Dual / Quad SPI Memory

Universal and Expandable

  • Ultra-low Energy, Low Power
  • Fast Page Erase
  • 7nA Sleep
  • Battery Monitor
  • Security

Our Dual / Quad products, including our new Ultra-low Energy AT25EU and FusionHD™ devices, are designed with compatibility in mind. They feature industry standard features and pin outs that can work in any new or pre-existing design. But we know that great systems need more. This is why we offer product lines with a wealth of advanced features such as 7nA sleep, faster page erase for ultimate energy efficiency , hi-reliability, hi-temp and comprehensive security features.

Roadamap of AT25DF321A-SH-T

Posted bysanjaykumarsin…10 points 1 reply

Can you please suggest the Roadmap for AT25DF321A-SH-T ?

We are planning to use it for a new custom board design.

Kindly suggest whether AT25DF321A-SH-T is recommended for new designs.

Regard

The DF321A is an older Flash device but we have no plans to EoL this product. That said, we might suggest you consider the AT25FF321A as a more modern alternative for a new design. This part is included in our longevity program and is on a more competitive process. This is a wide Vcc device with an Ultra Deep Power Down current consumption of ~7nA. If you must have the lowest price then there is the AT25SF321B but this part is NOT included in our longevity program and may be subject to change with only a short notice period. If power consumption is of interest then please also consider the AT25XE321D part which will offer you extra features to help minimise power consumption such as the 7nA UDPD, Page Erase, a READ/WRITE buffer and active interrupt. The AT25XE parts are also part of our longevity program.

Have a look throughMicrosoft Word - Adesto 32Mbit Products Overview-AN201-A2-2020-05-21.docx (dialog-semiconductor.com)which will detail the differences but all the basic commands are the same and the pin outs all conform to standard 25xxx configuration.
