 FT121 - USB full-speed device controller
The FT121 provides a cost and feature optimized USB full-speed device controller. The device provides an SPI slave interface to the host processor and has internal clocking allowing for space optimised designs. Offering USB connectivity with bulk, isochronous or interrupt endpoints, the device also includes USB Battery charger detection for recharging battery operated devices over USB.
 Key Hardware Features
  • USB 2.0 Full Speed compatible
  • SPI slave interface to host processor
  • Support for multiple interrupt modes to facilitate bulk and isochronous transfers
  • Fully autonomous DMA engines for fast data transfer
  • Integrated 2 kbytes of configurable endpoint buffer
  • Double buffer scheme for main endpoint improves data transfer rates.
  • Good USB connection indicator that blinks with USB transmit and receive activities.
  • Single power supply operation at 3.3V or 5V.
  • Internal 1.8V and 3.3V LDO regulators
  • Extended operating temperature range : -40°C to 85°C.
  • Available in Pb-free TSSOP-16 and QFN-16 packages (RoHS compliant).
