'''Intel 80188'''為[[Intel 80186]]的一個衍生版本，跟80186不同的是，它只有一半的[[外部資料匯流排]]（External Data Bus），由16位元減至8位元，以助減低成本。<br />
<br />
80188有四個16位元通用[[暫存器]]，亦可作為八個8位元暫存器。另外，它有十六個16位元的暫存器，包括：[[堆疊指標]]（Stack Pointer）、[[索引暫存器]]（Index registers）以及[[狀態暫存器]]（Status word register）。<br />
<br />
跟[[Intel 8086|8086]]一樣，它同有四個16位元位址暫存器以容許替64千位元組以上的記憶體給予位址。當超越16位元極限（即64KB）時，一個新的數值就會加入。這個位址系統可容許1百萬位元組（1 MBytes）的位址記憶體，但在當時這個數字是比一台電腦所需的[[記憶體]]高出很多。<br />
