Fusion Enhanced Serial Flash

Renesas / Dialog Serial Flash devices incorporate some of the industry's most advanced and flexible features, many of which are unparalleled by other solutions on the market. The Adesto Serial Flash family of products is based on proven and robust NOR Flash technology. Adesto Technologies AT25D Serial Flash incorporates a uniform block-erase (4-KBytes, 32-KBytes, and 64-KBytes) architecture to provide flexibility for a variety of code storage applications. AT25D devices feature advanced security and protection functions to prevent critical code blocks from being erroneously or maliciously altered. AT25D devices are pin-compatible with Atmel's Serial EEPROMs, giving developers the flexibility to increase memory size without changing the board layout.
