FTDI Chip FT4232HA Automotive High-Speed USB to UART/MPSSE
FTDI Chip FT4232HA Automotive High-Speed USB to UART/MPSSE is a turnkey solution for adding High-Speed USB support to a target design. The FT4232HA has four independent configurable interfaces. Two of these interfaces can be configured as UART, JTAG, SPI, I2C, or Bit-Bang mode, using an MPSSE with independent baud rate generators. The remaining two interfaces can be configured as UART or Bit-Bang. The FT4232HA is AEC Grade 2 qualified with an extended -40°C to +105°C operating temperature range.
The FTDI Chip FT4232HA Automotive High-Speed USB to UART/MPSSE is housed in a compact QFN-64 package and is Pb-free and RoHS compliant.
Features
