GENERAL DESCRIPTION

The IS25LQ040 is 4 Mbit Serial Peripheral Interface (SPI) Flash memories, providing single-, dual or quad-

output. The devices are designed to support a 33 MHz fclock rate in normal read mode, and 104 MHz in fast

read (Quad output is 100MHz), the fastest in the industry. The devices use a single low voltage power supply,

ranging from 2.3 Volt to 3.6 Volt, to perform read, erase and program operations. The devices can be

programmed in standard EPROM programmers.

The IS25LQ040 are accessed through a 4-wire SPI Interface consisting of Serial Data Input/Output (Sl), Serial

Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins. The devices support page program mode,

where 1 to 256 bytes data can be programmed into the memory in one program operation. These devices are

divided into uniform 4 KByte sectors or uniform 64 KByte blocks.

The IS25LQ040 are offered in 8-pin SOIC 208mil, 8-pin PDIP, 8-pin VVSOP and 8-contact WSON.
