Memory IC Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature grade (-40°C to +125°C) and 'T' denotes tape-and-reel packaging. Confirm the 1 MHz speed class matches system requirements. Ensure the 8-TSSOP footprint aligns with PCB layout constraints before finalizing orders.

Memory IC Selection Notes

Select this component when high-speed I2C access is required alongside wide voltage tolerance. The extended temperature rating makes it suitable for automotive or industrial applications where standard commercial grades may fail. Compare against the 24AA04H series if lower power consumption at slower speeds is acceptable.

Memory IC Part Context

This part belongs to the 24AA04 family of 4-kbit EEPROMs manufactured by Microchip Technology. It shares architectural similarities with other I2C-compatible devices in the lineup but distinguishes itself through its specific speed grade and extended temperature operational capabilities defined by its model suffixes.

Memory IC Replacement Considerations

Direct substitutes include the 24AA044-E/ST (tube packaging) or the 24AA04HT-I/ST (industrial temperature). Verify pinout compatibility and ensure the replacement meets the same 1 MHz clock and voltage specifications.
