82C50A  
CMOS Asynchronous  
Communications Element  
March 1997  
Features  
Description  
• Single Chip UART/BRG  
The 82C50A Asynchronous Communication Element (ACE)  
is a high performance programmable Universal Asynchro-  
nous Receiver/Transmitter (UART) and Baud Rate Genera-  
tor (BRG) on a single chip. Using Intersil’s advanced Scaled  
SAJI IV CMOS Process, the ACE will support data rates  
from DC to 625K baud (0-10MHz clock).  
• DC to 625K Baud (DC to 10MHz Clock)  
• Crystal or External Clock Input  
• On Chip Baud Rate Generator 1 to 65535 Divisor  
Generates 16X Clock  
• Prioritized Interrupt Mode  
• Fully TTL/CMOS Compatible  
• Microprocessor Bus Oriented Interface  
• 80C86/80C88 Compatible  
• Scaled SAJI IV CMOS Process  
• Low Power - 1mA/MHz Typical  
• Modem Interface  
• Line Break Generation and Detection  
• Loopback and Echo Modes  
• Doubled Buffered Transmitter and Receiver  
• Single 5V Supply  
The ACE’s receiver circuitry converts start, data, stop, and  
parity bits into a parallel data word. The transmitter circuitry  
converts a parallel data word into serial form and appends  
the start, parity, and stop bits. The word length is program-  
mable to 5, 6, 7, or 8 data bits. Stop bit selection provides a  
choice of 1,1.5, or 2 stop bits.  
The Baud Rate Generator divides the clock by a divisor  
16  
programmable from 1 to 2 -1 to provide standard RS-232C  
baud rates when using any one of three industry standard  
baud rate crystals (1.8432MHz, 2.4576MHz, or 3.072MHz).  
A programmable buffered clock output (BAUDOUT) provides  
either a buffered oscillator or 16X (16 times the data rate)  
baud rate clock for general purpose system use.

To meet the system requirements of a CPU interfacing to an  
asynchronous channel, the modem control signals RTS,  
CTS, DSR, DTR, RI, DCD are provided. Inputs and outputs  
have been designed with full TTL/CMOS compatibility in  
order to facilitate mixed TTL/NMOS/CMOS system design.
