![]() ![]() Automatic half-duplex direction control and optional multi drop (9-bit) mode simplify both hardware and software in half-duplex RS-485 applications. Large 512-byte TX and RX FIFOs prevent buffer overflow errors and optimize data throughput. The UART pins for each port may also be configured as GPIO direction, state, output driver type and input pull-up or pull-down resistors are programmed either through on chip OTP, or on the fly via memory mapped registers. Any UART baud rate up to 12 Mbps may be generated with this internal clock and the fractional baud rate generator. The XR21B1424 includes an internal oscillator and does not require an external crystal/oscillator. The USB Vendor ID, Product ID, power mode, remote wakeup support, maximum power, and numerous other settings may be programmed in the on-chip OTP memory via the USB interface. The USB interface also supports USB suspend, resume and remote wakeup operations. The USB interface is fully compliant to the USB 2.0 (Full-Speed) specification with 12 Mbps USB data transfer rate. The XR21B1424 is an enhanced Universal Asynchronous Receiver and Transmitter (UART) bridge to USB interface. ![]()
