XR16M752

The XR16M752¹ (M752) is a high performance dual universal asynchronous receiver and transmitter (UART) with 64 byte TX and RX FIFOs. The M752 operates from 1.62 to 3.63 volts. It is pin-to-pin and software compatible to the TL16C752B and SC16C752B, but with additional features such as a programmable fractional baud rate generator, automatic RS-485 half-duplex direction control, infrared mode and 8X and 4X sampling rate. The standard features include 16 selectable TX and RX FIFO trigger levels, automatic hardware (RTS/CTS) and software (Xon/Xoff) flow control, and a complete modem interface. Onboard registers provide the user with operational status and data error flags. An internal loopback capability allows system diagnostics. Each channel of XR16M752 is independently programmable for data rates up to 16 Mbps at 3.3 Volt with a 4X sampling rate. The M752 is available in the 48-pin TQFP and 32-pin QFN packages.
