Bridgetek/FTDI's FT93x series embedded MCUs high performance 32-bit processor with 128kb flash memory

The Bridgetek FT93x series by Bridgetek/FTDI is a compact SuperBridge mcu that provides flexible bridging solutions between different technologies, including USB, UART, SPI and SD host.

The unique feature of the USB device port for the MCU is that in addition to supporting all standard classes, the device can simply switch to hard-coded D2xx mode, eliminating the need for a lot of complex USB encoding due to the built-in D2xx hardware engine. Since this is a smart bridge, the USB can then be paired with a wider range of interfaces than the standard USB bridge ASIC. The device is well suited as a bridge between USB and qspi, as well as an interface for the EVE series of graphics controllers, allowing it to support up to four small USB displays
