TL16C752CIPFBR
双UART，具有64字节FIFO DUAL UART WITH 64-BYTE FIFO
DESCRIPON
The TL16C752C is a quad universal asynchronous receiver/transmitter UART with 64-byte FIFOs, automatic hardware/software flow control, and data rates up to 3 Mbps. It incorporates the functionality of four UARTs, each UART having its own register set and FIFOs. The four UARTs share only the data bus interface and clock source, otherwise they operate independently.
