What the N80C188-16 is and where it fits
The Intel N80C188-16 is a 16-bit microprocessor from the i186 family, built around the 80C186 core. It runs at 16 MHz with a 16-bit external bus and integrates a DRAM controller, making it a single-chip CPU for embedded x86 designs that need to talk directly to DRAM without an external memory controller. The 5.0V I/O voltage matches legacy 5V logic and peripheral families. Typical applications include industrial controllers, telecom line cards, and office-equipment motherboards where the commercial temperature range (0°C to 70°C) is acceptable — this part is not rated for extended or automotive environments.
16 MHz clock and 16-bit bus — what they mean for your BOM
The 16 MHz clock sets the bus cycle time. The integrated DRAM controller works with standard DRAM.
