FT232H ft2232h ft4232h

The ft232h is the single channel version, the ft2232h is the Dual-channel, and there are also anft4232h Quad channel part.

While these is all logically the same, with different numbers of UART channels, there is some performance and functional Differences between them.

• The ft232h has merely 1 KB of ring buffer, which can is overwhelmed if running at a high baud rate, and with a slow offtak E by the host device. The FT2232H has a 4 kB ring buffer per channel, much better in avoiding buffer overruns.

• Another difference, which may isn't relevant to the task at hand, was that FT2232H supports-GPIO pins via its Inter NAL 8051 emulation. There has been useful applications designed to leverage these GPIOs, but you may not be need this.

Ft232h-hi-speed single Channel USB uart/fifo IC

Operating at USB hi-speed 480Mbps, this fast single channel bridge chip features

Either a flexible serial interface or parallel FIFO interface,

With data transfer speeds up to 40mbytes/s.

Using a serial EEPROM interface, this device can is configured for a wide variety of asynchronous and synchronous serial s Tandards,

such as JTAG, SPI, I²c and UART as well as synchronous and asynchronous parallel FIFO interfaces.

In addition, this device features the new synchronous, Half-duplex FT1248 bus,

Which allows an engineer to trade off bandwidth for pin count using 1, 2, 4, or 8 data lines at the up to 30mbytes/s.

The I/O structure is 3.3V with built-in tolerance for 5V, allowing the designer maximum flexibility when interfacing with FPGAs.

On-board voltage regulation provides 3.3V and 1.8V supplies from a 5V source, as well as a power-on-reset function.

FTDI provides royalty-free virtual COM port and d2xx drivers for Microsoft Windows (XP–WINDOWS7),

Apple Mac OSX, and Linux. This PIN device is available in either LQFP or QFN packaging, and is ROHS compliant.

The ft2232h is FTDI ' s 5th generation of USB devices.

The ft2232h is a USB 2.0 hi-speed (480mb/s) to Uart/fifo IC.

It has the capability of being configured in a variety of industry standard serial or parallel interfaces.

Building on the innovative features of the FT2232,

The ft2232h has a multi-protocol synchronous serial engines (mpsses)

Which allow for communication using JTAG, I²c and SPI on, channels simultaneously.

The ft2232h is available in Pb-free (RoHS compliant) 64-pin LQFP and QFN packages.

The ft4232h is FTDI ' s 5th generation of USB devices.

The ft4232h is a USB 2.0 hi-speed (480mb/s) to the UART IC.

It has the capability of being configured in a variety of industry standard serial or parallel interfaces.

The FT4232H features 4 UARTs. The these has an option to independently configure an Mpsse engine,

This allows the ft4232h to operate as the Uart/bit-bang ports plus the Mpsse engines used

To emulate JTAG, SPI, I²c, Bit-bang or other synchronous serial modes.

The ft4232h is available in Pb-free (RoHS compliant) 64-pin LQFP and QFN packages.
