Data Flash 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 processtor overhead, simplify software development, and provide comprehensive data security and integrity options.
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
