DataFlash

Overview

Adesto Technologies DataFlash is a family of non-volatile memory devices with lower power requirements and smart features for higher system efficiency and lower system costs. The DataFlash E-series offers a range of features and options including industry-first capabilities such as wide VCC voltage (1.65V-3.6V) and an “ultra-deep power down” mode. The E-Series products also include new “smart”  features to improve system performance such as efficient “byte-write” that doesn’t require large block erase, and an industry-standard “erase-program-suspend-resume” command.

KEY FEATURES

  • Single 1.65-3.6V or 2.3V - 3.6V supply
  • 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.
