Actually there are 2 identical CPU's, and a rather large ASIC made by NEC called an SP70. I assume that there are 2 CPU's as it is a H CPU (and therefore a safety CPU) and the logic is performed by both CPU's simultaneously and if they both come up with the same answer, then all is well, if they don't I expect that a hardware fault is siganalled. Anyway I digress. I cannot find the exact CPU on the Infineon website, but the nearest I can find is http://www.infineon.com/cms/en/product/microcontrollers/legacy-products-c500-c166-xc166-audo1-family/32-bit-tricore/tc1164/channel.html?channel=ff80808112ab681d0112ab6b6dad0823 Which is 80MHz.
