34AA04T-I/MNY

Overview

The 34AA04T-I/MNY is a 4-kbit (512 x 8) serial EEPROM manufactured by Microchip Technology. It utilizes an I²C interface with a maximum clock frequency of 1 MHz and features a fast page write capability with a 5 ms cycle time. The device operates within a supply voltage range of 1.7 V to 3.6 V, ensuring compatibility with low-voltage systems. It offers a typical access time of 350 ns and supports data retention for up to 200 years. The component is housed in an 8-TDFN (2x3) surface-mount package and is rated for industrial operating temperatures from -40°C to +85°C.

Feature Summary

• Supports high-speed I²C communication with a 1 MHz clock rate
• Provides non-volatile storage with extended 200-year data retention
• Operates reliably across the full industrial temperature range

Applications

• Serial Peripheral Data (SPD) implementation for DDR4 memory modules
• Storage of system configuration parameters in embedded controllers
• Data logging applications requiring long-term non-volatile retention

Procurement Notes

Verify the specific suffix 'I/MNY' against official Microchip documentation to confirm the exact package type, temperature grade, and RoHS compliance status. Ensure that the 1.7 V to 3.6 V supply voltage range aligns with your system's power rails. Confirm that the 8-TDFN footprint matches your PCB layout requirements before finalizing procurement.

Selection Notes

Select this component when a compact surface-mount solution is required for small-scale non-volatile data storage. It is suitable for designs needing fast I²C bus speeds and low power consumption. Consider the 512-byte organization for simple parameter storage. Verify that the 3.6 V maximum voltage rating does not exceed the logic levels used in the target application circuit.

Part Context

This part belongs to the 34AA series of serial EEPROMs designed specifically for SPD applications in computer memory systems. It complements other variants like the 34AA02 and 34AA08, offering a mid-range capacity option. The TDFN packaging allows for space-constrained designs common in modern mobile and desktop computing platforms.

Replacement Considerations

Public confirmed substitute part numbers include 24AA04HT-I/MNY and 24AA04T-I/MNY.
