82C52

CMOS Serial Controller Interface

DATASHEET

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.

**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.
