CHMOS 16-BIT MICROCONTROLLER
Automotive
The
8xC196EA
is the first member of a new family of microcontrollers with features that are useful in
automotive applications, such as powertrain control. Two Mbytes of linear address space provide more space
for high-level language compilation. A demultiplexed address/data bus and three chip-select signals make it
easier to design low-cost memory solutions. The external bus can dynamically switch between multiplexed
and demultiplexed operation.
NOTE
This datasheet contains information on products being sampled or in the initial production
phase of development. The specifications are subject to change without notice. Verify
with your local Intel sales office that you have the latest datasheet before finalizing a
design.
