4.2 POWER SOURCES
Supply Voltage
IGEP™ COM AQUILA AM335x module cannot be used as stand-alone module, so keep in mind that expansion
board must power VIN signal input, this signal is defined into SODIMM-200 interface (from pin 1 to 4). VIN
signal can vary from 3,8V to 5,5V DC, for more information see electrical characteristics table in Chapter 7.
Output Voltage and ADC Voltage reference
IGEP™ COM AQUILA AM335x module has a linear regulator that provides an output voltage 3,3 V @ 1 A
(VOUT), VOUT signal is defined into SODIMM-200 interface from pin 5 to 7 and 9 to 12. If expansion board uses
VOUT power supply, Hardware designer should take care to calculate VIN max current consumption.

There is also available an output power reference supply (VREFP_ADC) of 1,8 V, defined into SODIMM-200
interface pin 184.It’s used to fix the reference positive voltage for analog-to-digital converters (ADC).
RTC Battery
The RTC_BATTERY signal (SODIMM-200 interface pin 13) allows to maintain RTC peripheral from IGEP™ COM
AQUILA AM335x module when it is not power supplied (VIN). An example can be found into figure 8.

GND Pins
Digital Ground
All the digital GND pins are internally connected together, so it’s not need to connect all of them. However, the
user has to considerer how many of them connect according the total consumption of the complete circuit (the
IGEPTM COM Aquila AM335x and the base board developed). At the same time, to make the routing of buses
easier, the ground connection chosen will be the nearest to the function used.
There have to be a minimum of 4 GND pins connected, distributed in the most possible equal way along the
SODIMM-200 connector (to get an equalized ground).
Analog Ground
AGND_ADC (SODIMM-200 interface pin 183) is a dedicated ground for IGEP™ COM AQUILA AM335x module
analog converters. It improves analog captures avoiding the noise introduced by the logic ground when both
grounds are detached.
GND Earth
Hardware designer must take care of GND Earth.
In the figure 9 is an example about how to connect these grounds. The digital and analog grounds are separated
by an EMI filter. By the other way, in order to enable GND Earth, R100 resistor must be unmounted and connect
J991 to GND Earth source.

4.3 CONTROL SIGNALS
There are different pins used as general control signals. They affect: Boot Mode, management of the power
supply, resets and wake up the system from a state of suspension.
Boot Mode
The Boot mode functionality (SODIMM-200 interface pin 8) is equivalent to #SYS_BOOT4 (SYS_BOOT4
inverted) signal. When IGEP™ COM AQUILA AM335x module is powered on, it reads this pin and it boots from
NAND/MMC0 or MMC0 in function of its status, the following table shows the complete sequence.
Pin #8
Boot Mode
NC
Sequence: UART0 SPI0 XIP MMC0
DGNG
Sequence: NAND NANDI2C MMC0 UART0
Table 5 Boot Mode pin
#SYS_BOOT4 pin uses LCD_DATA4 signal (SODIMM-200 interface pin 141) to control sysboot mode.
Hardware designer can use independently LCD_DATA4 and #SYS_BOOT4 signals because there are isolated.
It’s recommended to use a jumper header or a switch in series with a low resistor value (as a short circuit
protector element) tied to GND into expansion board.

Reset pins
There are three different Reset-IOs: #PWR_KILL (SODIMM-200 interface pin 14), PORZ (SODIMM-200
interface pin 16) and WarmResetn (SODIMM-200 interface pin 17):
If #PwrKill is driven to Low state (default timeout 8 seconds), power supplies from PMIC will be turned off until
#PwrKill is set High. The following diagram shows #PwrKill distribution.
If PORz is driven to Low state (at least 154 microseconds), Power-On-Reset (PORz) will be active and will reset
the complete processor and all the logic that uses asynchronous reset. The following diagram shows PORz
distribution.

If WarmResetn is driven to Low state (at least 90 nanoseconds), Warm Reset is active and reset partially the
processor: the SYSBOOT pins are not latched, PLLs are not affected and most debug subsystem logic is not
affected (this allows to maintain any debug session throughout a warm reset event). As an input, it’s typically
used by an external source as a device reset and as an output, it can be used to reset external devices. The
following diagram shows WarmResetn distribution.
Moreover, there is a generic output reset signal (SODIMM-200 interface pin 15) controlled through of GPIO3_8.
This reset doesn't affect to processor and it is intended to use for external peripherals. The following diagram
shows #RESET_OUT distribution.
