GENERAL DESCRIPTION
The Z16COl/CO2 CPU are members of the 16-bit
processor and controller family. Designed using a
RISC-like Load/Store architecture, the CPU can operate in
either system or normal modes, permitting privileged
operations and improving operating system organization
and implementation.
s
To boost the main CPU’ performance capability, the
processor core includes hardwired control and is a
16-bit real-time processor functioning at register access
speeds. Register flexibility is created by grouping or
overlapping multiple registers, and by allowing extended
register file capabilities as the system expands. Easy
extended register file control is accomplished through a
single instruction stream communication.
TheCPUsupportsthreetypesof interrupts (non-maskable,
vectored, and non-vectored) and four traps (system call,
extended process architecture instruction, privileged
instructions, and segmentation trap). The vectored and
non-vectored interrupts are maskable.
The processor’ resources include seven data types that
s
range from bits to 32-bit long words, and byte and word
strings, plus eight user-selectable addressing modes. The
nine basic instruction types can be combined with various
data types and addressing modes to form a powerful set
of 414 instructions.
The extended processing architecture features provide a
modular approach to expanding both the hardware and
software capabilities of the Z16COl/CO2.
Notes:
All Signals with a preceding front slash, “/“, are active Low, e.g.:
B/AN(WORDis active Low);
/B/W^(BYTE
is active Low, only).

Stresses greater than those listed under Absolute Maxi-
mum Ratings may cause permanent damage to the de-
vice. This is a stress rating only; operating of the device at
any condition above these indicated in the operational
sectionsof these specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods
may affect device reliability.
STANDARD TEST CONDITIONS
The DC characteristics below apply for the following test
conditions, unless otherwise noted. All voltages are refer-
enced to GND (OV). Positive current flows into the refer-
enced pin.
Available operating temperature ranges are:
s = 0°C to +7O”C, + 4.5v s V,,I
(Z16COi,Zl6CO2)
E = -4OOC to +lOO”C, + 4.5V IV&
(Z16CO1, Zi 6CO2)
+ 5.5v
+ 5.5V
All AC parameters assume a total load capacitance
(including parasitic capacitances) or 100 pf max, except
for parameter 6 (50 pf max). Timing reference between two
output signals assume a load difference of 50 pf max.
The Ordering Information section lists package tempera-
ture ranges and product numbers.
