C80186 - Intel 80c186-series Compatible Microcontroller

alt

The C80186 IP core is actually a series of high performance 16-bit microcontrollers designed after a series of 80c186/80c188 designs by Intel® and AM186 implementations from AMD®.

This successful architecture can be applied in all Systems-on- Chips (SoCs) that require higher performance than the one offered by 8-bit designs. The IP core implements the same widely known instruction set architecture as the 80c86 or 80c186  devices, together with extended versions of peripherals set offered by 80c186ec, 80c186xl and 80c186ea microcontrollers.

Moreover, the C80186 can be customized to fit other popular 80c186 derivatives, like AM186ER, AM186ED and AM186ES from AMD®.

Each member of the C80186 family has been enhanced with additional pins to facilitate implementation of the design as an exact pin replacement.
