1.Single Hi-Speed USB 2.0 chip (FT4222H) to flexible and configurable SPI/IC interfaces. SPI interface support for Single / Dual / Quad SPI Master Mode with configurable target operating speed. Up to 28Mbps data transfer rate in SPI mode with quad data mode. Support up to 4 slave selection control pins in SPI master mode. Support Single SPI Slave Mode with operating frequency up to 20MHz.2.IC interface support 7-bits address and fully compatible to v2.1 and v3 specification for I2C Master/Slave Mode with configurable target operating speed for 100kbit/S standard mode, 400kbit/S fast mode 1Mbit/S Fast mode plus and 3.4Mbit/S high speed mode. Configurable GPIOs controlled by application software via USB bus. Fully support USB2.0 suspend/resume and remote wakeup.3.Support Battery Charger Detection: OTP memory inside for USB Vendor ID (VID), Product ID (PID), device serial number, product description string and various other vendor specific data. USB Configurations; bus-powered and self-powered. On board jumper for FT4222H configuration mode, USB configuration and VCCIO source selection.4.Integrated -on-reset circuit. True 3.3V CMOS drive output and TTL input. (operates down to 1.8V with external 1.8V input to VCCIO) Support wide supply voltage range. USB2.0 Low operating and suspend current; 68mA (active-typ.) and 375uA (suspend-typ.).5.Configurable I/O pin output drive strength: 4mA (min) and 16mA (max) UHCI / OHCI / EHCI / XHCI host controller compatible. 's -free Direct (D2XX) drivers eliminate the requirement for USB driver development in most cases.Supplied PCB designed to fit a standard 20.2mm (0.8 inch) wide 24 pin DIP socket. Pins are on a 2.54mm (0.1inch) pitch.On board USB -B receptacle allows module to be connected to a PC.ApplicationsUSB to single mode SPI master controllerUSB to dual mode SPI master controllerUSB to quad mode SPI master controllerUSB to single SPI slave controllerUSB to IC master interface controllerUSB to IC slave interface controllerUtilizing USB to add system modularityIncorporate USB interface to enable PC transfers for development system communicationUSB Industrial ControlUSB Data AcquisitionAccessory connectivity solutions for mobiles and tabletsUSB dongle implementations for Software/Hardware Encryption and Wireless ModulesDetect USB dedicated charging ports, to allow for high current battery charging in portable devicesDriver Support free D2XX Direct Drivers (USB Drivers + S/W Interface)Windows 8.1: 32, 64-bitWindows 8: 32, 64-bitWindows 7: 32, 64-bitWin XP, Server 2003 and Server 2008size:6.6 x 2.9cmMaterial: PCBcolour: greenPackage Contents:1 x download moduleOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
