Quad UART with 64-byte FIFO and 3 Mbps link budget
The TL16CP754CIPM is a quad UART from Texas Instruments integrating four independent UART channels with 64-byte FIFOs per channel, supporting data rates up to 3 Mbps. The 64-byte FIFO depth allows the host processor to batch read/write operations, reducing interrupt overhead on a 3 Mbps serial link — each FIFO can buffer roughly 21 microseconds of data at full rate before service is required. The part includes an internal oscillator, modem control signals, auto flow control, IrDA encoder/decoder, and false start bit detection — features that simplify the BOM for RS-485 or RS-232 multi-port designs.
