81 / 113 page  MB90480/485 Series 81 2. Recommended Operating Conditions (VSS = AVSS = 0.0 V) * : MB90485 series only P20 to P27, P30 to P37, P40 to P47, P70 to P77 pins can be used as 5 V I/F pin on applied 5 V to VCC5 pin. WARNING: The recommended operating conditions are required in order to ensure the normal operation of the semiconductor device. All of the device’s electrical characteristics are warranted when the device is operated within these ranges. Always use semiconductor devices within their recommended operating condition ranges. Operation outside these ranges may adversely affect reliability and could result in device failure. No warranty is made with respect to uses, operating conditions, or combinations not represented on the data sheet. Users considering application outside the listed conditions are advised to contact their FUJITSU representatives beforehand.
