UVDDQ: This is the 3.3 V nominal supply for the USB I/O and
some analog circuits. It also supplies power to the USB
transceiver.
VDD: This is the supply voltage for the logic core. The nominal
supply voltage level is 1.8 V. This supplies the core logic circuits.
The same supply must also be used for AVDDQ.
AVDDQ: This is the 1.8 V supply for PLL and USB serializer
analog components. The same supply must also be used for
VDD. Maximum permitted noise on AVDDQ is 20 mV p-p.
XVDDQ: This is the clock I/O supply; 3.3 V for XTAL or 1.8 V for
an external clock.
Noise guideline for all supplies except AVDDQ is maximum
100 mV p-p. All I/O supplies of Arroyo must be ON when a
system is active even if Arroyo is not in use. The core VDD can
also be deactivated at any time to preserve power, provided
there is a minimum impedance of 1 k between the VDD pin and
ground. All I/Os tristate when the core is disabled.

Power Supply Sequence
The power supplies are independently sequenced without
damaging the part. All power supplies must be up and stable
before the device operates. If the supplies are not stable, the
remaining domains are in low power (standby) state.
Power Modes
In addition to the normal operating mode, Arroyo contains
several low power states when normal operation is not required.
Normal Mode
Normal mode is the mode in which Arroyo is fully functional. In
this mode data transfer functions described in this document are
performed.
Suspend Mode
This mode is entered internally by 8051 (external processor only
initiates entry into this mode through Mailbox commands). This
mode is exited by the D+ bus going low, GPIO[0] going to a
pre-determined state or by asserting CE# LOW.
In Arroyo’s suspend mode:
■ The clocks are shut off.
■ All I/Os maintain their previous state.
■ Core power supply must be retained.
■ The states of the configuration registers, endpoint buffers, and
the program RAM are maintained. All transactions must be
complete before Arroyo enters suspend mode (state of
outstanding transactions are not preserved).
■ The firmware resumes its operation from where it was
suspended, since the program counter is not reset.
■ Only inputs that are sensed are RESET#, GPIO[0]/SD_CD,
GPIO[1], SD_D3, D+, and CE#. The last three are wake up
sources (each can be individually enabled or disabled).
■ Hard Reset can be performed by asserting the RESET# input,
and Arroyo is initialized.
Standby Mode
Standby mode is a low power state. This is the lowest power
mode of Arroyo while still maintaining external supply levels. This
mode is entered through deassertion of the WAKEUP input pin
or through internal register settings. To leave this mode, assert
WAKEUP, CE#, and RESET#; and change the state of
GPIO[0]/SD_CD, GPIO[1], or SD_D3.
In this mode all configuration register settings and program RAM
contents are preserved. However, data in the buffers or other
parts of the data path, if any, is not guaranteed in values.
Therefore, the external processor must ensure that the required
data is read before putting Arroyo into the standby mode.
In the standby mode:
■ The program counter is reset on waking up from standby mode.
■ All outputs are tristated and I/O is placed in input only
configuration. Values of I/Os in standby mode are listed in the
pin assignments table.
■ Core power supply must be retained.
■ Hard Reset can be performed by asserting the RESET# input,
and Arroyo is initialized.
■ PLL is disabled.
Core Power Down Mode
The core power supply VDD is powered down in this state.
AVDDQ is tied to the same supply as VDD and is hence, also
powered down. Neither the endpoint buffers, configuration
registers nor program RAM maintain state. It is required that all
VDDQ power supplies (except AVDDQ) are on and not power
downer down in this mode. When UVDDQ is powered down,
D+/D– can’t be driven by external device.
The core power down mode has two power down options:
■ Core only power down – VDD power down.
■ Core and USB power down – VDD and UVDDQ are both
powered down.
In these power down options, the endpoint buffers, configuration
registers, or the program RAM do not maintain state. It is
necessary to reload the firmware on exiting from this mode. It is
required that all VDDQ power supplies are on and not powered
down in this mode.
