XR16M781 1.62V TO 3.63V UART WITH 64-BYTE FIFO AND VLIO INTERFACE AUGUST 2009 REV. 1.0.1 GENERAL DESCRIPTION The XR16M7811 (M781) is an enhanced Universal Asynchronous Receiver and Transmitter (UART) with a VLIO bus interface and has 64 bytes of transmit and receive FIFOs, programmable transmit and receive FIFO trigger levels, automatic hardware and software flow control, and data rates of up to 20 Mbps at 3.3V, 16 Mbps at 2.5V and 10 Mbps at 1.8V with 4X data sampling rate. The Auto RS-485 Half-Duplex Direction control feature simplifies both the hardware and software for half-duplex RS-485 applications. In addition, the Multidrop mode with Auto Addr

XR16M781 1.62V TO 3.63V UART WITH 64-BYTE FIFO AND VLIO INTERFACE Pin Description REV. 1.0.1 NAME CTS# DTR# DSR# CD# RI# 24-QFN PIN# 32-QFN PIN# 25-BGA PIN# TYPE DESCRIPTION 18 24 A1 I UART Clear-to-Send (active low) or general purpose input. It can be used for auto CTS flow control, see EFR[7], MSR[4] and IER[7]. This input should be connected to VCC when not used. - 22 B3 O UART Data-Terminal-Ready (active low) or general purpose output. - 25 C4 I UART Data-Set-Ready (active low) or general purpose input. This input should be connected to VCC when not used. - 26 - I UART Carrier-Detect (active low) or general purpose input. This input should be connected to VCC when not used. - 27 - I UART Ring-Indicator (active low) or general purpose input. This input should be connected to VCC when not used.

O Crystal or buffered clock output. I Power-Save (active high). This feature isolates the M781’s data bus interface from the host preventing other bus activities that cause higher power drain during sleep mode. See Sleep Mode with Auto Wake-up and Power-Save Feature section for details. This pin does not have an internal pull-down resistor. This input should be con- nected to GND when not used. O Device reset (active low). A 40 ns minimum LOW pulse on this pin will reset the internal registers and
