Microprocessors or microcircuits with any of the following conditions are under the ban: (1) Performance speeds reach 5 gigaFlops or higher and an arithmetic logic unit has access width of 32 bits or more; (2) clock frequency rates exceed 25MHz; (3) more than one data or instruction bus or one serial communication port that provide direct external interconnection between parallel microcircuits at a transfer rate of 2.5MB/s.
ICs with more than 144 pins or basic gate propagation delay time of less than 0.4 nanosecond are also prohibited.
Alignment and exposure equipment for wafer production using photo-optical or X-ray methods, such as lithography equipment which includes image projection and transfer, step-and-repeat operation (direct step on wafers) or step-and-scan operation (scanners) processing, as well as scanning electron microscopes designed for automatic inspection of patterns of semiconductor devices are under the ban as well.

(On a personal note - I'm curious what architecture achieves > 5 GFLOPS at 25 MHz )
