YM2151

The YM2151 is an FM-type sound generator equipped with an 8 bit bus line and capable of producing superb audio quality via a microprocessor program. When this IC is used in tandem with the specially-developed YM3012D/A converter, you can obtain 8-note, left-right/2-channel audio signals.In addition, this unit is equipped with noise, vibrato, an amplitude modulation circuit, a sound effects circuit,and timer.The package is a 24-pin dual in-line package.

Features of the YM2151 are:(1)generate up to 8 notes; (2)generate noise; (3)timbre can be altered temporally; (4)high harmonic can be de-hermonized from the base frequency; (5)de-harmonize between octaves; (6)interval setting of up to 1.6 cents; (7)add vibrato and amplitude modulation; (8)generate a variety of sound effects by extreme deharmonization of the high harmonic from the base frequency and massive vibrato and amplitude modulation.

The absolute maximum ratings of the YM2151 can be summarized as:(1)terminal voltage:-0.3 to 7.0 V;(2)storage temperature:-50 to +125;(3)operating ambient temperature:0 to +70.The information given herein, including the specifications and dimensions, is subject to change without prior notice to improve product characteristics.
