XR17D154CV Description

The XR17D154CV is a high-performance UART (Universal Asynchronous Receiver/Transmitter) interface IC chip designed by MaxLinear, Inc. This quad-channel device is engineered to provide reliable and efficient data communication over RS485 protocols. It supports a maximum data rate of 6.25 Mbps, making it suitable for applications requiring high-speed data transmission. The XR17D154CV is equipped with 64-byte FIFOs (First In, First Out) for each channel, which significantly enhances data buffering capabilities and reduces the risk of data loss during transmission. Additionally, it features false start bit detection, ensuring robust error handling and data integrity. The device operates on a supply voltage of either 3.3V or 5V, offering flexibility in power requirements. It also includes an IrDA encoder/decoder, expanding its communication capabilities. The XR17D154CV is packaged in a 144LQFP format and is suitable for surface mount applications. However, it is important to note that this product is now obsolete, and its production has been discontinued.
