FT120T-R集成电路（IC）的控制器规格书PDF中文资料

The FT120 is a USB controller developed independently with close consideration of the industry classic, D12 chip. It communicates with a microcontroller over the generic parallel interface. The FT120 has the following advanced features:

• USB 2.0 Full Speed compatible.

• High performance USB device controller with integrated SIE, endpoint buffer, transceiver and voltage regulators.

• Supports 8-bit parallel interface to external microcontroller.

• Supports DMA operation

• Integrated 320 bytes of configurable endpoint buffer

• Ping-pong buffer scheme for primary endpoint increases data transfer throughput

• Multiple interrupt modes to facilitate both bulk and isochronous transfers.

• Dedicated clock output pin with programmable clock frequency (4 – 24 MHz)

• 30 kHz output clock provided during suspend.

• Integrated D+ pull-up resistor for USB connection

• USB connection indicator that toggles with USB transmit and receive activities.

• Supports bus-powered or self-powered applications.

• Single power supply operation at 3.3V or 5V.

• Internal 1.8V and 3.3V LDO regulators

• Integrated power-on-reset circuit.

• UHCI/OHCI/EHCI host controller compatible.

• -40°C to 85°C extended operating temperature range.

• Available in Pb-free TSSOP-28 and QFN-28 packages (RoHS compliant).

Typical Applications

• Provide USB port to Microcontrollers
