The octaflash series can be divided into the following types: MX25 series : Serial NOR Flash. LM/UM series : Up to 250MHz clock frequency with both DTR/STR operation. LW/UW series : Support simultaneous Read-while-Write operation in multiple bank architecture. Read-while-write feature which means read data one bank while another bank is programing or erasing. MX25LW : 3.0V Octal I/O with Read-while-Write MX25UW : 1.8V Octal I/O with Read-while-Write MX25LM : 3.0V Octal I/O Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8729/MX25LM51245G= ,%203V,%20512Mb,%20v1.1.pdf MX25UM : 1.8V Octal I/O Link: https://www.mxic.com.tw/Lists/Datasheet/Attachments/8967/MX25UM51245G= ,%201.8V,%20512Mb,%20v1.5.pdf Those flash have been tested on Xilinx Zynq-picozed board using MXIC SPI controller.
