DataFlash SPI Memory

DataFlash™ SPI Memory

Most Efficient Flash Memory for Data Logging

DataFlash’s advanced dual SRAM buffer architecture makes it the most efficient memory for data logging. It also incorporates a suite of advanced features that save system power, reduce processor overhead, simplify software development, and provide comprehensive data security and integrity options.

  • Byte / Page Programming
  • Fast Page Erase
  • Low Power Modes
  • Power Fail Protection
  • Data Integrity & Security

Key Features

  • Wide Vcc
  • Dual SRAM buffer
  • Low power operation extends system battery life
  • Byte-write provides Serial EEPROM functionality in a Serial NOR Flash device
,
  • 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
