Future Technology Devices International Ltd. FT220X
(USB 4-BIT FT1248 IC)
The FT220X is a USB to FTDI’s proprietary FT1248 interface and the following advanced
features:
FT1248 serial parallel interface in 1, 2 or 4 bit
wide mode.
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.
Data transfer rates to 500kByte/s.
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.
Configurable CBUS I/O pin.
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 buspowered, self-powered and bus-powered with power switching.
Integrated +3.3V level converter for USB I/O.
True 3.3V CMOS 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).
Low USB bandwidth consumption.
UHCI/OHCI/EHCI host controller compatible.
USB 2.0 Full Speed compatible.
Extended operating temperature range; -40 to 85⁰C.
Available in compact Pb-free 16 Pin SSOP and QFN packages (both RoHS compliant).
