XR16L570中文资料Smallest 1.62V to 5.5V UART with 16-Byte FIFO and Power-Save数据手册MaxLinear规格书

描述 Description

The XR16L570 (L570) is a 1.62 to 5.5 volt Universal Asynchronous Receiver and Transmitter (UART) with 5 volt tolerant inputs and a reduced pin count. It is software compatible to industry standard 16C450, 16C550, ST16C580, ST16C650A, XR16C850 and XR16L580 UARTs. It has 16 bytes of TX and RX FIFOs and is capable of operating with a serial data rate of up to 4 Mbps at 5V, 3 Mbps at 3.3V,1 Mbps at 2.5V and 750 Kbps at 1.8V. The internal registers are compatible to the 16C550 register set plus enhanced registers for additional features to support today’s high bandwidth data communication needs. The enhanced features include automatic hardware and software flow control to prevent data loss, selectable RX and TX trigger levels for more efficient interrupt service, wireless infrared (IrDA) encoder/decoder for wireless applications and a unique Power-Save mode to increase battery operating time. The device comes in 32-QFN and 24-QFN packages in industrial temperature range.
