82C52  
CMOS Serial Controller Interface  
March 1997  
Features  
Description  
• Single Chip UART/BRG  
The Intersil 82C52 is a high performance programmable  
Universal Asynchronous Receiver/Transmitter (UART) and  
Baud Rate Generator (BRG) on a single chip. Utilizing the  
Intersil advanced Scaled SAJI IV CMOS process, the 82C52  
will support data rates up to 1M baud asynchronously with a  
16X clock (16MHz clock frequency).  
• DC to 16MHz (1M Baud) Operation  
• Crystal or External Clock Input  
• On-Chip Baud Rate Generator - 72 Selectable Baud  
Rates  
The on-chip Baud Rate Generator can be programmed for  
any one of 72 different baud rates using a single industry  
standard crystal or external frequency source. A unique pre-  
scale divide circuit has been designed to provide standard  
RS-232-C baud rates when using any one of three industry  
standard crystals (1.8432MHz, 2.4576MHz, or 3.072MHz).  
• Interrupt Mode with Mask Capability  
• Microprocessor Bus Oriented Interface  
• 80C86 Compatible  
• Single +5V Power Supply  
• Low Power Operation . . . . . . . . . . . . . . . 1mA/MHz Typ  
• Modem Interface  
A programmable buffered clock output (CO) is available and  
can be programmed to provide either a buffered oscillator or  
16X baud rate clock for general purpose system usage.  
• Line Break Generation and Detection  
• Operating Temperature Range:
