GENERAL DESCRIPTION

The IS25LE02GG and IS25WE02GG 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 133MHz allow for equivalent clock rates of up to 532MHz (133MHz x 4) which equates to 83Mbytes/s of

data throughput. 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.

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.

ECC Protection (1-bit Error Correction) applies per every 16-byte (128-bit) to maximize reliability.

When ECC is ON, due to a partial programming restriction, it is recommended to program in

multiples of 16-byte (ECC Chunk size) data within 256byte page buffer.

Customer can program a byte or word within a chunk, but customer cannot do another partial

programming within a chunk without ERASE.
