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.
