Description

The YMU277 is a low-voltage operation custom LSI for automatic playback employing FM sound source.There are some features as follows.First is realistic sound by 2 operator FM sound source.The second is 3-octave sound range.Besides,up to 4 sounds with different timbres can be generated.Then is musical performance data for up to 4 melodies within 255 steps.Furthermore,up to 4 timbres can be set for 1 melody (or 1 phase).The sixth is maximum of 8 timbre presets for 8 melodies.The seventh is binary and serial melody selection modes.The eighth is built-in DAC and crystal oscillator circuit.The ninth is that level hold or one shot playback is possible.The tenth is stand-by mode.The last one is low power consumption realized by silicon gate CMOS process.

What comes next is about the absolute maximum ratings YMU277.The VDD (power supply voltage) is from -0.3 V to +0.7 V.The Top (operating temperature) is from -20 to +85.The Tstg (storage temperature) is from -50 to +125.Then is about the recommended operating conditions.The minimum VDD (power supply voltage) is 2.4 V,the typical is 3.0 V and the maximum is 5.25 V.The VSS (power supply voltage) is 0 V.

The following is about the DC characteristics (conditions: Ta=0 to 70,VDD=2.4 to 5.25 V) YMU277.The maximum IDD (current consumption) is 3.0 mA at VDD=5.0 V, 1.8 mA at VDD=3.0 V and 1.5 mA at VDD=2.4 V.The maximum IDD (current consumption (standby mode)) is 5.2A at VDD=5.0 V, 1.8A at VDD=3.0 V and 1.8A at VDD=2.4 V when input voltage of XI,/ST,/PR,MD,SC,S0,S1, and /TI pin is high level.The minimum II1 (input current) is 0.5A and the maximum is 15A at VI= 0 V applied to XI pin.The minimum II2 (input current) is 30A and the maximum is 100A at VI= 0 V applied to /ST,/PR,MD,SC,S0,S1, and /TI pin.
