Starting with GH-026, the SSBUS controller and the SPU2 were combined into a single chip (CXD2955R), until the SSBUS controller functionality ultimately became obsolete with the introduction of the L-chassis (SCPH-750XX, GH-036 and newer), | Starting with GH-026, the SSBUS controller and the SPU2 were combined into a single chip (CXD2955R), until the SSBUS controller functionality ultimately became obsolete with the introduction of the L-chassis (SCPH-750XX, GH-036 and newer), hence the switch way back to CXD2947R that was introduced with GH-017. | ||
Starting with GH-061, the SPU2 was integrated into the new main SoC ([[Emotion Engine#Revisions|CXD2976GB]]) and does not exist as a dedicated IC anymore. | Starting with GH-061, the SPU2 was integrated into the new main SoC ([[Emotion Engine#Revisions|CXD2976GB]]) and does not exist as a dedicated IC anymore. | ||
