FT220X - Single chip USB to 4-Bit SPI/FT1248 interface IC

This USB2.0 Full Speed  IC offers a compact bridge to 4-Bit SPI/FT1248 interfaces, with low power consumption (8mA), and  includes the complete FT-X series feature set enabling USB to be added into a system design quickly and easily over an FT1248 interface.

Key features:

  • FT1248 serial parallel interface in 1, 2 or 4 bit wide mode.
  • Entire USB protocol handled on the chip. No USB specific firmware programming required.
