Description：
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 development 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 programming easy. These parts also reduce CPU overhead, allowing the programmer to select packet handling response and improve cycle access recovery time. 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)
• Encodes in the follow modes: NRZI, FM0, FM1
and Manchester
• 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)
16-bit Solutions
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:
• Single (Z16C32) and dual (Z16C30)
full-duplex channels
• 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)
