SCC68692C1A44,512

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The SCC68692C1A44,512 is a dual asynchronous receiver/transmitter (DUART) manufactured by NXP Semiconductors. It provides two full-duplex asynchronous channels within a single PLCC-44 package. The device operates on a single +5 V power supply with a minimum voltage of 4.5 V and a maximum of 5.5 V. It supports data transfer rates up to 1 MB/sec at 1X clock or 125 kB/sec at 16X clock. The operating current is 10 mA. The component is designed for commercial use within an ambient temperature range of 0°C to +70°C.
