SC68C652B  
5 V, 3.3 V and 2.5 V dual UART, 5 Mbit/s (max.) with 32-byte  
FIFOs, IrDA encoder/decoder, and 68 mode µP interface  
Rev. 02 — 2 November 2009  
Product data sheet  
1. General description  
The SC68C652B is a 2 channel Universal Asynchronous Receiver and Transmitter  
(UART) used for serial data communications. Its principal function is to convert parallel  
data into serial data and vice versa. The UART can handle serial data rates up to 5 Mbit/s.  
The SC68C652B is pin compatible with the SC68C2550B. The SC68C652B provides  
enhanced UART functions with 32-byte FIFOs, modem control interface, DMA mode data  
transfer, and infrared (IrDA) encoder/decoder. The DMA mode data transfer is controlled  
by the FIFO trigger levels and the TXRDYn and RXRDYn signals. On-board status  
registers provide the user with error indications and operational status. System interrupts  
and modem control features may be tailored by software to meet specific user  
requirements. An internal loopback capability allows on-board diagnostics. Independent  
programmable baud rate generators are provided to select transmit and receive baud  
rates.  
The SC68C652B operates at 5 V, 3.3 V and 2.5 V and the industrial temperature range,  
and is available in the plastic LQFP48 package.  
2. Features  
I 2 channel UART with 68 mode (Motorola) µP interface  
I 5 V, 3.3 V and 2.5 V operation  
I 5 V tolerant on input only pins1  
I Industrial temperature range (−40 °C to +85 °C)  
I Software compatible with industry standard 16C450, 16C550, and SC16C650  
I Up to 5 Mbit/s baud rate at 5 V and 3.3 V, and 3 Mbit/s at 2.5 V  
I 32-byte transmit FIFO to reduce the bandwidth requirement of the external CPU  
I 32-byte receive FIFO with error flags to reduce the bandwidth requirement of the  
external CPU  
I Independent transmit and receive UART control  
I Four selectable receive and transmit FIFO interrupt trigger levels  
I Automatic software (Xon/Xoff) and hardware (RTSn/CTSn) flow control  
I Programmable Xon/Xoff characters  
I Software selectable baud rate generator  
I Standard modem interface or infrared IrDA encoder/decoder interface  
I Supports IrDA version 1.0 (up to 115.2 kbit/s)  
I Sleep mode
