GENERAL DESCRIPTION
ZiLOG鈥檚 Z8
廬
MCU single-chip family now includes the
Z86C34/C35/C36/C44/C45/C46 product line, featuring en-
hanced wake-up circuitry, programmable Watch-Dog Tim-
ers (
WDT
), and low-noise/EMI options. Each of the new en-
hancements to the Z8 offer a more efficient, cost-effective
design and provide the user with increased design flexibility
over the standard Z8 microcontroller core. The low-power
consumption CMOS microcontroller offers fast execution,
efficient use of memory, sophisticated interrupts, input/out-
put bit manipulation capabilities, and easy hardware/soft-
ware system expansion.
The Z8 subfamily features an Expanded Register File (
ERF
)
to allow access to register-mapped peripheral and I/O cir-
cuits. Four basic address spaces are available to support this
wide range of configurations: Program Memory, Register
File, Data Memory, and
ERF
. The Register File is composed
of 236/237 bytes of general-purpose registers, four I/O port
registers, and 15 control and status registers. The
ERF
con-
sists of twelve control registers.
For applications demanding powerful I/O capabilities, the
Z86C34/C35/C36 offers 24 pins, and the Z86C44/C45/C46
offers 32 pins dedicated to input and output. These lines are
