Renesas / Dialog AT25FF321A 32Mbit SPI Serial Flash Memory

Renesas / Dialog AT25FF321A 32Mbit SPI Serial Flash Memory is developed for use in a wide variety of high-volume consumer and connected applications. The AT25FF321A serial interface Flash memory device is optimized for low-energy applications. The device operates using modem Lithium battery technology over a wide input voltage range of 1.65V to 3.6V.

The Renesas / Dialog AT25FF321A 32Mbit SPI Serial Flash Memory is well suited for systems where program code is executed in place (XiP) or is shadowed from Flash memory into embedded or external RAM (code shadow). This execution allows small amounts of data to be stored and updated locally in the Flash memory.

Features

  • Universally compatible pinout and command set
  • Low Sleep power for bootloader tasks
  • Supports Dual IO, Quad IO, and XiP operation
  • Continuous read, wrap, and burst modes for XiP

Applications

  • Standard class code and data storage systems
  • Battery-powered designs
