SC16C654B/654DB Rev. 02 — 20 June 2005 www.DataSheet4U.com 5 V, 3.3 V and 2.5 V quad UART, 5 Mbit/s (max.), with 64-byte FIFOs and infrared (IrDA) encoder/decoder Product data sheet 1. General description The SC16C654B/654DB is a Quad Universal Asynchronous Receiver and Transmitter (QUART) 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 5 Mbit/s. It comes with an Intel or Motorola interface. The SC16C654B/654DB is pin compatible with the ST16C654 and TL16C754 and it will power-up to be functionally equivalent to the 16C454. Programming of control registers enables the added features of the SC16C654B/654DB. Some of these added features are the 64-byte receive and transmit FIFOs, automatic hardware or software flow control and infrared encoding/decoding. 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 SC16C654B/654DB also provides DMA mode data transfers through FIFO trigger levels and the TXRDY and RXRDY signals. (TXRDY and RXRDY signals are not available in the HVQFN48 package.) On-board status registers provide the user with error indications, operational status, and modem interface control. System interrupts may be tailored to meet user requirements. An internal loop-back capability allows on-board diagnostics. The SC16C654B/654DB operates at 5 V, 3.3 V and 2.5 V, and the industrial temperature range, and is available in plastic PLCC68, LQFP64, HVQFN48 and LFBGA64 packages. On the HVQFN48 package, only channel C has all the modem pins. Channel A and channel B have only RTS and CTS pins, and channel D does not have any modem pin. 2.
