82C52
CMOS Serial Controller Interface
FN2950
Rev 4.00
November 25, 2015
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 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).
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
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.

**Pb-free PDIPs can be used for through hole wave solder processing only. They are not intended for use in Reflow solder processing applications.
NOTE: Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
termination finish, which are RoHS compliant and compatible with both SnPb and Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
