SC68C752B  
5 V, 3.3 V and 2.5 V dual UART, 5 Mbit/s (max.), with 64-byte  
FIFOs and 68 mode μP interface  
Rev. 04 — 20 January 2010  
Product data sheet  
1. 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.  
2. Features  
„ Dual channel with 68 mode (Motorola) μP interface  
„ Up to 5 Mbit/s data rate  
„ 64-byte transmit FIFO  
„ 64-byte receive FIFO with error flags  
„ Programmable and selectable transmit and receive FIFO trigger levels for DMA and  
interrupt generation  
„ Software/hardware flow control  
‹ Programmable Xon/Xoff characters  
‹ Programmable auto-RTS and auto-CTS  
„ Optional data flow resume by Xon any character  
„ DMA signalling capability for both received and transmitted data  
„ Supports 5 V, 3.3 V and 2.5 V operation
