** Yamaha YM2413 ( a. k. a. OPLL ), used in MSX in MSX Music cartridges like the FM-PAC and internally in several Japanese models by Panasonic, Sony and Sanyo ; also used in Sega Mark III ( Japanese version of Master System )

** Yamaha YM2612 ( a. k. a. OPN2 ), used in Sega Mega Drive / Genesis

** Sega Master System ( 1989 ), stereoscopic version titled OutRun 3-D which supports SegaScope 3-D Glasses.

** RF5c68 and RF5c164 ( Sega CD PCM )

** Sega SuperStars ( Sega )

** Differential PCM ( DPCM )

** MR-1000-1bit 5. 6448 MHz / 1bit 2. 8824 MHz ( DSD )/ 24bit 192 kHz ( PCM )

** OggPCM-an encapsulation of PCM audio data inside the Ogg container format

** A lossless " PCM macroblock " representation mode in which video data samples are represented directly, allowing perfect representation of specific regions and allowing a strict limit to be placed on the quantity of coded data for each macroblock.

** An enhanced lossless macroblock representation mode allowing perfect representation of specific regions while ordinarily using substantially fewer bits than the PCM mode.

** Pulse-code modulation ( PCM )

** WAV container, uncompressed PCM

** megaAVRs with special features not found on the other members of the AVR family, such as LCD controller, USB controller, advanced PWM, CAN etc.

** PWM output ( some devices have an enhanced PWM peripheral which includes a dead-time generator )

The Sega Saturn also with a CD drive supported 32 channels of PCM at the same resolution as the PSX.

Later on, modders found out that a caseless 32x can fit in a Genesis Model 2 case with the Genesis itself, thus, a homemade Sega Neptune.

" Eventually designs evolved beyond what the Sega 32x was capable of, and the system itself was struggling sales-wise, so the game, among many in development for the system, was shifted to the Sega Saturn console.

* Audio: Stereo 10-bit PWM ( Pulse Width Modulation ) mixing with Mega Drive / Genesis sound for a total of 12 audio channels of varying capability, 20 with the addition of a Mega-CD / Sega CD.

Unlike pulse-width modulation (" PWM "), which turns a signal on and off, pulse-code modulation also allows the level of a signal to be set to several intermediate levels ; in this regard, PWM and PCM are similar to black-and-white and grayscale images, respectively.
