General Description
The IA88COO is a form, fit and function replacement for the original Zilog® Z88C00 microcontroller.
Innovasic Semiconductor produces replacement ICs using its MILES
TM
, or Managed IC Lifetime
Extension System, cloning technology. This technology produces replacement ICs far more complex than
"emulation" while ensuring they are compatible with the original IC. MILES
TM
captures the design of a
clone so it can be produced even as silicon technology advances. MILES
TM
also verifies the clone against
the original IC so that even the "undocumented features" are duplicated.
This Data Sheet documents all necessary engineering information about the IA88COO including
functional and I/O descriptions, electrical characteristics, and applicable timing.
The function block diagram of the IA88C00 is shown in Figure 1. The device is available in a 48-pin DIP
(Figure 2) and a 68-pin PLCC package (Figure 3). The pin functions of the IA88COO are outlined in
Figure 6. Pin Functions.
