TL16C752BLPTREP

具有 64 字节 Fifo 的增强型产品 3.3V 双 Uart 48-LQFP -55 to 110

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.
