The XR16V554DIVTR-F from Exar Corporation is a member of the Exar Universal Asynchronous Receiver Transmitter (UART) family, specifically designed for high-speed transmission and system management. The device is available in a range of 10-pin through-hole packages, making it ideal for space-constrained applications. This UART chip is unique because of its onboard XR17V356 GreenFET3 integrated power management circuit, which combines the features of an embedded UART with low-power modes and analog-to-digital converter (ADC) features with a complete system power management solution.

The XR16V554DIVTR-F application is typically used in devices such as cellular/VoIP phones, PDAs, automotive systems, energy management systems, healthcare equipment, and industrial/consumer application systems. The device is capable of communication over a variety of interfaces, including Asynchronous Serial Interface (ASI) 4 and 6 (UART 4 and 6) ports. The device has an on-board serial bus formatter, allowing it to interface with other controllers and microcontrollers.

The XR16V554DIVTR-F UART operates on an Asynchronous Communications Interface (ACI) protocol and is capable of data rates up to 2.8Mb/s with a 3.3V power supply. The device is designed to provide higher data rates and reduce power consumption. It also offers flexible data framing options, which enable the use of parity checking, 7/8 bit data widths, and stop bit settings. This UART can be used in a variety of applications, including in high-speed communication systems, vehicle control systems, and energy management devices.

The XR16V554DIVTR-F UART includes several features that enable it to be used in a wide range of applications. It can be configured to operate at up to 5.16Mb/s. It features two separate data buses, one dedicated to transmitting data and the other dedicated to receiving data. The device has an internal FEC (forward error correction) engine, which can detect single and multiple errors occurring during transmission and correct the errors. It also supports hardware flow control, which enables users to ensure reliable communication between devices.

The XR16V554DIVTR-F UART device also includes an integrated DMA (direct memory access) controller. This DMA controller allows for direct communication between the device and its connected peripherals, such as cameras, displays, and storage devices. The integrated DMA controller helps reduce system latency by allowing for data to transfer directly from the UART device to the peripheral devices without involving the CPU. The device also supports an interrupt mechanism, allowing the processor to respond quickly when an event occurs.

Overall, the XR16V554DIVTR-F UART device is an ideal solution for embedded applications. Its combination of features and on-board power management make it an appealing choice for applications requiring reliable communication, high-speed data transmission, and low power consumption. Its on-board DMA controller and interrupt features make it suitable for many digital systems and its FEC engine helps to ensure reliable communication with connected variables.
