PC Engine Chip Pinouts
This data was taken from numerous places. Special thanks to the usual PCE crew: Chris Covell, bt garner, Joann, and also to Backup Technik/GameLab magazine, from which I occasionally learned something new.
Conventions used
Throughout this page you'll find abbreviations and shorthand terms for a lot of connections. Here's a guide:
Short | Long | Short | Long |
---|---|---|---|
Dxx | Data (number) | Axx | Address (number) |
/WR | Write Enable | /OE | Output Enable |
/CE | Chip Enable | NC | Not Connected |
I/O | Input/Output | RAxx | RAM pin# |
- Misc ICs are the two RAM chips (numbered 1, 2, and 12 for both)
The NetList
Someone once told me that when you make a list of connections on a circuit it's called a netlist. So here's the netlist for each chip.
