OSD335x

A New Era of Integration and Flexibility

 Faster and Smaller Designs, Simplified Supply Chain, Lower Cost Manufacturing

The Octavo Systems OSD335x System-in-Package (SiP) device is the first device in the OSD335x Family.  It integrates the Texas Instruments Sitara ARM® Cortex®-A8 AM335x Processor, DDR3 memory, TPS65217C PMIC, TL5209 LDO, and all needed passive components into a single 27mm X 27mm BGA package.

Integrating the DDR3, power system, and passive devices into the single package removes the complexities of DDR3 to processor interfacing and power sequencing.  This allows for a vastly simplified final system design.

The 400 Ball BGA package is 40% smaller than the equivalent discrete design making it a great solution for space constrained applications.  The package also utilizes a 1.27mm (50 mil) ball pitch making it extremely easy to assemble.  The ball pitch also allows for the use of more relaxed Printed Circuit Board (PCB) design rules, saving PCB cost.

The OSD335x is the quickest and easiest way to implement a system around the TI AM335x while also providing space savings, simplified supply chains, lower cost manufacturing, and greater reliability.

BeagleBone Black Wireless Featuring the OSD335xThe BeagleBone™ Black Wireless is one of the quickest ways to get up and running with the OSD3358.  This low cost board from BeagleBoard.org features the OSD3358-512M-BAS as well as 802.11 b/g/n and Bluetooth v4.1.  It is also compatible with all BeagleBone™ Black expansion capes.  The BeagleBone™ Black Wireless is completely open-source and is supported by the large and active BeagleBoard.org® community.

 

 

GHI BeagleBoard OSD3358 Development BoardGHI Electronics, our lead design partner, has created a development board for getting started with the OSD335x Family.  It includes the OSD3358-512M-BAS devices as well as numerous peripherals, interfaces, and a capacitive touch screen making it an ideal starting point for any project. The system can be powered through USB or by connecting a power pack.

This board is BeagleBone Compatible, meaning it will run the BeagleBone linux distributions found on BeagleBoard.org

ghi-th-board_300pxThe OSD3358 TH Module from GHI Electronics makes it extremely easy to start using the OSD335x in your own system.  It has everything you need to quickly boot Linux and gives you easy access to all of the IO that you would need for your own design.  This is a minimalist board and perfect if you are looking to prototype with the OSD335x in your system.

This board is BeagleBone Compatible, meaning it will run the BeagleBone linux distributions found on BeagleBoard.org

Reference Designs

OSD3358 SBC Reference Design
OSD3358 SBC Reference Design

In order to help get you started using the OSD335x we, in partnership with BeagleBoard.org, have created a reference design around the OSD3358-512M-BAS.  The reference design is a Single Board Computer that is compatible with BeagleBone Black ecosystem.  This reference design will run the BeagleBone Linux distributions and is also compatible with all capes.  If created exactly it will perform like a BeagleBone Black.  This is a reference design only.  The boards are not available to purchase.

Note:  This is reference design replaced the original OSD3358 SBC Reference Design that was done in Orcad.  This design represents the current best practices for designing with the OSD335x.  If you are interested in the legacy design it can be found here.

FAQs

We plan to support this device as long as TI continues to support the AM335x device. In fact, we will most likely be able to support it longer than TI will.

One is broken into 20 sub blocks with each block showing one of the 20 columns of the OSD335x. The other is broken into 12 sub blocks, each grouping signals according to functionalities that the OSD335x provides. So, you can use which ever one fits your needs. Both are linked below.

These power pins are driven by the TPS65217C PMIC and are used internally to power the AM335x, DDR and other components.  These pins are all connected within the SiP and do not be connected externally.  Optionally, these pins can be brought out as test points for debugging purposes only.  They should NEVER be used to power external components.

The OSD335x supports all the frequencies supported by corresponding AM335x present inside. For example, the AM3358 inside the OSD3358 supports 6 Operational Performance Points(OPP). It can run at 300MHz, 600MHz, 720MHz, 800Mhz and 1GHz. These operational performance points are set using the Digital Phase Locked Loops(DPLLs) and MPU, CORE voltages on the AM335x. The following figure from the AM335x datasheet (Table 5-7) shows the OPPs, the corresponding MPU voltage to be set and the frequency of operation of the OPP (Source: AM335x datasheet).

The OSD335x is BeagleBoard Compatible meaning it can run any of the software provided by BeagleBoard.org. Here is a link to getting started on Beaglebone.

TI also provides Linux and TI-RTOS support for software development. Here is a link to their resources.

Yes, OSD335x runs all Linux distributions supported by TI for AM335x. It is also officially BeagleBoard Compatible so it will run the Linux distributions found on Beaglebone Black.

Pin map of OSD335x corresponds to the pin map of the ZCZ package of the AM335x.

The ball map of the OSD335x was designed to match the ball map of AM335x ZCZ package except for a few changes. The following figure highlights the changes that were made to AM335x ZCZ ball map.

Violet and Grey pins are the only pins that have been moved or functionally changed.

Blue pins (AM335x DDR interface) should be left unconnected.

Green pins (AM335x Power input pins) should be left unconnected or brought out as test points for monitoring.

Orange pins are additional pins added to the package for more functions.

Please refer to the datasheet for their functional description.

The major changes in functionality are listed below. (more…)
