ST16C2550CJ44-F

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The ST16C2550CJ44-F is a dual Universal Asynchronous Receiver/Transmitter (UART) interface integrated circuit manufactured by MaxLinear. It operates within a supply voltage range of 2.97 V to 5.5 V, supporting both 3.3 V and 5 V logic levels. The device features two independent UART channels, each equipped with 16-byte transmit and receive FIFOs to enhance data throughput and reduce processor overhead. It supports data rates up to 4 Mb/s and functions reliably in commercial temperature environments ranging from 0°C to +70°C. The component is housed in a 44-lead PLCC surface-mount package.
