YMF262-M

The YMF262-M is designed as a sound cource LSI for computer and game equipment. YMF262-M contains an FM sound source which may be controlled by software. In addition, five different rhythm sounds (bass drum, snare drum, tom tom, top cymbal and hi hat cymbal) are available.

YMF262-M has twelve features. (1)Registers are compatible with YM3812 (OPL2) FM sound source. (2)Up to six sounds can be used as four-operator melody sounds for variety. (3)18 simultaneous melody sounds, or 15 melody sounds with five rhythm sounds (with two operators). (4)Six four-operator melody sounds and six two-operator melody sounds, or six four-operator melody sounds, three two-operator melody sounds and five rhythm sounds (with four operators). (5)Eight selectable waveforms. (6)4-channel sound output. (7)YMF262 compatible DAC (YAC512) is available. (8)LFO for vibrato and tremolo effects. (9)Two programmable timers. (10)Shorter register access time compared with YM3812. (11)5V single supply silicon gate CMOS process. (12)24-pin SOP package. Those are all the main features.

Some absolute maximum ratings of YMF262-M have been concluded into several points as follow. (1)Its power supply voltage would be -0.3V to 7.0V. (2)Its input voltage would be from -0.3V to Vdd+0.5V. (3)Its operating temperature range would be from 0°C to 70°C. (4)Its storage temperature range would be from -50°C to 125°C. YMF262-M should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of YMF262-M are concluded as follow. (1)Its power consumption would be max 50mW. (2)Its input high level voltage would be min 2.2V. (3)Its input low voltage would be max 0.8V. (4)Its input leakage current would be min -10uA and max 10uA. (5)Its input capacity would be max 10pF. (6)Its output capacity would be max 10pF. And so on.
