Clocked at 133 MHz, it operates from 1.7 V to 2 V. Operating temperature spans -40°C to 85°C. The 23-XFWLBGA package keeps the footprint compact. ## 133 MHz SPI — what it means for the bus 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.","metaTitle":"Micron MT25QU256ABA8E55-0SIT TR 256Mb NOR Flash, 133 MHz SPI, 1.8V","metaDescription":"Micron MT25QU256ABA8E55-0SIT TR 256Mbit NOR Flash SPI, 133 MHz clock, 1.7V-2V supply, -40°C to 85°C, 23-XFWLBGA.
