Universal asynchronous receiver/transmitterThe TL16C754 is a four-channel universal asynchronous receiver/transmitter UART) that provides serial-to-parallel data conversion from peripherals or modems and parallel-to-serial data conversion on data transmitted by the host. Applications include PCs, fax/modems, telecom equipment or any application requiring an enhanced serial port. The new device, which is pin-compatible with the 16-byte TL16C554 quad UART, can be placed in an alternate (FIFO mode), relieving the processor of excessive software overhead by buffering received or transmitted characters. In addition, both the receiver and transmitter FIFOs can store up to 64 bytes, including three additional bits of error status per byte for the receiver FIFO. Primary outputs also allow for signaling of direct memory access (DMA) transfers. The device provides quad-channel integration for reduced board space and cost. The complete status of each channel can be read at any time during functional operation by the processor. It also supports high data throughput of up to 3.2 Mbps (60-MHz input clock) and contains a software interface for modem control operations. The TL16C754 is available in 80-pin TQFP and 68-pin PLCC packages. n For complete information, order: Data Sheet (SLLS279). See Related Product Information.
