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. 3 MB40C360 ELECTRICAL CHARACTERISTICS * Analog Section (AVDD = 2.7 V to 3.6 V, DVDD = 2.7 V to 3.6 V, VRT = 2.0 V, VRB = 0 V, Ta = -20C to +70C) Parameter Value Symbol Unit Min.

Place the high-frequency capacitor as close as possible to the pin. * You can minimize the power supply current dissipation due to the internal logic indetermination by making the clock to 4CLK or higher.
