Description

The TL16C2752 is a speed and functional upgrade of the TL16C2552. Since they are pinout and software compatible, designs can easily migrate from the TL16C2552 to the TL16C2752 if needed. The additional functionality within the TL16C2752 is accessed via an extended register set. Some of the key new features are larger receive and transmit FIFOs, embedded IrDA encoders and decoders, RS-485 transceiver controls, software flow control (Xon/Xoff) modes, programmable transmit FIFO thresholds, extended receive and transmit threshold levels for interrupts, and extended receive threshold levels for flow control halt/resume operation.

The TL16C2752 is a dual universal asynchronous receiver and transmitter (UART). It incorporates the functionality of two independent UARTs: each UART having its own register set and transmit and receive FIFOs.
