FT221X USB 8-BIT SPI/FT1248 IC Datasheet Version 1.4 Document No.: FT 000630 Clearance No.: FTDI 263 Future Technology Devices International Ltd. FT221X (USB 8-Bit SPI/FT1248 IC) USB Battery Charger Detection. Allows for USB The FT221X is a USB to FTDIs peripheral devices to detect the presence of a proprietary FT1248 interface with the higher power source to enable improved following advanced features: charging. Single chip USB to 1, 2, 4, or 8 bit wide Device supplied pre-programmed with unique synchronous interface. USB serial number. Similar to an SPI Slave with variable bus width. USB Power Configurations supports bus- powered, self-powered and bus-powered with Entire USB protocol handled on the chip. No power switching. 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 True 3.3V CMOS drive output and TTL input descriptors and CBUS I/O configuration. operates down to 1V8 with external pull-ups. Tolerant of 5V inputs. Fully integrated clock generation with no external crystal required plus optional clock Configurable I/O pin output drive strength 4 output selection enabling a glue-less interface mA(min) and 16 mA(max) to external MCU or FPGA. Integrated power-on-reset circuit. Data transfer rates to 1MByte/s. Fully integrated AVCC supply filtering - no 512 byte receive buffer and 512 byte transmit external filtering required. buffer utilising buffer smoothing technology to + 5V Single Supply Operation. allow for high data throughput. Internal 3V3/1V8 LDO regulators FTDIs royalty-free Virtual Com Port (VCP) and Direct (D2XX) drivers eliminate the Low operating and USB suspend current 8mA requirement for USB driver development in (active-typ) and 125uA (suspend-typ). most cases. Low USB bandwidth consumption. Configurable CBUS I/O pin. UHCI/OHCI/EHCI host controller compatible. USB 2.0 Full Speed capable. Extended operating temperature range -40 to 85 C. Available in compact Pb-free 20 Pin SSOP and QFN packages (both RoHS compliant).
