GENERAL DESCRIPTION
The Z86C3X/C40 Consumer Controller Processors
(CCP) are members of the Z8® single-chip microcontroller
family offering a unique register-to-register architecture
thatavoidsaccumulatorbottlenecksandoffersfastexecu-
tion of code.
Two on-chip counter/timers, with a large number of select-
able modes, offload the system of administering real-time
tasks such as counting/timing and I/O data communica-
tions.
With ROM/ROMless selectivity, the Z86C40 provides both
external memory and pre-programmed ROM, which
enables these Z8 microcontrollers to be used in high-
volume applications, or where code flexibility is required.
Three address spaces (Program Memory, Register File,
and Expanded Register File [ERF]), support a wide range
of memory configurations. Through the ERF, the designer
has access to three additional control registers that pro-
vide extra peripheral devices, I/O ports, and
register addresses. The rest of the ERF is not physically
implemented and is open for future expansion.
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).
Power connections follow conventional descriptions below:
For applications demanding powerful I/O capabilities, the
Z86C3X/C40's dedicated input and output lines are
grouped into three and four ports, respectively, and are
configurable under software control to provide timing,
status signals, or parallel I/O.
