ZiLOG Sets the standards for SCCs

For over 20 years ZiLOG has set the standard for

Serial Communication Controllers. Based on the

industry acclaimed SCC core, ZiLOG offers a wide

variety of Serial Communication Controllers to meet

your application requirements.

Reduces the need for external logic

ZiLOG SCCs offer low power consumption, higher

performance, and superior noise immunity. The many

on-chip features offered in ZiLOG SCCs help dramatically

to reduce the need for external logic and code develop-

ment found in most of the competition.

8-bit Solutions

The standard serial and integrated communications

controller, Z85C30, allows you to easily implement a fully

integrated solution for many networking applications.

The enhanced dual and mono SCCs, the Z80230, Z85230

and the Z85233, include many features that make pro-

gramming easy. These parts also reduce CPU overhead,

allowing the programmer to select packet handling

response and improve cycle access recovery time.
