA. 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 four devices on the same data bus using configurable chip select inputs.
• Features a 64-byte page write buffer to optimize data transfer efficiency.
• Includes hardware write protection via the WP pin to inhibit array writes when tied high.

Memory IC Applications

• Personal communications systems
• Data acquisition applications
• Advanced low-power electronic designs

Memory IC Procurement Notes

Verify that the ordering suffix 'T' corresponds to the tape and reel packaging format specified by the manufacturer. Confirm the industrial temperature range rating (-40°C to +85°C) aligns with operational requirements. Ensure the SOIJ package dimensions match the target PCB footprint constraints.

Memory IC Selection Notes

Select this component for applications requiring non-volatile storage with I²C connectivity. Note that the A2 pin must be hard-wired to VCC for operation. Consider the 24AA515 if operation below 2.5V is required, or the 24FC515 for higher speed interfaces up to 1 MHz.

Memory IC Part Context

This part belongs to the 24XX515 family of serial EEPROMs manufactured by Microchip Technology. It shares functional similarities with the 24AA515 and 24FC515, differing primarily in operating voltage ranges and maximum clock frequencies. The T suffix indicates a specific packaging variant within the standard SOIJ form factor.

Memory IC Replacement Considerations

Public confirmed substitute part numbers include 24LC515-I/P and 24LC515-I/SN. Verify compatibility regarding voltage ranges and package types before substitution.
