I'm planning to buy a Z8018006PSC. A z180 CPU (which I found is compatible with the z80 and has some advantages, for instance, able to address up to 1MB of RAM).
I'm planning to use it together with a 3.3v FPGA to generate its clock (so it can be "variable").
I just want to know if I'm reading the documentation right. On the absolute maximum ratings it can be run from -0.3v to +7.0v. So I can drive directly with 3.3v? And the input ports have a tolerance of vcc + 0.3v, so at 3.3v i will be able to put up to 3.6v on any input port?
Of course, it will not run stably at 6MHz, but something close to 1MHz~2MHz will be fine for my purposes.
