Description
The SC16C754 is a quad universal asynchronous receiver/transmitter (UART) with
64-byte FIFOs, automatic hardware/software flow control, and data rates up to
5 Mbits/s (3.3 V and 5 V). The SC16C754 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. 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 loop-back capability allows on-board diagnostics.
The UART transmits data, sent to it over 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 has software flow control and hardware flow control
capabilities.
The SC16C754 is available in plastic LQFP80 and PLCC68 packages.
