The XR16V27511 (V2751) is a high performance dual universal asynchronous receiver and transmitter (UART) with 64 byte TX and RX FIFOs. The device operates from 2.25 to 3.6 volts with 5 Volt tolerant inputs and is pin-to-pin and software compatible to Exar’s XR16L2751. The device includes 2 additional capabilities over the XR16V2750: Intel and Motorola data bus selection and a “PowerSave” mode to further reduce sleep current to a minimum during sleep mode.| Part No. | XR16V2751 |
