t_sup_del

For proper operation of internal reset functions, VCCA and

VCCD (which must be applied simultaneously) may not be

applied after VCCmod.

Normally, all VCC lines will come up at the same time.

However, due to the possibility of a Standby VCC to be

applied to the VCCmod pin, care should be ensured that

time

VCCmod is not applied before VCCA and VCCD (which must be

tied together). See the timing diagram and DATA

RETENTION function description.

Note that VCCA/D and VCCmod must be activated above 4.5

V for a least 30 msecs before the device can operate

correctly in Standby Mode.
