GENERAL DESCRIPTION
The IS25WP128/064/032 Serial Flash memory offers a versatile storage solution with high flexibility and performance in a simplified pin count package. ISSI’s “Industry Standard Serial Interface” Flash is for systems that require limited space, a low pin count, and low power consumption. The IS25WP128/064/032 is accessed through a 4-wire SPI Interface consisting of a Serial Data Input (Sl), Serial Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins, which can also be configured to serve as multi-I/O (see pin descriptions).
