TL16C550CIPTR

UARTs (Universal Asynchronous Receiver Transmitter) Overview

The TL16C550CIPTR is a single-channel asynchronous communications element (ACE) manufactured by Texas Instruments. It features 16-byte transmit and receive FIFOs with three additional error status bits per byte in the receiver buffer. The device supports data rates up to 1 Mbaud with a maximum clock rate of 16 MHz. It operates on supply voltages ranging from 3 V to 5.25 V, with typical operation at 3.3 V or 5 V. The unit draws approximately 10 mA during operation and functions within an industrial temperature range of -40°C to +85°C. It is housed in a 48-pin LQFP package.
