General description

The SC68C752B 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.

The SC68C752B 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 SC68C752B is available in LQFP48 and HVQFN32 packages.
