Description

  The SC16C654/654D is a 4-channel 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.TheUARTcanhandleserialdata rates up to 5 Mbits/s. It comes with an Intel or Motorola interface.

  The SC16C654/654D 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 SC16C654/654D. 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 significantlyreducessoftwareoverloadandincreasessystemefficiencywhileinFIFO mode by automatically controlling serial data flow using RTS output and CTS input signals. The SC16C654/654D also provides DMA mode data transfers through FIFO trigger levels and the TXRDY and RXRDY signals. 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 SC16C654/654Doperatesat5 V,3.3 Vand2.5 V,andtheindustrialtemperature range, and is available in plastic PLCC68 and LQFP64 packages.
