FT220X
(USB 4-BIT SPI/FT1248 IC)
USB Battery Charger Detection. Allows for USB
peripheral devices to detect the presence of a
higher power source to enable improved
charging.
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.
Device supplied pre-programmed with unique
USB serial number.
Similar to an SPI slave in 1 bit mode
USB Power Configurations; supports bus-
powered, self-powered and bus-powered with
power switching.
Entire USB protocol handled on the chip. No
USB specific firmware programming required.
Integrated +3.3V level converter for USB I/O.
Fully
integrated
2048
byte
multi-time-
programmable (MTP) memory, storing device
descriptors and CBUS I/O configuration.
True 3.3V CMOS drive output and TTL input.
(operates down to 1V8 with external pull-ups)
Tolerant of 5V input.
Fully integrated clock generation with no
external crystal required plus optional clock
output selection enabling a glue-less interface
to external MCU or FPGA.
Configurable I/O pin output drive strength; 4
mA(min) and 16 mA(max)
Integrated power-on-reset circuit.
Data transfer rates to 500kByte/s.
Fully integrated AVCC supply filtering - no
external filtering required.
512 byte receive buffer and 512 byte transmit
buffer utilising buffer smoothing technology to
allow for high data throughput.
+ 5V Single Supply Operation.
Internal 3V3/1V8 LDO regulators
FTDI’s royalty-free Virtual Com Port (VCP) and
Direct
requirement for USB driver development in
most cases.
