P1.0.0 GENERAL DESCRIPTION The XR16M27521 (M2752) is a high performance dual universal asynchronous receiver and transmitter (UART) with 64 byte TX and RX FIFOs. The device operates from 1.62 to 3.6 volts and is pin-to-pin compatible to Exar’s ST16C2552, XR16L2552, XR16L2752 and XR16V2752. The M2752 register set is identical to the XR16V2752 and is compatible to the ST16C2552 and the XR16C2852 enhanced features. It supports the Exar’s enhanced features of programmable FIFO trigger level and FIFO level counters, automatic hardware (RTS/CTS) and software flow control, automatic RS-485 half duplex direction control output and a complete modem interface. Onboard registers provide the user with operational status and data error flags. An internal loopback capability allows system diagnostics. Independent programmable baud rate generators are provided in each channel to select data rates up to 8 Mbps at 3.3 Volt and 8X sampling clock. The M2752 is available in 44-pin PLCC and 32-pin QFN packages.
