HD64F3437TF16 Datasheet, PDF (581/752 Pages) Hitachi Semiconductor – 12 V must not be applied to the S-mask model (single-power-supply specification), as this may permanently damage the device.

22.4.3 Timing Relationships
Figure 22.2 shows the timing relationships in hardware standby mode.
In the sequence shown, first RES goes low, then STBY goes low, at which point the chip enters
hardware standby mode. To recover, first STBY goes high, then after the clock settling time, RES
goes high.
