YMF704C

YMF704C (OPL4-ML) is a Wave table synthesizer LSI that intergrates OPL3, General MIDI processor and Wave table ROM into one chip and complies with GM system level 1.It makes a low cost system with high quality tone when it is used in the multimedia personal computors and boards.The LSI is able to operate normally at power voltage of 3.3 V.These features make this LSI suitable for notebook type personal computers that require low power consumption.

What comes next is about the absolute maximum ratings of YMF704C.The VDD (power supply voltage) is from -0.3 V to +7.0 V.The VI (input voltage) is from -0.3 V to VDD+0.5 V.The Top (operating temperature) is from 0 to +70.The Tstg (storage temperature) is from -50 to +125.Then is about the recommended operating conditions.The minimum VDD (power supply voltage) is 4.75 V,the typicall is 5.00 V and the maximum is 5.25 V when 5 V/3 V='H'.The minimum VDD (power supply voltage) is 3.00 V,the typicall is 3.30 V and the maximum is 3.60 V when 5 V/3 V='L'.The minimum Top (operating temperature) is 0,the typical is 25 and the maximum is 70.

The following is about the DC characteristics of YMF704C (under recommended operating conditions).The maximum PD (power dissipation) is 300 mW at VDD=5.25 V at operation and is 150 mW at VDD=3.60 operation.The minimum VIH1 (high level input voltage) is 2.0 V and the maximum VIL1 (low level input voltage) is 0.8 V  for input pins except XI, 5 V/3 V and ADB0-ADB7.The minimum VIH2 (high level input voltage) is 0.7VDD V and the maximum VIL2 (low level input voltage) is 0.2VDD V for XI, 5 V/3 V.The minimum ILI (input leakage current) is -10 A and the maximum is 10 A at 0 VVINVDD V.The maximum CI (input capacitance) is 10 pF.The maximum CO (output capacitance) is 10 pF.
