DataFlash™

SPI Memory

Octal Dual/Quad DataFlash™ EEPROM Wafer/KGD CBRAM Technology

DataFlash™ SPI Memory

Most Efficient Flash Memory for Data Logging.

  • Byte / Page Programming
  • Fast Page Erase
  • Low Power Modes
  • Power Fail Protection
  • Data Integrity & Security

DataFlash’s advanced dual SRAM buffer architecture makes it the most efficient memory for data logging. It also incorporates a suite of advanced features that save system power, reduce processtor overhead, simplify software development, and provide comprehensive data security and integrity options.

Key Features

  • Wide Vcc
  • Dual SRAM buffer
  • Low power operation extends system battery life
  • Byte-write provides Serial EEPROM functionality in a Serial NOR Flash device
  • Ultra-deep power down operates at >400nA
  • Extended Vcc operation allows the system memory to operate over the entire voltage range
  • Comprehensive security and unique ID features protect the device from outside tampering

DataFlash® and Serial Flash BGA Package

525 kB • March 2014

As devices have been brought to End of Life status, demand for the 24Ball BGA has declined and Adesto will only support the 9Ball BGA for the new replacement products. The 9Ball BGA (Package Code ‘CCU’), has been designed to be a direct replacement for the obsolete 24Ball BGA (Package Code ‘CU’) in all respects. The CCU package matches the ball out of the CCU package exactly and is totally interchangeable for a Dataflash or Serial Flash device.

AVR116: Wear Leveling on DataFlash

629 kB • July 2012

This application note describes the use of the Flash Translation Layer (FTL) interface. It describes the features, structure and interface of the FTL library, and how to use this library. Flash memory has a limited program/erase lifecycle and programming and erasing the same block many times will result in bad blocks and shortened flash memory life. The intermediate software layer, FTL, addresses this issue.

DataFlash® and Serial Flash BGA Package

525 kB • March 2014

As devices have been brought to End of Life status, demand for the 24Ball BGA has declined and Adesto will only support the 9Ball BGA for the new replacement products. The 9Ball BGA (Package Code ‘CCU’), has been designed to be a direct replacement for the obsolete 24Ball BGA (Package Code ‘CU’) in all respects. The CCU package matches the ball out of the CCU package exactly and is totally interchangeable for a Dataflash or Serial Flash device.

AVR116: Wear Leveling on DataFlash

629 kB • July 2012

This application note describes the use of the Flash Translation Layer (FTL) interface. It describes the features, structure and interface of the FTL library, and how to use this library. Flash memory has a limited program/erase lifecycle and programming and erasing the same block many times will result in bad blocks and shortened flash memory life. The intermediate software layer, FTL, addresses this issue.
