The Z16C30 USC鈩?Universal Serial Controller is a dual-
channel multi-protocol data communications peripheral de-
signed for use with any conventional multiplexed or non-
multiplexed bus. The USC functions as a serial-to-parallel,
parallel-to-serial converter/controller and may be software
configured to satisfy a wide variety of serial communica-
tions applications. The device contains a variety of new, so-
phisticated internal functions including two baud rate gen-
erators per channel, one digital phase-locked loop per

channel, character counters for both receive and transmit in
each channel and 32-byte data FIFO鈥檚 for each receiver and
transmitter (Figure 1).
ZiLOG now offers a high speed version of the USC with
improved bus bandwidth. CPU bus accesses have been
shortened from 160 ns per access to 110 ns per access. The
USC has a transmit and receive clock range of up to 10 MHz
