LC786800E no.a2082-13/26 power on and reset control ? attention when power on (1) reset control the resb pin must be set to ?low? level to initialize the operating state of internal flash memory. if the power is switched on when the resb pin is ?high? level, this ic may operate incorrectly because the internal flash memory is not initialized. in this case, this ic is not initialized even if a low level supplied to resb pin. therefore, the resb pin must be set to ?low? level when power is first supplied. (2) electronic volume output because the output state of electronic vo lume pins is undefined when the power voltage is first supplied, it is necessary to mute the electronic volume output signals externally. (3) input voltage for input pins you may input the voltage of 3.6v or less to each input terminal when the power supply is off. however, it is necessary to supply a regulated voltage to the power supply beforehand when more than 3.6v voltage is input to the 5v tolerant input pins. power on/power down/reset timing vbot tpwd tresw1 tresw2 3.3v power v dd 1 3.3v power v dd 1 resb 0v power on stage during normal operation (oscillation clock is valid) parameter symbol min typ max unit power down time tpwd 10 ms power down voltage vbot 0 0.2 v reset time (power on) tresw1 20 ms reset time (normal) (*1) tresw2 1 ms * 1: the x'tal oscillation must be stable during tresw2. when the x'tal clock has been stopped by the command etc., the specification of tresw2 could be longer than the value shown above, because it takes time that the x'tal oscillator becomes stable.
