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.
