SPI Flash Memory

• Memory
  • 32Megabits = 4Megabyte (MB)
• Voltage
  • 2.7V to 3.6V

This is origional GigaDevice GD25Q32 4MB SPI Memory chip.

Can be used in thousands of supported devices. for example routers, dish receivers, set top boxes, CPEs, lcds, laptops etc

• Memory
  • 64Megabits = 8Megabyte (MB)
• Voltage
  • 2.7V to 3.6V
• Family of SpiFlash Memories
  • GD25Q64: 64M-bit / 8M-byte
