General Description
PS011705-0608
The Z80C30/Z85C30 Serial Communications Controller (SCC), is a pin and software
compatible CMOS member of the SCC family introduced by Zilog
channel, multi-protocol data communications peripheral that easily interfaces with CPU’s
with either multiplexed or non-multiplexed address/data buses.
The advanced CMOS process offers lower power consumption, higher performance, and
superior noise immunity. The programming flexibility of the internal registers allow the
SCC to be configured to various serial communications applications.

The many on-chip features such as Baud Rate Generators (BRG), Digital Phase Locked
Loops (DPLL), and crystal oscillators reduce the need for an external logic.
Additional features include a 10 x 19-bit status FIFO and 14-bit byte counter to support
high speed SDLC transfers using DMA controllers.
The SCC handles asynchronous formats, synchronous byte-oriented protocols such as
IBM Bisync, and synchronous bit-oriented protocols such as HDLC and IBM SDLC. This
device supports virtually any serial data transfer application (for example, cassette,
diskette, tape drives, etc.).
The device generates and checks CRC codes in any synchronous mode and can be
programmed to check data integrity in various modes. The SCC also contains facilities for
modem controls in both channels. In applications where these controls are not required,
the modem controls can be used for general-purpose I/O. The daisy-chain interrupt hierar-
chy is also supported.
