24AA52T-I/MNY

Memory IC Overview

The Microchip 24AA52T-I/MNY is a 2 Kbit Electrically Erasable PROM organized as one block of 256 bytes (256 x 8). It operates on a single supply voltage ranging from 1.8V to 5.5V and supports I2C compatible 2-Wire Serial Interface Bus communication with a maximum clock frequency of 400 kHz. The device features software write protection for the lower 128 bytes and hardware write protection for the entire array via an external pin. It includes Schmitt trigger inputs, output slope control, and ESD protection exceeding 4,000V. The component is housed in an 8-lead TDFN package and is rated for industrial temperature ranges from -40°C to +85°C.

Memory IC Procurement Notes

Verify that the ordering suffix matches the required package type and temperature range specifications. Confirm the device revision aligns with current datasheet documentation. Ensure the supplier provides traceability information consistent with Microchip standards. Check for RoHS compliance status if required by specific manufacturing regulations. Validate the authenticity of the component through authorized distribution channels.

Memory IC Selection Notes

Select this component when a 2 Kbit EEPROM with I2C interface is required for low-voltage applications. Consider the 24AA52 series for designs needing flexible write protection options. Evaluate the TDFN package suitability for space-constrained surface mount layouts. Ensure the operating voltage range of 1.8V to 5.5V matches the system power supply constraints.

Memory IC Part Context

This part belongs to the 24AA52/24LCS52 family of 2Kbit Serial EEPROMs manufactured by Microchip Technology. The family offers various package options including PDIP, SOIC, TSSOP, MSOP, DFN, and TDFN. The 'I' designation indicates an industrial temperature range rating. The 'T' suffix typically denotes tape and reel packaging, while 'MNY' specifies the specific TDFN package variant.

Memory IC Replacement Considerations

Direct substitutes within the same family include other 24AA52 variants with different package styles such as 24AA52-I/MS or 24AA52-I/ST. Cross-reference with 24LCS52 models if higher clock speeds at lower voltages are not critical. Verify pinout compatibility before substituting packages like DFN for TDFN.
