GENERAL DESCRIPTION

The IS25LQ025/512/010/020/040B (256K/512K/1M/2M/4Mbit) 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 IS25LQ025/512/010/020/040B 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.

The memory array is organized into programmable pages of 256-bytes each. The IS25LQ025/512/010/020/040B

supports page program mode where 1 to 256 bytes of data can be programmed into the memory with one command.

Pages can be erased in groups of 4Kbyte sectors, 32Kbyte blocks, 64Kbyte blocks, and/or the entire chip. The uniform

sectors and blocks allow greater flexibility for a variety of applications requiring solid data retention.

The device supports the standard Serial Peripheral Interface (SPI), Dual/Quad output (SPI), and Dual/Quad I/O (SPI).

Clock frequencies of up to 104MHz for all read modes allow for equivalent clock rates of up to 416MHz (104MHz x 4)

allowing up to 52MBytes/S of throughput. These transfer rates can outperform 16-bit Parallel Flash memories allowing

for efficient memory access for a XIP (execute in place) operation. The IS25LQ025/512/010/020/040B is manufactured

using industry leading non-volatile memory technology and offered in industry standard lead-free packages. See

Ordering Information for the density and package combinations available.
