Description

82C52 March 1997 CMOS Serial Controller Interface Description 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).
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 prescale 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).
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.
Features • Single Chip UART/BRG • DC to 16MHz (1M Baud) Operation • Crystal or External Clock Input • On-Chip Baud Rate Generator - 72 Selectable Baud Rates • Interrupt Mode with Mask Capability • Microprocessor Bus Oriented Interface • 80C86 Compatible • Single +5V Power Supply • Low Power Operation .
