34AA04T-I/ST

Overview

The Microchip Technology 34AA04T-I/ST is a 4-kbit (512 x 8) serial electrically erasable programmable read-only memory (EEPROM). It operates on a two-wire I2C interface with a maximum clock frequency of 1 MHz. The device supports a supply voltage range from 1.7 V to 3.6 V and features an access time of 350 ns. It is housed in an 8-lead TSSOP package designed for surface mount technology. The component ensures data retention for up to 200 years and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Supports Serial Peripheral Data (SPD) specifications for DDR4 applications
• Utilizes a standard two-wire I2C compatible serial interface
• Provides high endurance with extended data retention capabilities

Applications

• DDR4 SPD storage
• Industrial data logging
• Consumer electronics configuration storage

Procurement Notes

Verify the specific suffix 'I/ST' against the official datasheet to confirm the industrial temperature grade (-40°C to +85°C) and tape-and-reel packaging format. Ensure the system design accommodates the 1.7 V to 3.6 V operating voltage range and that the I2C bus timing aligns with the specified 1 MHz maximum clock frequency requirements.

Selection Notes

Select this component when a low-voltage, small-footprint EEPROM is required for storing system configuration data or SPD information. The TSSOP-8 package offers a compact solution for space-constrained designs. Consider the 1 MHz interface speed and 350 ns access time for systems requiring moderate data throughput within the specified industrial temperature environment.

Part Context

This part belongs to the 34AA04 series of serial EEPROMs manufactured by Microchip Technology. These devices are specifically engineered for applications requiring non-volatile memory with low power consumption and small physical size. The series is commonly utilized in digital consumer products and industrial systems where reliable data storage is critical.

Replacement Considerations

Check for direct pin-compatible alternatives within the same manufacturer's portfolio that match the 512 x 8 organization and I2C interface. Verify that any substitute maintains the same voltage range and package dimensions.
