Note the following details of the code protection feature on Microchip devices:
• Microchip products meet the specification contained in their particular Microchip Data Sheet.
• Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
• There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
• Microchip is willing to work with the customer who is concerned about the integrity of their code.
• Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”

Chapter 2. Getting Started
2.1 EVB-USB5537 CONFIGURATION
The EVB-USB5537 provides different configuration options. It can be configured via
default internal register settings, downloadable external firmware to an on board SPI
Flash, through SMBus, or through the onboard configuration switches. When config-
ured with the default internal register settings, the device operates as a USB 3.0/2.0
hub with seven battery charge enabled USB ports and Microchip-SMSC’s standard
VID/PID/DID settings.
A block diagram of the EVB-USB5537 is shown in Figure 2-1.
FIGURE 2-1: BLOCK DIAGRAM
2.2 CONFIGURATION SOURCE – INTERNAL DEFAULT
When the USB5537B-60xx does not detect a valid SPI Flash image or SMBus config-
uration upon power-up, the EVB-USB5537 uses internal default register settings. It
also sets the Vendor ID, Product ID, Language ID, Device ID, and additional settings
from internal ROM code.

2.3 CONFIGURATION SOURCE – EXTERNAL SPI FLASH AND SMBUS
Upon power-up, the USB5537B-60xx first looks for an external SPI Flash device with
a valid Firmware image loaded. If one is found, the external ROM is enabled and code
execution is then initiated from the external SPI device. If a SPI Flash device is not
found, the USB5537B-60xx will operate from the internal ROM. After booting to internal
or external ROM, the firmware checks to see whether SMBus is enabled. The SMBus
can operate in either legacy mode (USB 2.0 only) or advanced mode (access to both
USB 2.0 and USB 3.0 registers). Note that the default configuration is for SMBus to
operate in advanced mode.
FIGURE 2-2: SPI DEVICE ENABLED (J13)
By default, the SPI Flash chip, U11 is populated. The 10 kOhm pull up resistors (R74
and R75) on the SPI device’s Write Protect (nWP) and Hold (nHOLD) pins must also
be populated in order to use external flash. The 10 kOhm pull-up resistor (R13) on the
SPI_SPD_SEL pin of the USB5537B-60xx must also be populated in order to select
60MHz SPI operation, as opposed to 30MHz operation. Additionally, the J13 SPI Flash
Enable header is shorted by default in order to enable the SPI device. If the user
wanted to disable the SPI device for any reason, the jumper from the J13 SPI Flash
Enable header would have to be removed. The external flash can be programmed using the
Microchip ProTouch MPT software tool which can be downloaded from the Microchip website at
http://www.Microchip.com/ProTouch.
SMBus data and clock can be controlled via the onboard SMBus header, J15. The
SMBus interface is disabled by default through the 100 kOhm pull-down resistor (R58)
on the SM_CLK pin of the USB5537B-60xx. In order to enable SMBus communication,
a valid SMBus host must be connected and SM_CLK must be pulled high through a 10
kOhm resistor. This can be achieved by shorting pins 1 and 2 on the J14 Manual
SMBus EN header. Alternatively, if an Aardvark tool is inserted into the J15 SMBus I/F
header, this tool will automatically pull SM_CLK high and then the J14 Manual SMBus
EN header does not need to be shorted (or installed). When SMBus is enabled, the
USB5537B-60xx configures the GPIOs to act as an SMBus slave. As an SMBus slave,
the USB5537B-60xx will wait indefinitely for the SMBus configuration. If no external
options are detected, the USB5537B-60xx will be configured from the internal default
registers.
Note: Refer to the Protouch MPT User Manual on using this software to program
the configuration.

2.4 POWER SOURCE – SELF-POWERED
The EVB-USB5537 supports only self-powered operation and is powered through one
+12.0V regulated external power supply. The +12.0V external DC power supply plugs
into the 2.5 mm connector, J11 on the board. Alternatively, an external voltage can be
injected onto the J10 Ext. 12V header, which is not populated by default. The +12.0V
feeds a 6A regulator which outputs +5.25 V across the board. This +5.25 V output is
the input to the +3.3 V and +1.25 V onboard regulators as shown in Figure 2-1.
2.5 DOWNSTREAM PORT POWER CONTROL
Each of the seven USB downstream port powers are controlled via a 2.5 A port power
device with an auto-discharge function (AP2511). The higher current capabilities of
these AP2511 devices allow for all seven downstream ports to support battery charging
up to a maximum of 5 A total at any one time.
The AP2511 devices connected to downstream ports 1 through 4 (U5 - U8) are enabled
via the PRT_CTL[4:1] pins on the USB5537B-60xx. Downstream ports 1 through 4 also
have individual overcurrent sensing available.
The AP2511 devices connected to downstream ports 5 through 7 (U10, U12 and U13)
have several options for how they can be controlled. By default, the AP2511 “Enable”
pins for these ports are pulled high through 10 kOhm resistors (R64, R73 and R76).
Additionally, these enable pins are connected to the PRT_CTL[7:5] pins on the
USB5537B-60xx. The PRT_CTL pins can either drive the enable pins of the port power
controllers high to enable or low to disable the port power controllers. Note that in order
for PRT_CTL5 to control the U13 port power controller, pins 1 and 2 of the J9 PPwr5
header must be shorted together.
FIGURE 2-3: PORT 5 POWER ENABLE (J9)
If the user wants to permanently enable these port power controllers for downstream
ports 5 through 7, the jumper on J9 can be removed and the 0 Ohm resistors R81 and
R69 can be removed. In this configuration, the AP2511 enable pins for these three
ports will be permanently pulled high through the 10 kOhm, pull-up resistors mentioned
above and therefore will always be turned on. They will no longer be controlled by the
USB5537B-60xx. Downstream ports 5 through 7 have their overcurrent sense signals
handled differently than from how ports 1 through 4 are handled. The OCS pins on the
AP2511 devices for these three ports are connected to the port power control signals
of the USB5537B-60xx. In order to view overcurrent sensing on downstream ports 5
through 7, first the PRT_CTL[7:5] pins must be tied to the enable pins of the AP2511
devices. Also, the 0 Ohm resistors R67, R72 and R86 must also be populated (which
they are by default). This allows over current sensing capabilities on these three down-
stream ports. Another option available for downstream ports 5 through 7 is to gang the
over current sense pins so that all OCS pins of the U10, U12 and U13 port power con-
EVB-USB5537 Evaluation Board User’s Guide
DS50002273A-page 18 2014 Microchip Technology Inc.
trollers are tied together. In this configuration, the 0 Ohm resistors R67, R72 and R86
would then have to be removed and instead the 0 Ohm resistors R66, R71 and R82
would be installed. When these three resistors are populated, OCS for ports 5 through
7 are all tied together and are monitored on the OCS4 pin of the USB5537B-60xx. This
is not the default configuration.
Before applying power to the EVB-USB5537, the first four USB 3.0 downstream ports
must be properly configured through the onboard switches. All four downstream ports
can be configured in a variety of ways described below. All of the OCS pins as well as
the PRTCTL pins have configuration options available through these configuration
switches. After the board has been powered, changing the position of these switches
will not affect the current configuration. Any changes to the switches will require the
EVB-USB5537 to have its power recycled or RESETn asserted before the changes can
take affect. The sections below describe the different configuration options available for
these USB5537B-60xx strap pins.
FIGURE 2-4: INITIAL CONFIGURATION
OCS Strap Options: Non-Removable Select
The OCS[4:1] pins of the USB5537B-60xx have strap options that are selectable
through a 2-Position Double Pole Double Throw (DPDT) switch which are labeled
“Non_Rem Cfg”. The OCS1 pin is associated with downstream Port 1 and is tied to
SW2. When SW2 is in the default position, pins 1 and 2 are shorted together as well as
pins 4 and 5 on the switch. This switch position pulls the OCS1 pin high to +3.3 V
through a 10 kOhm resistor which configures downstream port 1 to be in the “Remov-
able” state and its associated dual LED (D5) will be turned on green. To change this
configuration, SW2 should be switched to the opposite position which will short pins 2
and 3 together as well as pins 5 and 6 on the switch. Once the switch position has been
changed, power must be recycled on the EVB-USB5537. This switch position pulls the
OCS1 pin low to ground through a 1 kOhm resistor which configures downstream port
1 to be in the “Non-Removable” state and the dual LED (D5) will now be turned on yel-
low.
This same selection process can be made to the OCS pins and switches that are tied
to the downstream ports 2 through 4. The table below describes the different OCS strap
options available for each of the first four OCS pins on the USB5537B-60xx.

FIGURE 2-6: NON-REMOVABLE STATE
Port Power Strap Options: Battery Charge Enable and Port Disable Select
The PRTCTL[4:1] pins of the USB5537B-60xx also have strap options that are select-
able through a 3-Position Double Pole Double Throw (DPDT) switch which are labeled
“Port Pwr Cfg”. The PRT_CTL1 pin is associated with downstream Port 1 and is tied to
SW1. When SW1 is in the default position, pins 1 and 2 are shorted together as well as
pins 4 and 5 on the switch. This switch position pulls the PRT_CTL1 pin high to +3.3 V
through a 10 kOhm resistor which configures downstream port 1 to be in the “Battery
Charge Enabled” state and its associated LED (D10) will be turned on green. Alterna-
tively SW1 can be positioned all the way down to the “Port Dis” position. This switch

position pulls the PRT_CTL1 pin low to ground through a 1 kOhm resistor which con-
figures downstream port 1 to be disabled and therefore no power will be applied to
VBUS on this downstream port. Also the “Port 1 Disable” LED (D9) will turn on red. If
SW1 is switched into the middle OFF position, labeled as “Prt En, BC Dis” on the
EVB-USB5537, the port power controller on downstream port 1 will act as a standard
non-battery charging Port Power Controller (PPC). Note again that any time the switch
position has been changed, power must be recycled on the EVB-USB5537.
This same selection process can be made to the PRTCTL pins and switches that are
tied to downstream ports 2 through 4. Note that in either configuration mode, as long
as the switch is not in the OFF position, the downstream port power LEDs (D1-D4) will
light up green whenever power is being applied to VBUS on the associated down-
stream port. Additionally, whenever power is being applied to VBUS on downstream
ports 5 through 7 (which do not have switchable strap options available), the down-
stream port power LEDs (D20-D22) will also light up green. When the “Port Pwr Cfg”
switch is switched into the middle OFF position, the associated downstream port power
LED will be turned off which shows that no power is applied to that particular down-
stream port. The table below describes the different PRTCTL strap options available
for each of the first four PRTCTL pins on the USB5537B-60xx.

Dynamic Battery Charge Select
The final switch to consider when configuring the USB5537B-60xx is the “Dynamic BC
Select” switch, SW10. Once each of the first four downstream ports have been config-
ured in one of the options described above, the Dynamic Battery Charge Select switch
can then be configured to either turn battery charging on for all BC Enabled ports, or
turn battery charging off. To enable battery charging on all BC Enabled downstream
ports, SW10 must be in the “Enable” position which shorts pins 1 and 2 and also pins
4 and 5 together on the switch (this is the default position). When battery charging is
enabled, the DYNCPDISn (active low) pin on the USB5537B-60xx is pulled high to +3.3
V through two 4.7 kOhm resistors in series and the associated dual LED (D19) will turn
on green. To disable battery charging on all downstream ports, SW10 must be in the
“Disable” position which shorts pins 2 and 3 and also pins 5 and 6 together on the
switch. When battery charging is disabled, the DYNCPDISn pin on the
USB5537B-60xx is pulled low to ground through two 4.7 kOhm resistors in series and
the associated dual LED (D19) will turn on red. An optional 2-pin Ext. DYNBC header
is provided as well (J12) so that the user can inject a signal onto the DYNCPDISn pin
through an external source.
