The prototype of U-110 was called T-110 Multi Timbral Sound Module.

Roland first named U-110's engine as DC-PCM. It's said to mean Different-scale Compounding PCM.
Soon they renamed it as RS-PCM (Resynthesized PCM), when they began to release optional PCM cards and the later U Series.
CM-32P is a white box version of U-110, with only one ROM card slot. CM-64 integrates two synths in the same small package - U-110 and MT-32.
More PCM ROM is added in U-220 and the keyboard version, U-20. There were also other keyboard versions with EP sounds - Roland Rhodes Series - Model 660/760.
Roland CM-64 (1989)
Rhythm machine R-8 Series may be related, as it's a PCM-playback synthesizer with similar expandable ROM cards. Also the 12-bit sampler S-50 Series have PCM playback engine and OS related to U Series.
Later Roland added digital resonant filter to U series, and made D-70 and MV-30.

Roland D-70 (1990)
Roland MV-30 (1990)U Series, CM-32P/CM-64, Rhodes Model 660/760, MV-30 and D-70 can use the same RS-PCM card (SN-U110 series).
