The Namcot 129 and 163 seem to be identical. The Namcot 175 and 340 have minor but vital differences.

05 also connects to CIRAM A10
19,32,43 Some boards connect a battery (through a standard diode switch) to this pin to make the waveform memory nonvolatile
22 Some boards this is connected to +5V, some to Gnd, so probably an input
30 pull-down resistor present on boards with battery for low-power mode
33 Ground this pin with if CHR's nOE and nCS lines are separate
34 Probably an input instead of a power supply, can't find an example of it being used
40 6264 /CE connected to this pin
44 Might be an enable for CHR RAM, can't find an example of it being used
