Here three unknown Sharp ICs are shown.
Two chips marked as SHARP 50752B26B2 F0703T588 and one marked as RX-IX0032YCPZQ I've found almost nothing about these chips on the net. What can it be? |

Thank you for explanation!
QUOTE Just a plain custom programmed 8MiB PROM with bootloader, ROM diag and EN-JP dictionary database. So, if I understand correctly, it contains initial bootloader that execute code from NAND and diagnostic menu code, doesn't it? |

And probably more (debugging monitor?), but there is no documentation. |
