24AA515-I/P

Memory IC Overview

The Microchip Technology 24AA515-I/P is a 512 Kbit (64K x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a single supply voltage ranging from 1.7V to 5.5V and supports I²C™ compatible 2-Wire Serial Interface with maximum clock frequencies of 100 kHz at voltages below 2.5V and 400 kHz at voltages between 2.5V and 5.5V. The device features a 64-byte page write buffer, hardware write protection via the WP pin, and Schmitt trigger inputs for noise suppression. It is housed in an 8-lead PDIP package and rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Feature Summary

• Supports cascading up to four devices on the same data bus using configurable chip select inputs A0 and A1.
• Includes hardware write protection that inhibits write operations when the WP pin is tied to VCC.
• Features output slope control designed to eliminate ground bounce during operation.

Memory IC Applications

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

Memory IC Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and temperature range. Ensure the selected variant matches the required operating voltage conditions, particularly regarding clock frequency limitations at lower supply voltages. Confirm compliance with RoHS standards if applicable to the manufacturing batch.

Memory IC Selection Notes

Select this component for applications requiring non-volatile storage with I²C interface compatibility. Consider the 1.7V minimum operating voltage for low-power designs compared to other variants in the family. Evaluate the need for hardware write protection and the ability to expand address space by connecting multiple units on a shared bus.

Memory IC Part Context

This part belongs to the 24AA515/24LC515/24FC515 series of 512K I²C CMOS Serial EEPROMs. The 'I' designation indicates an industrial temperature range (-40°C to +85°C), while the '/P' suffix specifies the 8-lead plastic DIP package. Other series members differ in voltage ranges or clock speeds.

Memory IC Replacement Considerations

The 24LC515 and 24FC515 are functionally similar within the same datasheet but operate at different minimum voltages (2.5V) and clock speeds. Verify voltage compatibility before substitution.
