Revision A edition of the PG9732 datasheet, an 88.2 KB PDF and probably the earliest sheet in this series. Its base number points to a 97 by 32 dot graphic LCD module. The document should give general pinout, voltages, timing and dimensions shared by the family. Because later revisions B, C and D also exist, values may have been corrected since, so prefer the newest one when they conflict. Always confirm the part code on the module itself before using any figure for diagnosis.
