TL16C752BTPTREP

3.3 V双64字节FIFO的UART 3.3-V DUAL UART WITH 64-BYTE FIFO

description

The TL16C752B-EP is a dual-universal asynchronous receiver/transmitter UART with 64-byte FIFOs,

automatic hardware/software flow control, and data rates up to 3 Mbps. The TL16C752B-EP offers enhanced features. It has a transmission control register TCR that stores receiver FIFO threshold levels to start/stop transmission during hardware and software flow control. With the FIFO RDY register, the software gets the status of TXRDY/RXRDY for all four ports in one access.
