FT120

(USB Device Controller with

Parallel Bus IC)

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).
