FT240X USB 8-BIT FIFO IC Datasheet
Document No.: FT_000626 Clearance No.: FTDI# 259
Devices International Ltd.
(USB 8-BIT FIFO IC)
The FT240X is a USB to parallel FIFO
interface with the following advanced
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
Configurable FIFO interface I/O pins.
Synchronous and asynchronous bit bang
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
USB Power Configurations; supports bus- powered,
self-powered and bus-powered with power
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
+5V Single Supply Operation.
Internal 3V3/1V8 LDO regulators
