General description
The SC16C752B is a dual Universal Asynchronous Receiver/Transmitter (UART) with
64-byte FIFOs, automatic hardware/software flow control, and data rates up to 5 Mbit/s
(3.3 V and 5 V). The SC16C752B 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 TXRDYn/RXRDYn 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 on-board diagnostics.
The UART transmits data, sent to it over the peripheral 8-bit bus, on the TXn signal and
receives characters on the RXn signal. Characters can be programmed to be 5 bits, 6 bits,
7 bits, 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 has software
flow control and hardware flow control capabilities.
The SC16C752B is available in plastic LQFP48 and HVQFN32 packages.
