Frequently asked questions
What is the supply voltage range for MT25QU128ABA1EW9-0SIT?
The supply voltage range is 1.7 V to 2 V, making it a 1.8 V nominal part. It is not compatible with 3.3 V SPI buses without level translation.
Does MT25QU128ABA1EW9-0SIT support Quad SPI?
Yes, the memory interface is SPI with Quad I/O support, allowing four data lines for higher throughput at the 133 MHz clock rate.
What is the closest functional equivalent to MT25QU128ABA1EW9-0SIT?
The MT25QU128ABA8E54-0SIT TR is the same 128 Mbit NOR Flash die in Tape & Reel packaging. For a 3.3 V supply, the MT25QL128ABA1EW9-0SIT TR uses the same package and pinout but operates at 2.7 V to 3.6 V.
