You can try contact owner of this web for translating to english.
I think, that HD46502 is 6502 CPU.

from one of his other pages
| Quote: | Hitachi HD46503 Motorola's M6800 is a flexible controller that can interface directly to system bus. Motorola in the FDC system, only it's it.
As you can guess from the model number HD46503 HD46502 (compact magnetic tape drive), HD46504 (Direct), HD46505 (CRT display controller) was released with.
Of these, HD46502 has no second source, HD46504 is MC6844, HD46505 is a Motorola MC6845 was also provided.
HD46503 from the Motorola MC6843 but this seems to have been supplied with a second source model that has yet to see real.
HD46505 and HD46504 addition of 1 MHz clock version, 1.5 MHz 2 MHz and is also available in versions, HD46503 seems to be missing for the 1 MHz clock version only. |
I suspect it is not a 6502 but a custom IC

Hi,
HD46502 is a controller chip for a tape drive and has nothing to do with the 6502 processor.
Hitachi developed several peripheral chips named HD4650x, such as the HD46504 DMA controller and the HD46505 CRT controller.
They are second sourced by Motorola as MC6844 and MC6845, respectively.

I hope it is a 6502 cpu but it is not.
I am asking here just for confirmation.
thanks for your kind replies
