6 / 56 page  XR16M580 6 1.62V TO 3.63V HIGH PERFORMANCE UART WITH 16-BYTE FIFO REV. 1.0.0 Pin type: I=Input, O=Output, I/O= Input/output, OD=Output Open Drain. 1.0 PRODUCT DESCRIPTION The XR16M580 (M580) is a high performance single channel UART. The configuration registers set is 16550 UART compatible for control, status and data transfer. Additionally, the M580 channel has 16 bytes of transmit and receive FIFOs, Automatic RTS/CTS Hardware Flow Control, Automatic Xon/Xoff and Special Character Software Flow Control, infrared encoder and decoder (IrDA ver 1.0 and 1.1), programmable fractional baud rate generator with a prescaler of divide by 1 or 4, and data rate up to 16 Mbps. The XR16M580 can operate from 1.62 to 3.63 volts. The M580 is fabricated with an advanced CMOS process. Data Rate The M580 is capable of operation up to 16 Mbps at 3.3V with 4X internal sampling clock rate. The device can operate at 3.3V with a 24 MHz crystal on pins XTAL1 and XTAL2, or external clock source of 32 MHz on XTAL1 pin. With a typical crystal of 14.7456 MHz and through a software option, the user can set the prescaler bit and sampling rate for data rates of up to 3.68 Mbps. Enhanced Features The rich feature set of the M580 is available through the internal registers. Automatic hardware/software flow control, selectable transmit and receive FIFO trigger levels, selectable baud rates, infrared encoder/decoder, modem interface controls, and a sleep mode are all standard features. MCR bit-5 provides a facility for turning off (Xon) software flow control with any incoming (RX) character. The M580 includes new features such as 9-bit (Multidrop) mode, auto RS-485 half-duplex direction control, different baud rate for TX and RX, fast IR mode and fractional baud rate generator.
