DESCRIPTION  
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. Another name for the UART function is asynchronous  
communications element (ACE), and these terms are used interchangeably. The bulk of this document describes  
the behavior of each ACE, with the understanding that four such devices are incorporated into the TL16C752C.  
The TL16C752C offers enhanced features. It has a transmission control register (TCR) that stores received FIFO  
threshold level 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. On-chip status registers provide  
the user with error indications, operational status, and modem interface control. System interrupts may be  
tailored to meet user requirements. An internal loopback capability allows onboard diagnostics.  
Each UART transmits data sent to it from the peripheral 8-bit bus on the TX signal and receives characters on  
the RX signal. Characters can be programmed to be 5, 6, 7, or 8 bits. The UART has a 64-byte receive FIFO and  
transmit FIFO and can be programmed to interrupt at different trigger levels. The UART generates its own  
desired baud rate based upon a programmable divisor and its input clock. It can transmit even, odd, or no parity  
and 1-, 1.5-, or 2-stop bits. The receiver can detect break, idle or framing errors, FIFO overflow, and parity errors.  
The transmitter can detect FIFO underflow. The UART also contains a software interface for modem control  
operations, and software flow control and hardware flow control capabilities.  
The TL16C752C is available in a 32-pin QFN (RHB) package. A 48-pin QFP (PFB) package will be available in  
late 2008.
