The Micron MT25QU256ABA8E55-0SIT TR is a 256 Mbit NOR Flash memory organized as 32M x 8 bits, accessed through a standard SPI interface. Clocked at 133 MHz, it operates from 1.7 V to 2 V. The 23-XFWLBGA package keeps the footprint compact.
At 133 MHz, the SPI clock delivers a raw bit rate of 133 Mbps in single-I/O mode. This clock rate matches the 256 Mbit density siblings.
Yes, the supply voltage range is 1.7 V to 2 V, so 1.8 V nominal operation is within spec.
The MT25QU256ABA1EW7-0SIT is a functional equivalent with the same density, speed, and 1.8 V supply, but packaged in bulk rather than Tape & Reel. For a 2.7 V supply system, the MT25QL256ABA1EW9-0SIT TR is the QL counterpart.
The MT25QU256ABA8E55-0SIT TR is the Tape & Reel packaged version of the base MT25QU256ABA8E55-0SIT die. The silicon and electrical specifications are identical; only the shipping format differs.
