Adesto Technologies 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 series Serial Flash incorporates a uniform block-erase (4-KBytes, 32-KBytes, and 64-KBytes) architecture to provide a high level of flexibility for a wide variety of code storage applications. AT25D series devices feature advanced security and protection functions to prevent critical code blocks from being erroneously or maliciously altered. AT25D series devices are pin-compatible with Atmel's Serial EEPROMs, giving developers the flexibility to increase memory size without changing the board layout.
Adesto's AT25SF family includes 4, 8, 16 and 32‐Mbit density multi‐I/O products designed for higher density devices. The AT25SF series incorporates a uniform, block-erase architecture to provide a high level of flexibility for a wide variety of code storage applications. These SPI‐compatible 2.5V to 3.6V products feature up to 104MHz operating speed and fast program and erase times. The devices also include security features such as a programmable security register and hardware controlled locking of protected blocks. The AT25SF family is ideal for high‐volume, consumer‐based applications in which program code is shadowed from flash into embedded or external RAM for execution.
