34AA04T-E/MUY

Overview

The Microchip Technology 34AA04T-E/MUY is a 4-kbit (512 x 8) serial electrically erasable programmable read-only memory (EEPROM) designed for low-voltage applications. It operates within a supply voltage range of 1.7 V to 3.6 V and supports I2C interface communication with a maximum clock frequency of 1 MHz. The device features a UDFN-EP package with 8 pins, ensuring reliable surface-mount integration. It offers a data retention period of 200 years and supports industrial temperature ranges from -40°C to +85°C.

Feature Summary

• Supports software write-protect functionality to prevent accidental data modification
• Compatible with standard two-wire I2C bus protocol for efficient serial communication
• Provides high endurance and long-term data retention capabilities

Applications

• DDR4 SPD (Serial Presence Detect) modules
• Consumer electronics requiring non-volatile configuration storage
• Industrial control systems needing reliable parameter retention

Procurement Notes

Verify the specific suffix MUY confirms the UDFN-EP package type and industrial temperature grade (-40°C to +85°C). Ensure compatibility with 1.7V to 3.6V supply rails before integration. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor declarations to meet regulatory requirements for electronic assemblies.

Selection Notes

Select this component when a compact 4-kbit EEPROM is required for I2C-based systems operating at low voltages. The UDFN-EP package offers a small footprint suitable for space-constrained designs. Verify that the 1 MHz clock speed meets system timing requirements and that the industrial temperature range aligns with the operational environment specifications.

Part Context

This part belongs to the 34AA04 series of serial EEPROMs from Microchip Technology. These devices are optimized for use in memory modules and embedded systems where small capacity and low power consumption are critical. The series typically includes variants with different packaging options and temperature grades to suit diverse manufacturing needs.

Replacement Considerations

Check for direct substitutes such as the 34AA04T-I/MUY for commercial temperature grade applications. Cross-reference pinouts and electrical characteristics with other 4-kbit I2C EEPROMs if alternative sourcing is necessary.
