REV. 1.0.1
1.62V TO 3.63V HIGH PERFORMANCE UART WITH 16-BYTE FIFO
1.0
PRODUCT DESCRIPTION
The XR16M570 (M570) is a higher performance single channel UART. The configuration registers set is
16550 UART compatible for control, status and data transfer. Additionally, the M570 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 XR16M570
can operate from 1.62 to 3.63 volts. The M570 is fabricated with an advanced CMOS process.
Data Rate
The M570 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 64 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 M570 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 M570 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.
