Ah, ok. It's strange indeed that GSU-1A is older than GSU-1.nocash wrote:No, I meant, going by the YYWW date codes, GSU-1A is older than GSU-1. That's strange, but I would tend to trust on the date codes there.
MARIO Chip, GSU-1 and GSU-1A all share the same pinout and they all are the same zsize package; well, in fact MC1 package is 19.75mm long and 13.75 mm width and GSU-1 and GSU-1A package are 19.5mm long and 13.5mm width. Anyway, the pin pitch, size and position are the same in all three packages.nocash wrote: Btw. just for curiosity, do you know if there are differences in the pinouts (between the 100pin MC1, GSU1, GSU1A variants, or between the 112pin GSU2, GSU2-SP1 variants)?
The GSU2-SP1 does of course have oddly arranged pins (with pin1 being the SECOND pin and so); but I guess that was done to maintain the same pin numbers as for GSU2.
GSU-2 and GSU-2-SP1 share the same pinout altough pin layout is not the same as you said.
