GENERAL DESCRIPTION
The IS25WD020/040 are 2 Mbit / 4Mbit Serial Peripheral Interface (SPI) Flash memories, providing single- or
dual-output. The devices are designed to support a 30 MHz fclock rate in normal read mode, and 80 MHz in fast
read, the fastest in the industry. The devices use a single low voltage power supply, wide operating voltage
ranging from 1.65 Volt to 1.95 Volt, to perform read, erase and program operations. The devices can be
programmed in standard EPROM programmers.
The IS25WD020/040 are accessed through a 4-wire SPI Interface consisting of Serial Data Input/Output (SlO),
Serial Data Output (SO), Serial Clock (SCK), and Chip Enable (CE#) pins. They comply with all recognized
command codes and operations. The dual-output fast read operation provides and effective serial data rate of
160MHz.
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 IS25WD020/040 are manufactured on pFLASH™’s advanced non-volatile technology. The devices are
offered in 8-pin SOIC 208mil, 8-pin SOIC 150mil, 8-pin VVSOP 150mil and 8-pin WSON. The devices operate at
wide temperatures between -40°C to +105°C.
