TL16C552AFNR Description

Short technical summary and product information.

The TL16C552AFNR is an enhanced dual-channel UART from Texas Instruments, designed for microcomputer and microprocessor-based systems. It provides two serial input/output interfaces, performing serial-to-parallel conversion for received data and parallel-to-serial conversion for transmitted data.

 

Key features include 16-byte FIFOs on each channel to minimize CPU overhead, a maximum clock rate of 16MHz supporting up to 1-Mbaud operation, and independent control for transmit, receive, line status, and data set interrupts. The device also includes individual modem control signals for each channel and programmable serial interface characteristics such as character length (5-8 bits), parity generation/detection, and stop bit generation.

 

This UART operates within a voltage range of 4.75V to 5.25V and has an operating temperature range of -40°C to 85°C. It is supplied in a 68-PLCC surface mount package. The TL16C552AFNR is hardware and software compatible with the TL16C452 and is an enhanced version of the TL16C550B ACE.
