概要
Description
TL16C752BTPTREP is a Texas Instruments dual UART (two independent 16550-compatible serial interfaces) in a Pb-free package with tape-and-reel packaging. Each channel provides a standard 16550-style register set, a programmable baud-rate generator, and a FIFO buffer (typically 16 bytes) to reduce CPU overhead. The device supports common modem-control lines, interrupt outputs per channel, and a familiar programming model for serial communication applications. It is designed to simplify adding two serial ports to microcontrollers or processors and to drop in for 16550/16550A-compatible designs.
Note: exact electrical specs (supply voltage, clock requirements, timing, and pinout) vary by package and revision. For precise details, consult the TL16C752 datasheet and the product documentation for the BTPTREP variant.
