Key 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.
- Data transfer rates to 500 kByte/s
- 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.
- I/O levels from 1.8V to 3.3V. (5V tolerant inputs).
- 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.
- 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.
- 20 Pin SSOP and QFN packages (both RoHS compliant).
- FT1248 serial parallel interface in 1, 2, 4 or 8 bit wide
mode.
