Product Overview

The FT122Q-R is an enhanced USB Device Controller IC with parallel bus, provides a cost and feature optimized USB full-speed device controller. The design builds on the USB device controller IC, by adding battery charger detection and internal clocking to reduce the PCB space required to complete the design. Communicating with a microcontroller over the generic parallel interface the device will appear as another memory device on the processor bus, offering USB connectivity with bulk, isochronous or interrupt endpoints.
  • USB 2.0 full-speed compatible
  • Support for multiple interrupt modes to facilitate bulk and isochronous transfers
  • Fully autonomous DMA engines for fast data transfer
  • Supports high-speed parallel interface to external microcontroller
  • Separate address/data or multiplexed address/data bus
  • Integrated 2kb configurable endpoint buffer
  • Double buffer scheme for main endpoint improves data transfer rates
  • Dedicated clock output pin with programmable clock frequency (4 to 48MHz)
  • Good USB connection indicator that blinks with USB transmit and receive activities
  • Internal clocking (no external crystal required)
  • Battery charger detection
  • Single power supply operation at 3.3 or 5V
  • Internal 1.8 and 3.3V LDO regulators
  • Extended operating temperature range

Applications

Computers & Computer Peripherals, Industrial, Automation & Process Control
