ISSI IS25LP512MJ & IS25WP512MJ Flash Memory Devices

ISSI IS25LP512MJ and IS25WP512MJ Flash Memory Devices are versatile storage solutions designed for systems that require limited space, low pin count, and low power consumption. These devices are accessed through a 4-wire SPI interface. The interface includes a Serial Data Input (SI), Serial Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins. The IS25LP512MJ and IS25WP512MJ Flash memory devices support Double Transfer Rate (DTR) commands that transfer addresses and read data on both edges of the clock. These devices feature 80MHz normal read, up to 166MHz fast read, 1μA deep power down, 6μA standby current, and 8mA active read current. The IS25LP512MJ and IS25WP512MJ Flash memory devices offer more than 20 years of data retention.
