128Mbit, 3V SPI Serial Flash Memory with Dual I/O and Quad I/O Support

Order Now

Overview

The AT25QF128A is a member of our standard class code and data storage solutions designed for 3V systems in which program code is shadowed from Flash memory into embedded or external RAM for execution.

The architecture includes erase block sizes optimized to meet the needs of today's code and data storage applications, and three security register pages for unique device serialization, system-level Electronic Serial Number (ESN) storage, locked key storage, etc.

  • Universally compatible pinout and command set
  • Standard block architecture
  • Supports Dual I/O, Quad I/O and XiP operation
  • Quad enabled at the factory
  • Continuous read, wrap, and burst modes for XiP

  1. Issue: FLASH Device (AT25QF128A-MHB-T), Unable to read & write over 64KB of memory

    Hi Team, We are using AT25QF128A-MHB-T for one of our product. We are facing read & write issues with the FLASH device. While writing or reading the memory device more than 64KB, it was not responding. We are writing the data & reading back with STM Microcontroller. Request ...

  2. Serial NOR Flash pause read's by holding SCLK low

    Hello, during a burst read, if i hold SCLK low, and then re-start clocking 'x cycles' later will that cause any issues with auto-reading out the entire memory array using Quad SPI mode?
