YMZ263B

The YMZ263B is designed as one kind of multimedia audio and game interface controller. We have successfully packaged in a single chip features like PCM / ADPCM record and playback, MIDI communications, and a general purpose game port. This device is now possible to create a compact, personal computer based sound system by combining it with the YM3812 and the YMF262.

Features of the YMZ263B are:(1)selectable PCM / ADPCM modes;(2)two built-in recording and playback channels;(3)PCM has 8-bit or 12-bit resolution, ADPCM compresses 12-bit data into 4-bits;(4)built-in 12-bit floating A/D and D/A converters for record and playback;(5)2-channel and double over-sampling A/D conversion;(6)UART for sending and receiving data that meets MIDI standards;(7)separate built-in 16-byte FIFO buffers for sending and for receiving;(8)eight input ports for interfacing joysticks, etc.;(9)three built-in timers;(10)built-in address decoder.

The absolute maximum ratings of the YMZ263B can be summarized as:(1)power supply voltage: -0.3 V to +7.0 V;(2)input voltage: -0.3 V to VDD+0.5 V;(3)operating temperature: 0 to 70 ;(4)storage temperature: -50 to +125 .
