Flash Memory, IS25LP256D-JLLE, Integrated Silicon Solution INC
The IS25LP256D-JLLE 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 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 can also be configured to serve as multi-I/O (see pin descriptions). The device supports Dual and Quad I/O as well as standard, Dual Output, and Quad Output SPI. The IS25xP series of Flash adds support for DTR (Double Transfer Rate) commands that transfer addresses and read data on both edges of the clock. These transfer rates can outperform 16-bit Parallel Flash memories allowing for efficient memory access to support XIP (execute in place) operation.
