GENERAL DESCRIPTION
The Z86C61/62/96 microcontroller is a member of the Z8
single-chip microcontroller family with 16 Kbytes of ROM
and 256 bytes of RAM. The Z86C96 is ROMless.
The Z86C61 is offered in 40-pin DIP and 44-pin PLCC style
packages, however, the ROMless pin option is available
on the 44-pin version only. The Z86C62/96 is offered in 64-
pin DIP and 68-pin PLCC style packages. A ROMless pin
option enables these MCUs to address both external
memory and preprogrammed ROM, making them well-
suited for high-volume applications or where code flexibil-
ity is required.
With 16 Kbytes of ROM and 256 bytes of general-purpose
RAM, these low-cost, low power consumption CMOS
Z86C61/62/96 MCUs offer fast execution, efficient use of
memory, sophisticated interrupts, input/output bit manipu-
lation capabilities, and easy hardware/software system
expansion.
The Z86C61/62/96 architecture is characterized by Zilog’s
8-bit microcontroller core. The device offers a flexible I/O
scheme, an efficient register and address space structure,
multiplexed capabilities between address/data, I/O, and a
number of ancillary features that are useful in many indus-
trial and advanced scientific applications.
For applications which demand powerful I/O capabilities,
the Z86C61 fulfills this with 32 pins dedicated to input and
output. These lines are grouped into four ports with eight
lines each. The Z86C62/96 has 52 pins for input and
output, and these lines are grouped into six, 8-bit ports and
one 4-bit port. Each port is configurable under software
control to provide timing, status signals, serial or parallel
I/O with or without handshake, and an address/data bus
for interfacing external memory.
