GENERAL DESCRIPTION
The Z80181 SAC
Smart Access Controller (hereinafter,
referred to as Z181 SAC) is a sophisticated 8-bit CMOS
microprocessor that combines a Z180-compatible MPU
(Z181 MPU), one channel of Z85C30 Serial Communica-
tion Controller (SCC), a Z80 CTC, two 8-bit general-pur-
pose parallel ports, and two chip select signals, into a
single 100-pin Quad Flat Pack (QFP) package (Figures 1
and 2). Created using Zilog's patented Superintegration
methodology of combining proprietary IC cores and cells,
this high-end intelligent peripheral controller is well-suited
for a broad range of intelligent communication control
applications such as terminals, printers, modems, and
slave communication processors for 8-, 16- and 32- bit
MPU based systems.
Information on enhancement/cost reductions of existing
hardware using Z80/Z180 with Z8530/Z85C30 applica-
tions is also included in this product specification.
Notes:
All Signals with a preceding front slash, "/", are active Low, e.g.,
B//W (WORD is active Low); /B/W (BYTE is active Low, only).
