GENERAL DESCRIPTION
The IS25LQ032B/016B/080B (32/16/8M-bit) 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.
The memory array is organized into programmable pages of 256-bytes each. The device 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)
which equates 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 device is manufactured using industry
leading non-volatile memory technology and offered in industry standard lead-free packages. See Ordering
