Product data sheet
1. General description
The SC68C752B is a dual Universal Asynchronous Receiver/Transmitter (UART) with
64-byte FIFOs, automatic hardware/software 鏗俹w 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 鏗俹w 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 over鏗俹w, and parity errors. The transmitter can detect FIFO under鏗俹w. The UART
also contains a software interface for modem control operations, and has software 鏗俹w
control and hardware 鏗俹w control capabilities.
The SC68C752B is available in a plastic LQFP48 package.
