STw8009/STw8019

Functional description

17/55

Transition from Active mode to Sleep mode

In Sleep mode, DENC is not powered on. When Suspend signal changes from « 0 » to

« 1 », the device goes from Active to Sleep mode and an internal Reset signal is generated

by the Control Power Unit management to the DENC part. This signal has a 6 pixclk

duration (pixclk = 27 MHz).

Transition between Standby and Active modes

Transitions between these two modes are applied by software configuration through I2C

interface.

Supply management

At power up, supplies must be applied according to the following sequence:

VddIO1, VddIO2 (1.8 V) then,

Vdd (1.2 V) then,

VccA1, VccA2, VccA3, VccA4 (2.8 /3.3 V)

and removed according to the following sequence:

VccA1, VccA2, VccA3, VccA4 (2.8 /3.3 V) then,

Vdd (1.2 V) then,

VddIO1, VddIO2 (1.8 V)
