Future Technology Devices

International Ltd

FT200XD

(USB I2C SLAVE IC)

The FT200XD is a USB to I

C interface

with the following advanced features:



Single chip USB to I

C interface.

Up to 3.4MHz, high speed mode, I C supported

Entire USB protocol handled on the chip. No

USB specific firmware programming required.

Fully

integrated

2048

byte

multi-time-

programmable (MTP) memory storing device

descriptors and CBUS I/O configuration.

Fully integrated clock generation with no

external crystal required plus optional clock

output selection enabling a glue-less interface

to external MCU or FPGA.

512 byte receive buffer and 512 byte transmit

buffer utilising buffer smoothing technology to

allow for high data throughput.

FTDI’s royalty-free Virtual Com Port (VCP) and

Direct

(D2XX)

drivers

eliminate

the

requirement for USB driver development in

most cases.

Unique USB FTDIChip-ID™ feature.

Configurable CBUS I/O pin.

Transmit and receive LED drive signals.

USB Battery Charger Detection. Allows for USB

peripheral devices to detect the presence of a

higher power source to enable improved

charging.

Device supplied pre-programmed with unique

USB serial number.



USB Power Configurations; supports bus-

powered, self-powered and bus-powered with

power switching.

Integrated +3.3V level converter for USB I/O.

True 3.3VCMOS drive output and TTL input;

Operates down to 1V8 with external pull-ups.

Tolerant of 5V input.

Configurable I/O pin output drive strength; 4

mA(min) and 16 mA(max).

Integrated power-on-reset circuit.

Fully integrated AVCC supply filtering - no

external filtering required.

+ 5V Single Supply Operation.

Internal 3V3/1V8 LDO regulators

Low operating and USB suspend current; 8mA

(active-typ) and 125uA (suspend-typ).

UHCI/OHCI/EHCI host controller compatible.

USB 2.0 Full Speed compatible.

Extended operating temperature range; -40⁰C

to +85⁰C.

Available in compact Pb-free 10 Pin DFN

package (3mmx3mm) (RoHS compliant).
