• Manufacturer Part Number: 83C196EA
• Description: CHMOS 16-BIT MICROCONTROLLER
• Manufacturer: Intel Corporation

1.0 PRODUCT OVERVIEW
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
