The IS25LQ040B/020B/010B/512B/025B (4M/2M/1M/512K/256Kbit) Serial Flash memory offers a storage solution with flexibility and performance in a simplified pin count package. ISSI’s “Industry Standard Serial Interface” is for systems that have limited space, pins, and power. The device 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 also serve as multi- function I/O pins in Dual and Quad modes (see pin descriptions). The IS25xQ series of Flash is ideal for code shadowing to RAM, execute in place (XIP) operations, and storing non-volatile data.
