Adesto Technologies DataFlash

Adesto Technologies DataFlash devices are feature-rich, page erase (as small as 256 bytes) SPI-compatible Serial Flash with advanced protection and security features. These Adesto Technologies devices provide developers with the most flexible, easy-to-use Serial Flash solution on the market to address virtually any application. Dual-I/O and Quad-I/O interface options provide the ability to double and quadruple read throughputs. AT45DB series DataFlash devices provide system developers with an extremely flexible solution by utilizing a page-erase architecture to allow the smallest amount of data (as little as 256 bytes) to be erased compared to any other Flash solution.

AT45DBxxx Features
  • 1-Mbit to 64-Mbit densities
  • Small page array architecture
  • Individually erasable pages of 256/264, 512/528, or 1024/1056 bytes each
  • Dual on-chip, independent SRAM buffers
  • SRAM buffer size equal to memory page size
  • Command-rich instruction set
  • Enhanced low-power read
  • Zero-power shutdown options
  • Software reset capability
AT45DBxxx Advantages
  • Granular page sizes offer greater flexibility than block erase architectures
  • Command-rich instruction set allows for a smaller software footprint and lower CPU overhead
  • Enhanced permanent and nonvolatile sector protection schemes simplify your system safeguards
  • Enhanced nonvolatile sector protection options simplify system protection
  • SRAM buffers and byte write capability allow true E²PROM emulation
  • SRAM buffers can be used as an additional system resource (extra SRAM)
