Preface

This phyBOARD-WEGA-AM335x Board Hardware Manual describes the System on Module's design and functions. Precise specifications for the TI AM335x processor can be found in the processor datasheet and/or user’s manual.

In this hardware manual and in the schematics, active low signals are denoted by a "/" preceding the signal name, for example: /RD. A "0" represents logic-zero or low-level signal, while a "1" represents a logic one or high-level signal.

Declaration of Electro Magnetic Conformity of the phyBOARD-WEGA-AM335x

PHYTEC System on Modules (SOMs) are designed for installation in electrical appliances or, combined with the PHYTEC Carrier Board, can be used as dedicated Evaluation Boards (for use as a test and prototype platform for hardware/software development) in laboratory environments.

CAUTION:

PHYTEC products lacking protective enclosures are subject to damage by ESD and, hence, may only be unpacked, handled or operated in environments in which sufficient precautionary measures have been taken in respect to ESD-dangers. It is also necessary that only appropriately trained personnel (such as electricians, technicians and engineers) handle and/or operate these products. Moreover, PHYTEC products should not be operated without protection circuitry if connections to the product's pin header rows are longer than 3 mm.

PHYTEC products fulfil the norms of the European Union's Directive for Electro Magnetic Conformity only in accordance to the descriptions and rules of usage indicated in this hardware manual (particularly in respect to the pin header row connectors, power connector and serial interface to a host-PC).

Implementation of PHYTEC products into target devices, as well as user modifications and extensions of PHYTEC products, is subject to renewed establishment of conformity to, and certification of, Electro Magnetic Directives.

Users should ensure conformance following any modifications to the products as well as implementation of the products into target systems.

The phyBOARD-WEGA-AM335x Board is one of a series of PHYTEC System on Modules that can be populated with different controllers and, hence, offers various functions and configurations. PHYTEC supports a variety of 8/16 and 32-bit controllers in two ways:

1. As the basis for Rapid Development Kits which serve as a reference and Evaluation platform.

2. As insert-ready, fully functional phyCORE OEM modules, which can be

Embedded directly into the user's peripheral hardware design.

© PHYTEC Embedded Pvt. Ltd. 2014 7

Implementation of an OEM-able SOM subassembly as the "core" of your embedded design allows you to focus on hardware peripherals and firmware without expending resources to "re-invent" microcontroller circuitry. Furthermore, much of the value of the phyCORE module lies in its layout and test.

“Production-ready Board Support Packages (BSPs)” and Design Services for our hardware further reduce development time and expenses. Take advantage of PHYTEC products to shorten time-tomarket, reduce development costs, and avoid substantial design issues and risks.

For more information refer to: http://www.phytec.in/services/hardware.html

1. Introduction

1.1 Hardware Overview:

The WEGA Board for phyCORE-AM335x is a low-cost, feature-rich software development platform supporting the TI AM335x processor families. At the core of the phyBOARD-WEGA-AM335x is the

PCL-051/phyCORE-AM335x System On Module (SOM) in a direct solder form factor, containing the

AM335x processor, SDRAM, NAND Flash, power regulation, supervision, transceivers and other core functions required to support the phyBOARD-WEGA-AM335x. Surrounding the SOM is the PBA-CD-

02/ phyBOARD-WEGA-AM335x Carrier, adding power input, buttons, connectors, signal breakout amongst other features.

The PCL-051 System On Module is a connector-less, BGA style variant of the PCM-051/phyCORE-

AM335x SOM. Unlike traditional PHYTEC SOM products that support high density connectors, the

PCL-051 SOM is directly soldered down to its Carrier Board using PHYTEC's Direct Solder Connect technology. This solution offers an ultra-low cost Single Board Computer for the AM335x processor, while maintaining most of the advantages of the SOM concept.

Adding the phyCORE-AM335x SOM into your own design is as simple as ordering the connectored version (PCM-051) and making use of our phyBOARD-WEGA-AM335x Carrier Board (PBA-CD-02), or RDK Carrier Board (PCM-953) reference schematics. A summary of the phyBOARD-WEGA-

AM335x features, along with a block diagram are presented below.

2. PCL-051/phyCORE-AM335x System on Module

This chapter gives a brief introduction to the PCL-051/phyCORE-AM335x System on Module

(SOM), highlighting its benefits and features. For more detailed information, please refer to the

Hardware Manual for the modular, connectored version of the SOM (PCM-051) by clicking here .

The phyCORE-AM335x belongs to PHYTEC’s phyCORE System on Module (SOM) family. The phyCORE SOMs represent the continuous development of PHYTEC SOM technology. Like its mini-, micro-, and nano MODULE predecessors, the phyCORE boards integrate all core elements of a microcontroller system on a sub miniature board and are designed in a manner that ensures their easy expansion and embedding in peripheral hardware developments.

As independent research indicates that approximately 70% of all EMI (Electro Magnetic

Interference) problems stem from insufficient supply voltage grounding of electronic components in high frequency environments, the phyCORE board design features an increased pin package. The increased pin package allows dedication of approximately 20% of all connector pins on the phyCORE boards to ground. This improves EMI and EMC characteristics and makes it easier to design complex applications meeting EMI and EMC guidelines using phyCORE boards even in high noise environments. phyCORE boards achieve their small size through modern SMD technology and multi-layer design.

In accordance with the complexity of the module, 0402-packaged SMD components and laser-drilled

Microwave are used on the boards, providing phyCORE users with access to this cutting edge miniaturization technology for integration into their own design.

The PCM-051, connector version of the phyCORE-AM335x is a sub-miniature (44 mm x 50 mm) insert-ready SOM populated with AM335x processor. Its universal design enables its insertion into a wide range of embedded applications. All processor signals and ports extend from the processor to highdensity pitch (0.5 mm) connectors aligning two sides of the board. This allows the SOM to be plugged like a "big chip" into a target application.

The PCL-051, connector less version of the phyCORE-AM335x populating the phyBOARD-

WEGA-AM335x is identical to the connectored version, with the exception of the connection interface.

Instead of two high density connectors aligning the edges of the board, the PCL-051 solders directly down to its Carrier Board with a BGA style footprint.

Precise specifications for the processor populating the board can be found in the applicable processor user's manual and datasheet. The descriptions in this manual are based on the AM335x processor. No description of compatible processor derivative functions is included; as such functions are not relevant for the basic functioning of the WEGA Board.

5.6 USB Connectivity (X15 and X42)

The phyBOARD-Wega provides one USB Host and one USB OTG interface.

USB0 is accessible at connector X42 (USB Micro-AB) located at the back side of the phyBOARD-

Wega. It is configured as USB OTG. USB OTG devices are capable to initiate a session, control the connection and exchange host and peripheral roles between each other. This interface is compliant with USB revision 2.0.

USB1 is accessible on the top at connector X15 (USB Standard-A) and is configured as USB Host.

Components supporting the USB Interfaces

LED D8 displays the status of USB0_VBUS and LED D7 the status of USB1_VBUS. For later expansion boards the USB1 interface can be routed to the expansion connector (X69) by populating

J72 and J73 (2+3).

5.7 Audio Interface (X55 andX73)

The audio interface provides a method of exploring AM335x’s audio capabilities. The phyBOARD-

Wega is populated with an audio codec at U35. The audio codec is connected to the AM335x’s

McASP0 interface to support stereo line input and stereo line output at connector X73. In addition to that the phyBOARD-Wega has one direct mono speaker output (2 × 1 W) at the Molex connector X55.
