ISSI IS25WP512M & IS25LP512M Serial NOR Flash

ISSI IS25WP512M & IS25LP512M Serial NOR Flash is a versatile storage solution with high flexibility and performance in a simplified pin count package. The device is for systems that require limited space, a low pin count, and low power consumption. It is accessed through a 4-wire SPI Interface consisting of a Serial Data Input (SI), Serial Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins, which can also be configured to serve as multi-I/O. The device supports Dual and Quad I/O as well as standard, Dual Output, and Quad Output SPI. Clock frequencies of up to 133MHz allow for equivalent clock rates of up to 532MHz (133MHz x 4), which equates to 66.5Mbytes/s of data throughput. The memory array is organized into programmable pages of 256/512 bytes.
