Capabilities
Unlike the PSG which was a tone-generating chip, the SCC is a simple wavetable sound chip. The chip has 128 bytes of memory built in, combined from 4 wave samples of 32 bytes each. Each of 3 channels gets its own sample, and channels 4 and 5 share a sample. Each channel can be controlled by an on/off bit, volume, and frequency.
Though 32 bytes at most resolutions does not represent a complicated sample, such as a guitar recording, the 32 bytes were usually used to construct synthetic instruments with waveforms far more complex than what the PSG tone generators could produce.
The chip produced it's sound at an unparalleled sample rate of 3.57MHz, much higher than today systems of 48KHz or 96KHz.
It also had a memory mapper built in, so the cartridges only needed this chip and the actual ROM. Only a few of the MSX/MSX2 used this chip. The first of all was Gradius 2. Games like Gradius or Yie-Are Kung-Fu were produced using the PSG sound chip but they were re-launched using the SCC chip improving their sound quality.
A slightly improved version called the SCC+ is used for Snatcher and SD Snatcher, which has 64kB of RAM on-board and minor improvements.

Famous quotes containing the word capabilities:
“I maintain that I have been a Negro three times—a Negro baby, a Negro girl and a Negro woman. Still, if you have received no clear cut impression of what the Negro in America is like, then you are in the same place with me. There is no The Negro here. Our lives are so diversified, internal attitudes so varied, appearances and capabilities so different, that there is no possible classification so catholic that it will cover us all, except My people! My people!”
—Zora Neale Hurston (1891–1960)
