cjmcu-2232hl USB Diy Kit
- Module size: 42mm * 37mm Typical Applications Single chip USB to dual channel UART (RS232, RS422 or RS485). Single chip USB to dual channel FIFO. Single chip USB to dual channel JTAG.
- Single chip USB to dual channel SPI. Single chip USB to dual channel I2C.
- Single chip USB to dual channel Bit-Bang. Single chip USB to dual combination of any of above interfaces. Single chip USB to Fast Serial Optic Interface. Single chip USB to CPU target interface (as memory), double and independent.
- This allows the user to communicate with the USB interface via a standard PC serial emulation port (for example TTY).
- Another FTDI USB driver, the D2XX driver, can also be used with application software to directly access the FT2232H through a DLL.
Key Hardware Features
The cjmcu-2232hl 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 two multi-protocol synchronous serial engines (MPSSEs) which allow for communication using JTAG, I2C and SPI on two channels simultaneously.
The FT2232H is available in Pb-free (RoHS compliant) 64-pin LQFP/QFN and 56-pin QVFN packages.
Single chip USB to dual serial / parallel ports with a variety of configurations.
Entire USB protocol handled on the chip. No USB specific firmware programming required.
USB 2.0 High Speed (480Mbits/second) and Full Speed (12Mbits/second) compatible.
cjmcu-2232hl Dual Multi-Protocol Synchronous Serial Engine (MPSSE) to simplify synchronous serial protocol (USB to JTAG, I2C, SPI or bit-bang) design.
