SC16C750B

SC16C750B 5 V, 3.3 V and 2.5 V UART with 64-byte FIFOs Rev. 05 — 17 October 2008 Product data sheet 1. General description The SC16C750B is a Universal Asynchronous Receiver and Transmitter (UART) used for serial data communications. Its principal function is to convert parallel data into serial data, and vice versa. The UART can handle serial data rates up to 3 Mbit/s. The SC16C750B is pin compatible with the TL16C750 and it will power-up to be functionally equivalent to the 16C450. Programming of control registers enables the added features of the SC16C750B. Some of these added features are the 64-byte receive and transmit FIFOs, automatic hardware flow control. The selectable auto-flow control feature significantly reduces software overload and increases system efficiency while in FIFO mode by automatically controlling serial data flow using RTS output and CTS input signals. The SC16C750B also provides DMA mode data transfers through FIFO trigger levels and the TXRDY and ...
