Renesas / Dialog DataFlash™ SPI Memory

Renesas / Dialog DataFlash™ SPI Memory devices are feature-rich, page-erase (as small as 256 bytes) SPI-compatible Serial Flash with advanced protection and security features. These 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. The DataFlash SPI Memory 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.


  • 1-Mbit to 64-Mbit densities
  • Small page array architecture
  • Individually erasable pages of 256/264, 512/528, or 1024/1056 bytes each
  • Byte-write provides Serial EEPROM functionality in a Serial NOR Flash device
  • SRAM buffer size equal to the memory page size
  • Software reset capability
  • Wide Vcc
  • Dual SRAM buffers
  • Command-rich instruction set
  • Enhanced low-power read
  • Zero-power shutdown options
  • Low power operation extends system battery life
  • 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
