Dual UART with 16-byte FIFOs – design fit
Each channel includes a 16-byte FIFO to buffer transmit and receive data, reducing CPU interrupt overhead in systems handling moderate serial traffic. The part supports a maximum data rate of 5 Mbps, making it suitable for high-speed industrial links, telecom line cards, or multi-port serial adapters. This simplifies power rail design in mixed-voltage systems common in factory automation and embedded control.
Integrated flow control and IrDA – what it saves you
Built-in modem control signals (RTS/CTS) and auto flow control hardware handle handshaking without firmware polling, freeing the host MCU for other tasks. The inclusion of an IrDA encoder/decoder allows direct connection to infrared transceivers for wireless serial links in handheld or panel-mount equipment.
No last-time-buy or obsolescence risk is indicated.
