MAXIMUM RATINGS at V
SS
= 0 V, T
A
= +25°C (Note 3)
Note 3 : Stresses exceeding those listed in the Absolute Maximum Rating table may damage the device. If any of these limits are exceeded,
device functionality should not be assumed, damage may occur and reliability may be affected.
4 : Apply to Cin0 to Cin7, CMAdd0, CMAdd4, Cref, CrefAdd ,SCL/SCK ,SDA/SI ,SA0, nCS, nRST, IFSEL.
5 : Apply to Cdrv, CdrvBar, SDA, SO, INTOUT, Tout0 to Tout4.
6 : Total value with duty cycle under 25%.
7 : Limited to one pin, with duty cycle under 50%.

RECOMMENDED OPERATING RANGES at V
SS
= 0 V (Note 9)
Note 9 : Functional operation above the stresses listed in the Recommended Operating Ranges is not implied. Extended exposure to
stresses beyond the Recommended Operating Ranges limits may affect device reliability.
10 : For noise de-coupling place a high-valued capacitor and a low-valued capacitor in parallel between V
DD
and V
SS
. The small-valued
capacitor, at least 0.1 μF, should be mounted near the LSI. In addition, it is recommended that the power supply ripple + noise is
less than 40 mV.
11 : Apply to SCL/SCK ,SDA/SI ,SA0, nCS, nRST, IFSEL.
