SCC
ZiLOG’s Family of
Serial Communication Controllers
8-bit Features include:
• Dual full-duplex channels (Z80230/Z85C30/Z85230)
• Single full-duplex channel (Z85233)
• Ability to accommodate a crystal oscillator, baud
rate generator, and digital phase-locked loop on
each channel
• Processing speeds up to 5Mbps
• Multi-protocol format (async, monosync, bisync,
SDLC/HDLC, SDLC/HDLC loop)
ZiLOG Sets the standards for SCCs
• Encodes in the follow modes: NRZI, FM0, FM1
and Manchester
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.
• CRC-16 or CRC-CCITT error detection
• 4-byte Transmit FIFO/8-byte Receive FIFO
(Z80230/Z85230/Z85233)
• 1-byte transmit FIFO/3-byte receive FIFO (Z85C30)
Reduces the need for external logic
16-bit Solutions
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.
The standard and integrated universal serial controllers,
Z16C30 and the Z16C32 offer 16-bit performance, with
processing speeds up to 20 Mbps.
16-bit Features include:
8-bit Solutions
• Single (Z16C32) and dual (Z16C30)
full-duplex channels
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.
• Accommodates two baud rate generators
and one digital phase-locked loop
• Processing speeds up to 10Mbps (Z16C30)
and 20Mbps (Z16C32)
• Multi-protocol format (async, monosync,
slaved monosync, bisync, isochronous,
nine-bit, SDLC/HDLC, SDLC/HDLC loop)
(additional 16-bit features on back)
