The 80188 is a highly-integrated microprocessor with an 8-bit data bus interface and a 16-bit internal architecture for high performance. It effectively combines 15-20 of the most common iAPX 86 system components onto one. The 8 MHz 80188 provides two times greater throughput than the standard 5 MHz 8088. The 80188 is upward compatible with 8086 and 8088 software and adds 1 0 new instruction types to the existing set.
