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).
