FT240X
(USB 8-BIT FIFO IC)
The FT240X is interface with
a USB to parallel FIFO the following advanced
features:
Single chip USB to parallel FIFO bidirectional data transfer interface.
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 FIFO I/O configuration.
Fully integrated clock generation with no external crystal required plus optional clock
output selection enabling glue-less interface to
external MCU or FPGA.
Data transfer rates up to 1Mbyte / second.
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 FIFO interface I/O pins.
Synchronous and asynchronous bit bang interface options.
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, selfpowered 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.
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 (activetyp) and 125uA (suspend-typ).
UHCI/OHCI/EHCI host controller compatible.
USB 2.0 Full Speed capable.
Extended operating temperature range; -40 to 85⁰C.
Available in compact Pb-free 24 Pin SSOP and QFN-24 packages (both RoHS compliant).
