The ZiLOG Family of Serial
Communication Controllers
Setting the standards for SCCs
Over the last 20 years ZiLOG has set the standard for
SCCs. Built from the industry acclaimed Serial
Communication Controller core, ZiLOG offers a wide
selection of (SCCs) based on your application require-
ments.
®
Reducing the need for external logic
ZiLOG’s SCCs offer low power consumption, higher per-
formance, and superior noise immunity. The many
on-chip features offered in our SCCs help dramatically to
reduce the need for external logic found with much of the
competition. Go with an SCC you can trust, and make
ZiLOG your one-stop SCC solution provider.
• Ability to accommodate a crystal oscillator,
baud rate generator, and digital phase-locked
loop on each channel
• Processing speeds up to 5 Mbps
• Multi-protocol format (async, monosync,
bisync, SDLC/HDLC, SDLC/HDLC loop)
• Encodes in the following modes: NRZI, FM0,
FM1, and Manchester
• CRC-16 or CRC-CCITT error detection
• 4-byte transmit FIF0/8-byte receive FIF0
Offering a fully integrated solution
The standard serial and integrated communications con-
trollers, Z85C30 and Z16C35, allow you to easily imple-
ment a fully integrated solution for many networking
applications. The chips’ features include:
• Dual full-duplex channels
• Ability to accommodate a crystal oscillator, baud
rate generator, and digital phase-locked
loop on each channel
• Processing speeds up to 4 Mbps
• Multi-protocol format (async, monosync,
bisync, SDLC/HDLC, SDLC/HDLC loop)
• Encodes in the following modes: NRZ, NRZI,
FM0, FM1, and Manchester
• CRC-16 or CRC-CCITT error detection
• 1-byte transmit FIF0/3-byte receive FIF0
• 2 transmit and 2 receive DMA channels (16C35 only)
Increasing speed
The standard and integrated universal serial con-
trollers Z16C30, Z16C35, and Z16C32 offer faster
performance. Features include:
• Dual full-duplex channels (Z16C30)
• Single full-duplex channel (Z16C32)
• Accommodates two baud rate generators
and one digital phase-locked loop
(on each channel)
• 2 DMA control signals per channel
(Z80C30/Z85C30 only)

Simplifying software
The enhanced dual and mono SCCs Z80230, Z85230, and
Z85233, include many features that make programming
easy. These parts also reduce CPU overhead, allowing the
programmer to select packet handling response and
improve cycle access recovery time. Features include:
• Dual full-duplex channels (Z80230/Z85230)
• Single full-duplex channel (Z85233 only)
