XR16V2652

The XR16V2652¹ (V2652) is a high performance dual universal asynchronous receiver and transmitter (UART) with 32 byte TX and RX FIFOs. The XR16V2652 operates from 2.25 to 3.6 volts with 5 Volt tolerant inputs and is pin-to-pin compatible to Exar's ST16C2552, XR16L2552, XR16V2552 and XR16L2752. The V2652 register set is compatible to the ST16C2552 and the XR16V2552. It supports the Exar's enhanced features of selectable FIFO trigger level, automatic hardware (RTS/CTS) and software 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. Independent programmable baud rate generators are provided in each channel to select data rates up to 16 Mbps at 3.3 Volt with 4X sampling clock. The XR16V2652 is available in 44-pin PLCC and 32-pin QFN packages.
