Overview
The 34AA04-I/SN is a 4-kbit serial electrically erasable programmable read-only memory (EEPROM) manufactured by Microchip Technology. It features a 2-wire I2C interface with a maximum clock frequency of 1 MHz and an access time of 350 ns. The device operates within a supply voltage range of 1.7 V to 3.6 V and supports a storage organization of 512 x 8. It is housed in an 8-SOIC package, rated for industrial temperatures from -40°C to +85°C, and offers data retention of 200 years.
Feature Summary
- Supports high-speed I2C communication up to 1 MHz
- Designed specifically for SPD applications including DDR4
- Provides long-term non-volatile data retention
Applications
- System Parameter Data (SPD) modules
- DDR4 memory module configuration
- General-purpose serial EEPROM storage
Procurement Notes
Verify the specific suffix 'I/SN' corresponds to the industrial temperature range (-40°C to +85°C) and SOIC-8 package. Confirm that the 1.7V to 3.6V supply voltage requirement aligns with your system design, as this part does not support higher voltages like 5.5V found in other series variants. Ensure compatibility with I2C bus speeds up to 1 MHz.
Selection Notes
Select this component when designing systems requiring SPD functionality for DDR4 memory or general low-voltage serial storage. It is suitable for applications needing fast 1 MHz I2C access within a 3.6V maximum rail. Consider alternative packages like TDFN if space constraints exist, or different voltage ranges if operating above 3.6V.
Part Context
This part belongs to the 34AA04 family of serial EEPROMs optimized for System Parameter Data (SPD) applications. Unlike standard EEPROMs, these are tailored for memory module identification and configuration. The 'I' indicates industrial temperature rating, while 'SN' denotes the 8-pin SOIC surface-mount package.
Replacement Considerations
Public confirmed substitutes include 34AA04-I/ST (TSSOP-8 package) and 34AA04T-I/MNY (TDFN-8 package). Verify pinout compatibility and voltage specifications before substitution.
