IS25WD020 - 2 Mbit / 4 Mbit Single Operating Voltage Serial Flash Memory

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.

Key Features

  • Single Power Supply Operation - Low voltage range: 1.65 V.
  • 1.95 V.
  • Memory Organization - IS25WD020: 256K x 8 (2 Mbit) - IS25WD040: 512K x 8 (4 Mbit).
  • Cost Effective Sector/Block Architecture - 2Mb : Uniform 4KByte sectors / Four uniform 64KByte blocks - 4Mb : Uniform 4KByte sectors / Eight uniform 64KByte blocks.
  • Serial Peripheral Interface (SPI) Compatible - Supports single- or dual-output - Supports SPI Modes 0 and 3 - Maximum 30 MHz clock rate fo.
