2.5 to 3.6 V Block Erase Serial Flash


SPI serial Flash memory with dual and quad-I/O support from Adesto

SPI-compatible block erase serial Flash designed specifically for high-volume, consumer-based applications in which program code is shadowed from Flash into embedded or external RAM for execution. Block erase sizes of 4 KB, 32 KB, and 64 KB provide flexibility for code and data management while advanced protection and security features further enhance code and data stability. The 2.5 V to 3.6 V products feature up to 104 MHz operating speed and fast program and erase times. For improved performance, increased read throughputs can be attained by using the Dual or quad-I/O modes of the devices.

Features
  • Flexible storage for boot code, program code, vital preference data or logged data
  • Industry-standard SPI interface reduces pin counts and simplifies routing
  • Dual and quad I/O for increased read throughout
  • Ultra-fast 104 MHz operation
  • Uniform block erase architecture is ideal for embedded code and data storage
  • Comprehensive security and unique ID features protect the device from outside tampering
