The Sega MultiPCM (Yamaha part number: YMFA1005, Sega part number: 315-5560), also called as Yamaha YMW-258-F is a custom sound chip made by Yamaha for use in Sega's arcade machines, namely the Sega System Multi 32, Sega Model 1 and Sega Model 2.

The sound chip is a stripped-down version of an already existent sound chip made by Yamaha, the YMF278B, known for their MoonSound cartridge fame, the primary difference being the lack of FM channels inside the MultiPCM; it only contains PCM channels. This sound chip has a total of 28 PCM channels.

In Sega games, the MultiPCM is used with a Yamaha YM3438 sound chip (a CMOS version of YM2612), however, their purpose on these games are only for sound timer controlling.

In vgmplay.ini MultiPCM can be configured in the [MultiPCM] section.
