The new-generation OctaFlash is built on Serial Peripheral Interface (SPI) and command set, providing extendable I/O capability. Expanding from current Quad I/O to OctaFlash Memory (8 I/O) will efficiently broaden our Serial NOR Flash throughput. Macronix OctaFlash Memory(8 I/O) also retains the user interface compatible with the ordinary Single I/O Serial NOR Flash, which can sustain users’ experience in using Serial NOR Flash with minimum efforts.

New OctaFlash NOR Memory devices also dedicate to raising the product performance with the fastest 200MHz frequency, combining with the brand-new Data Transfer Rate (DTR) feature. The data transfer rate has therefore been increased from existing 100MB/s of Quad I/O Serial NOR Flash to 400MB/s, while the read latency has also been lowered immensely. The improved performance will help OctaFlash in running eXecute In Place (XIP) with more efficiency and shorten the access time in high density, which accelerates overall system performance.

The new generation OctaFlash Memory offers both 1.8V and 3V power supply solutions, with densities from 128Mb to 2Gb.


Key Features

  • Backward compatible with x1 I/O SPI interface
  • Both STR & DTR (Double Transfer Rate) mode support
  • New DTR feature for Read, Program and Erase operation
  • Up to 200MHz clock frequency with both DTR/ STR operation
  • Fast read throughput of up to 400MB/s with DTR operation
  • Adjustable Dummy Cycles
  • Configuration Register
  • Individual Sector Protection


OctaFlash is the ideal solution for eXecute In Place (XIP), and a variety of high performance applications:

  • Automotive Cluster
  • Car Infotainment
  • Data Communication Module (Telematics, Emergency)
  • Digital Camera
