FT221X – Full Speed USB to 8-Bit FT1248 Bridge

This USB2.0 Full Speed IC offers a compact bridge to 8-Bit FT1248 interfaces. The device is a FT1248 slave, capable of operating up to 1MByte/s, with low power consumption (8mA). The FT221X includes the complete FT-X series feature set and enables USB to be added into a system design quickly and easily over an FT1248 interface

Key Hardware Features

FT1248 serial parallel interface in 1, 2, 4, or 8 bit wide mode.
Similar to an SPI slave in 1 bit mode
Entire USB protocol handled on the chip. No USB specific firmware programming required.
Fully integrated 2048 byte MTP Memory for 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 1MByte/s.
512 byte receive buffer and 512 byte transmit buffer utilizing 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.
Device supplied pre-programmed with unique USB serial number.
Supports bus powered, self powered and high-power bus powered USB configurations.
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)
I/O levels from 1.8V to 3.3V. (5V tolerant inputs).
Configurable I/O pin output drive strength.
Battery Charger Detection. May be used by mobile devices to detect the presence of a charger on the USB port to enable higher current / faster charging of batteries.
Integrated power-on-reset circuit.
Internal 3.3V/1.8V LDO regulators
Low operating current of 8mA (typical) and USB suspend current of 125uA (typical) current.
Low USB bandwidth consumption.
UHCI/OHCI/EHCI host controller compatible.
USB 2.0 Full Speed compatible.
Extended operating temperature range: -40°C to 85°C
20 Pin SSOP and QFN packages (both RoHS compliant).
