TL16C550DIZQSR Description

Short technical summary and product information.

The TL16C550DIZQSR from Texas Instruments is an Asynchronous Communications Element (ACE) designed for serial communication.

 

This UART IC offers a single channel with programmable baud rate generation and supports various communication parameters including 5, 6, 7, or 8 data bits, even/odd/no parity, and 1, 1.5, or 2 stop bits. It features 16-byte transmit and receive FIFOs, which help reduce CPU overhead by buffering data.

 

Key electrical characteristics include support for 5-V, 3.3-V, and 2.5-V operation, with maximum clock rates up to 24 MHz at 5V (1.5 Mbaud) and up to 48 MHz at 3.3V (3 Mbaud) under specific conditions. The device includes programmable auto-RTS and auto-CTS for flow control, false start bit detection, and modem control functions.

 

The TL16C550DIZQSR is available in a 24-BGA MICROSTAR JUNIOR (3x3) package and is designed for surface mount installation. It is functionally equivalent to the TL16C450 but with enhanced FIFO buffering capabilities.
