CMOS Serial Controller Interface
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).
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.

*Add "96" suffix for tape and reel.
**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.
