Sorry if I'm posting in the incorrect place. I'm new and trying to figure this forum and the ways things are done here.
In there it states this: - There is unknown device (Sony CXK5808-55) on the board.
I've been searching for info on this IC and have found it in the Ghosts n Goblins schematic.
It is a 1k x 8 RAM (I'm not 100% sure if it's considered bipolar or static...) in a 22 pin package. It's not in ChipDir or out on any of the datasheet sites I've found yet. Sony has no old datasheets on it either.
Code:
The pinout is this:
A6 - 1 22 - Vcc A5 - 2 21 - A7 A4 - 3 20 - A8 A3 - 4 19 - A9 A2 - 5 18 - /CE A1 - 6 17 - /WE A0 - 7 16 - D7 D0 - 8 15 - D6 D1 - 9 14 - D5 D2 - 10 13 - D4 Gnd- 11 12 - D3
It's funny... Capcom used only 256 x 8 in that chip. The upper 2 address lines are grounded.
