The '''80188''' variant, with an [[8-bit]] external [[data bus]] was also available; this made it less expensive to connect to [[peripheral]]s. The 16-bit registers and the one [[megabyte]] address range were unchanged, however. It had a throughput of 1&nbsp;million [[instructions per second]].<ref>{{cite web|url=http://www.depi.itch.edu.mx/apacheco/asm/Intel_cpus.htm#186 |title=1.3 La familia de microprocesadores de Intel. |trans-title=Intel Processors: MCS-4, MCS-8, MCS-85, x86: IA-16, IA-32, IA-64. |author=Pacheco, Alberto |date=October 12, 2001 |work=CB-00-852/01.

The 80188 series was generally intended for [[embedded system]]s, as [[microcontroller]]s with external memory. Therefore, to reduce the number of chips required, it included features such as [[clock generator]], [[interrupt controller]], timers, [[wait state]] generator, [[Direct memory access|DMA]] channels, and external [[chip select]] lines.
While the N80188 was compatible with the 8087 numeric co-processor, the 80C188 was not. It did not have the ESC control codes integrated.
