UART/MPSSE IC delivers high-speed USB support

This is an automotive-qualified USB 2.0-to-UART converter that seamlessly provides high-speed USB support to target designs.

Featuring four independent configurable interfaces, the device offers a highly flexible solution for a range of both automotive and general USB applications, including smart card readers, industrial control, media player interfaces, and set-top box interfaces.

It supports single-chip USB-to-quad serial ports with a variety of configurations.

Two of the device’s four configurable interfaces can be configured as UART, JTAG, SPI, I²C, or Bit-Bang mode, using an MPSSE with independent baud rate generators, while the remaining two interfaces can be configured as UART or Bit-Bang.

Suitable for a range of automotive applications, the highly durable FT4232HA device is AEC Grade 2 qualified with an extended operating temperature range of -40°C to +105°C. The IC also features low operating and USB suspend currents and supports bus-powered, self-powered, and high-power bus-powered USB configurations.

For development, Mouser also offers the FT4232HA Mini Module, a small evaluation board that features a pre-installed FT4232HA and an onboard USB port that allows easy connection to a PC. The evaluation module also includes two 26-pin dual-row headers to enable easy connection to PCB header sockets and ribbon cables.
