YMF289B-F

The YMF289B-F is designed as a synthesizer chip developed specially for more PC, PCMCIA (type II) card. It is compatible with YMF262 which is de facto standard in sound card market. Special functions (power diwn mode, 3.3V power supply and etc.) are newly featured.

YMF289B-F has seven features. (1)Register-compatible with YMF262. (2)Sampling frequency is 44.1KHz. (3)All registers are readable. (4)Supports low power consumption mode (power down mode). (5)5V or 3.3V power supply. (6)DAC interface compatible with YAC516 and YAC513. (7)44-pin QFP package. Those are all the main features.

Some absolute maximum ratings of YMF289B-F 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. It should be noted that stresses above those listed in absolute maximum ratings may cause permanent damage to device.

Also some electrical characteristics of YMF289B-F are concluded as follow. (1)Its power consumption would be max 150mW at Vdd=5.0V and would be max 60mW at Vdd=3.3V. For power down mode it would be max 300uW at Vdd=5.0V and max 200uW at Vdd=3.3V. (2)Its input high level voltage would be min 2.0V and would be min 0.7Vdd for power down mode. (3)Its input low voltage would be max 0.8V and would be max 0.2Vdd for power down mode. (4)Its input leakage current would be min -10uA and max 10uA. (5)Its input capacitance would be max 10pF. (6)Its output high level voltage would be min Vdd-1.0V and would be min 2.4V for power down mode. (7)Its output low level voltage would be max Vss+0.4V and it would be max 0.4V for power down mode. And so on. If you have any question or suggestion or want to know more information please contact us for details. Thank you!
