IS25LP256E-THLA3-TR Features

Overview

The IS25LP256E and IS25WP256E 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. Clock frequencies of up to 166MHz allow for equivalent clock rates of up to 664MHz (166MHz x 4) which equates to 83Mbytes/s of data throughput. The IS25xE 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. Initial state of the memory array is erased (all bits are set to 1) when shipped from the factory. QPI (Quad Peripheral Interface) supports 2-cycle instruction further reducing instruction times. Pages can be erased in groups of 4Kbyte sectors, 32Kbyte blocks, 64K/256Kbyte blocks, and/or the entire chip. The uniform sector and block architecture allows for a high degree of flexibility so that the device can be utilized for a broad variety of applications requiring solid data retention.
