The Ricoh RF5c68 is an eight-channel sound chip developed by Ricoh. It is notably used in Fujitsu's FM Towns computer series, along with Sega's System 18 and System 32 arcade game system boards.
The RF5c68 supports eight 8-bit PCM channels, with 19.6 kHz or variable sampling rate. Audio bit depth ranges from 8-bit to 10-bit.
A similar (but not identical) sound chip to the RF5c68 was the RF5C164, used in the Sega Mega-CD.
