Product Overview

The XR16M654IV64-F is an enhanced quad Universal Asynchronous Receiver and Transmitter (UART) each with 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 16Mbps at 4X sampling rate. Each UART has a set of registers that provide the user with operating status and control, receiver error indications and modem serial interface controls. An internal loopback capability allows onboard diagnostics. The XR16M654IV (64-pin) offers three state interrupt output. The rich feature set of the M654 is available through the internal registers. Automatic hardware/software flow control, selectable transmit and receive FIFO trigger levels, selectable baud rates, infrared encoder/decoder interface, 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.
