High-speed CHMOS technology
The 83C196EA 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.

Figure 1. 83C196EA Block Diagram
The 83C196EA is highly integrated with an enhanced peripheral set. The serial debug unit (SDU) provides
system debug and development capabilities. The SDU can set a single hardware breakpoint and provides
read and write access to code RAM through a high-speed, dedicated serial link. A stack overflow/underflow
monitor assists in code development by causing an unmaskable interrupt if the stack pointer crosses a user-
defined boundary. The 16-channel A/D converter supports an auto-scan mode that operates with no CPU
