The 20 MHz clock sets the timing for bus cycles and DRAM refresh. At this speed, wait states may be needed with slower EPROM or peripheral devices — the datasheet's AC timing tables should be consulted for setup/hold margins. The on-chip DRAM controller handles the refresh overhead, which simplifies the board layout but ties the designer to the supported DRAM types listed in the controller's configuration registers.

The S80C186-20 is a 16-bit microprocessor with a 20 MHz clock, 5.0V I/O, integrated DRAM controller, and a commercial temperature range of 0°C to 70°C. It has a single core with a 16-bit data bus.
The S80C186-20 is functionally equivalent to the 80C186-20 — the 'S' prefix denotes an Intel standard product variant. It can be used as a direct replacement in designs that call for the 80C186-20, provided the package and pinout match.
The S80C186-20 is rated for 0°C to 70°C ambient, suitable for commercial indoor environments.
The 80C186 has a full 16-bit external data bus; the 80C188 uses an 8-bit multiplexed bus. They are not pin-compatible without board-level changes.
