Hi,

It seems not new.

YMF825 (SD-1)

  • Year of release: 2011
  • FM: 16 channels (4-op, 29 waveforms)
  • Used in: Home appliances (Chinese market)

This appears to be a version of MA-3. It has no PCM or Analog Lite capabilities. Using 2-op instruments does not give extra channels, thus it's probably best to use 4-op instruments.
