Dual UART with dual infrared

The TL16PIR552 dual-channel UART gives designers control of a three-port system with a single device.

The IrDA interface offers a simple, inexpensive way to cordlessly connect PCs, notebooks, peripherals and other electronic equipments.

Unlike most IrDA devices, the TL16PIR552 allows the user to select between RS-232 and infrared I/O for the two serial ports. The device also has a 1284 parallel port supporting the ECP and EPP protocols, as well as standard Centronics mode.

Other features include 16-byte FIFOs to reduce interrupts, auto flow control to relieve the CPU from monitoring status flow information, and data transmission rates up to 1 Mbps.
