i.MX28 Applications Processors for Consumer Products, Rev. 3 2 Freescale Semiconductor Introduction such as memories and SD cards, as well as provide battery charging capability for Li-Ion batteries. After Cyrix was purchased by National Semiconductor in 1997 they terminated their foundry agreement with IBM. National fabricated their own chips and the 6x86MX was re-named MII. We don't have CPU ID information for the Cyrix MII-300GP (66 MHz 2.9V FCPGA) CPU in our database. If you have this processor please use our CPUID tool to submit CPUID information. During submission, please specify family name, MII-300GP (66 MHz 2.9V FCPGA) part number, and, most importantly, make the CPUID record public.

Important: The Cyrix MII and Pentium MMX are dual-voltage processors. This is different from the original Pentium. Use the manual to find the right jumper settings for different CPU voltages. Also, some of these CPUs could potentially draw more power than the board was originally designed for.
