Conventions, Abbreviations and Acronyms
This hardware manual describes the PB-01802-xxx Single Board Computer (SBC), hereby
referred to as phyBOARD-Regor AM335x. The manual specifies the
phyBOARD-Regor AM335x's design and function. Precise specifications for the Texas
Instruments AM335x microcontrollers can be found in the Texas Instrument’s
Sheet and Technical Reference Manual
.
Conventions
The conventions used in this manual are as follows:
Signals that are preceded by an "n", "/", or “#”character (e.g.: nRD, /RD, or #RD), or
that have a dash on top of the signal name (e.g.: RD) are designated as active low
signals. That is, their active state is when they are driven low, or are driving low.
A "0" indicates a logic zero or low-level signal, while a "1" represents a logic one or
high-level signal.
2
The hex-numbers given for addresses of I
C devices always represent the 7 MSB of the
address byte. The correct value of the LSB, which depends on the desired command
(read (1), or write (0)), must be added to get the complete address byte. E.g. the given
address in this manual 0x41 => the complete address byte = 0x83 to read from the
device and 0x82 to write to the device.

Preface
Preface
As a member of PHYTEC's new phyBOARD® product family, the phyBOARD-Regor AM335x is
one of a series of PHYTEC System on Modules (SBCs) that offer off-the-shelf solutions for a
huge variety of industrial applications. The new phyBOARD
series of extremely compact embedded control engines featuring various processing
performance classes. All phyBOARDs are rated for industry, cost optimized, and offer longterm availability. The phyBOARD-Regor AM335x is one of currently six industrial-grade
carrier boards which are suitable for series production and that have been realized in
accordance with PHYTEC's new SBCplus concept. It is an excellent example of this concept.
For easy implementation into industrial control system racks, the
phyBOARD-Regor AM335x comes in a housing with integrated DIN-Rail sockets.
Furthermore, the board is equipped with connectors allowing for interconnection to
commonly used industrial interfaces.
SBCplus Concept
The SBCplus concept was developed to meet many slight differences in customer
requirements with little development effort and thus greatly reduce the time-to-market.
The core of the SBCplus concept is the SBC design library (a kind of construction set) that
consists of a great number of function blocks (so-called "building blocks") which are
constantly refined. The recombination of these function blocks allows PHYTEC to develop a
customer specific SBC within a short time. Thus, PHYTEC is able to deliver production-ready
custom Single Board Computers within a few weeks at very low costs.
The already developed SBCs, such as the phyBOARD-Regor, each represent an intersection
of different customer wishes. Because of this, all necessary interfaces are already available
on the standard versions. This allows the user to integrate the phyBOARD in a large number
of applications without modification. For any necessary detail adjustments, extension
connectors are available to enable adding a wide variety of functions.
Customized Expandability from PHYTEC
Common interface signals route to standard connector interfaces on the carrier board such
as Ethernet, CAN, RS-232, and audio. Due to the easily modifiable phyBOARD design
approach (see "
SBCplus concept
"), these plug-and-play interfaces can be readily adapted
into customer-specific variants according to end system requirements.

Implementation of an OEM-able SBC subassembly as the "core" of an embedded design
allows for increased focus on hardware peripherals and firmware without expending
resources to "re-invent" microcontroller circuitry. Furthermore, much of the value of the

SBC lies in its layout and test.

Figure 6: Power Supply Connector X1
The phyBOARD-Regor is equipped with a 5-pole Phoenix Contact MINI COMBICON base strip
3.5 mm connector (X1) suitable for a single 24 V ±10 % supply voltage.
The required current load capacity depends on the specific configuration of the phyCORE
mounted on the phyBOARD-Regor, the particular interfaces enabled while executing
software, as well as whether an optional expansion board is connected to the carrier
board.
The permissible input voltage is +24 V DC ±10 % at the 5-pole Phoenix Contact MINI
COMBICON base strip X1 or, alternatively, at the CARD Edge connector X7 (
section 2.2.8
). A
24 V adapter with a minimum supply of 1A is recommended to supply the board.

The Controller Area Network (CAN) bus offers a low-bandwidth, prioritized message
fieldbus for serial communication between microcontrollers. It efficiently supports
distributed real time control with a high level of security. The DCAN module of the AM335x
implements the CAN protocol according to the CAN 2.0B protocol specification and
supports bit rates up to 1 Mbit/s. The CAN interface of the phyBOARD-Regor AM335x is
connected to the CAN-controller DCAN1 of the AM335x SOM.

The Ethernet interfaces of the phyBOARD-Regor are accessible at dual RJ45 connectors X9A

Both Ethernet interfaces are configured as 10/100Base-T networks. The LEDs for LINK
(green) and SPEED (yellow) indication are integrated in the connector. Both Ethernet
transceivers support HP Auto-MDIX, eliminating the need for a direct connect LAN or a
cross-over path cable. They detect the TX and RX pins of the connected device and
automatically configure the PHY TX and RX pins accordingly.
2.2.4.1 MAC Address
In a computer network such as a local area network (LAN), the MAC (Media Access Control)
address is a unique computer hardware number. For a connection to the Internet, a table is
used to convert the assigned IP number to the hardware’s MAC address.
In order to guarantee that the MAC address is unique, all addresses are managed in a
central location. The MAC address of the phyBOARD-Regor is saved on the CPU (AM335x).

Figure 13: MMC/SD Card Interface at Connector X11
The phyBOARD-Regor provides a standard microSDHC card slot at X11 for connection to
MMC/SD interface cards. It allows for an easy and convenient connection to peripheral
devices like SD and MMC cards. Power to the SD interface is supplied by inserting the
appropriate card into the MMC/SD connector which features card detection, a lock
mechanism and a smooth extraction function by Push-in/ Push-out of card.
Ensure that the device is not unplugged while it is still mounted. This may
result in data loss!
DIP switch S4 allows the device to toggle between booting from NAND or SD card. In order
to boot from an SD card, S4 must be switched ON (refer to

Figure 14: Digital GPIOs at Connector X2
The phyBOARD-Regor provides four digital IOs that are designed for processing DC-signals
with up to 24 V DC. The digital output voltage depends on the input voltage of the board.
Input and output signals are routed to the CPU (AM335x) through two discrete
optocouplers for galvanic isolation. Thus, it is possible to write and read the status of every
single GPIO of the phyBOARD-Regor simultaneously.
board. In case the GPIOs are used as outputs, the current is self-limited by
the output-optocoupler and should not exceed 750mA for each GPIO
channel. These outputs are low-side outputs.
When the GPIOs on the phyBOARD-Regor are used as digital inputs, they are configured
active high with the following switching voltages:

Table 17: Power ratings of the phyBOARD-Regor
4.2 Product Temperature Grades
It is mandatory to determine if the use case suites the temperature range
of the chosen module (see below). If necessary, a heat spreader can be
The feasible operating temperature of the SOM greatly depends on the use case of your
software application. Modern high performance microcontrollers and other active parts
like the ones described within this manual are usually rated by qualifications based on
tolerable junction or case temperatures. Therefore, making a general statement about
minimum or maximum ambient temperature ratings for the described SOM is not possible.
However, the above mentioned parts are available in different temperature qualification
levels by the producers. PHYTEC offers SOMs in different configurations, making use of
those temperature qualifications. To indicate which level of temperature qualification is
used for active and passive parts of a SOM configuration, PHYTEC has categorized SOMs in
three temperature grades.
These grades describe a set of components which, in combination, add up to a useful set of
product options with different temperature grades. This enables PHYTEC to make use of
cost optimizations depending on the required temperature range.
In order to determine the right temperature grade and whether the minimum or maximum
qualification levels are met within an application, the following conditions must be
defined when considering the use case:
Table 18
describes these grades in detail.
