34AA04-I/P

Overview

The Microchip Technology 34AA04-I/P is a 4-kbit (512 x 8) serial electrically erasable programmable read-only memory (EEPROM). It utilizes a 2-Wire I2C interface with a maximum clock frequency of 1 MHz. The device operates within a supply voltage range of 1.7 V to 3.6 V and features an access time of 350 ns. It is housed in an 8-pin PDIP package designed for through-hole mounting. The component supports an industrial temperature range from -40°C to +85°C and offers a data retention period of 200 years.

Feature Summary

• Supports Serial Peripheral Interface (I2C) communication protocol via two-wire bus architecture
• Provides non-volatile data storage with long-term retention capabilities
• Compatible with low-voltage power supplies suitable for DDR4 SPD applications

Applications

• System Parameter Data (SPD) modules for DDR4 memory modules
• General-purpose serial EEPROM storage in embedded systems
• Configuration data storage in consumer electronics

Procurement Notes

Verify the specific suffix 'I/P' confirms the industrial temperature grade (-40°C to +85°C) and PDIP-8 through-hole package. Ensure the design requires the 1.7 V to 3.6 V operating voltage range, as this variant does not support higher voltages up to 5.5 V found in other series members. Confirm I2C address compatibility with the target system controller.

Selection Notes

Select this component when a through-hole DIP package is required for prototyping or specific board layouts. It is appropriate for designs needing 4-kbit capacity with standard I2C timing. Consider alternative packages like TSSOP or DFN if surface-mount technology is preferred or if space constraints exist on the printed circuit board.

Part Context

This part belongs to the 34AA04 family of serial EEPROMs manufactured by Microchip Technology. The family includes variants with different packaging options such as TSSOP and DFN, and tape-and-reel configurations. These devices are specifically optimized for use in System Parameter Data (SPD) applications within computer memory modules.

Replacement Considerations

The 34AA04-I/ST serves as a direct functional substitute with identical electrical specifications but utilizes a TSSOP-8 surface-mount package instead of the PDIP-8 form factor.
