Description

The ST16C554DIQ64-F is a model of quad Universal Asynchronous Receiver and Transmitter (UART) with 16 bytes of transmit and receive FIFOs, selectable receive FIFO trigger levels and data rates of up to 1.5 Mbps. The ST16C554/554D (554) is a pin-to-pin compatible device with the industry standard ST16C454, ST68C454, ST68C554, TI’s TL16C554A and Philips’ SC16C554B. It is designed with four independent UART channels, and each UART has a set of registers that provide the user with operating status and control, receiver error indications, and modem serial interface controls. The model operates on a range from 2.97V to 5.5V and has a crystal oscillator or external clock input.

The device is suitable for various applications such as portable appliances, telecommunication network routers, Ethernet network routers, cellular data devices, factory automation and process controls.
