IS25LQ020 - 4Mbit Single Operating Voltage Serial Flash Memory

Download the IS25LQ020 datasheet PDF. This datasheet also covers the IS25LQ040 variant, as both devices belong to the same 4mbit single operating voltage serial flash memory family and are provided as variant models within a single manufacturer datasheet.

General Description

The IS25LQ020/040 is 2 Mbit / 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.

Key Features

  • Single Power Supply Operation - Low voltage range: 2.3 V - 3.6 V.
  • Memory Organization - IS25LQ020: 256K x 8 (2 Mbit) - IS25LQ040: 512K x 8 (4 Mbit).
  • Cost Effective Sector/Block Architecture - 2Mb / 4Mb : Uniform 4KByte sectors / sixteen uniform 64KByte blocks.
  • Serial Peripheral Interface (SPI) Compatible - Supports single-, dual- or quad-output - Supports SPI Modes 0 and 3 - Maximum 33 MHz clock rate for normal read - Maximum 104 MHz clock rate for fast read.
