Inside the OSD32MP1: A Closer Look at Octavo’s STM32MP1-Based SiP
In the world of embedded systems, performance, scalability, and simplicity often feel like trade-offs. But what if you didn’t have to choose? Octavo Systems’ OSD32MP1 System-in-Package is a compelling example of how thoughtful integration can empower developers with more of everything—power, efficiency, and flexibility—all in one tiny module. While reducing the size by 60%.
Let’s take a deeper look at what makes this SiP solution so powerful, and why engineers across industries are adopting it for their next generation of products.
What Is the OSD32MP1?
The OSD32MP1 is a System-in-Package (SiP) built around the STM32MP1 processor from STMicroelectronics. But it’s much more than just a processor. It includes:
- STM32MP1 microprocessor (Dual Arm® Cortex®-A7 + Cortex-M4)
- Up to 1GB of DDR3 memory
- Power Management IC (PMIC)
- Over 100 passive components
- High-density BGA package
All of that is packed into a footprint of just 18mm x 18mm—smaller than a U.S. penny.
Key Features and Capabilities
Here’s what makes the OSD32MP1 stand out in real-world designs:
- Dual-core Cortex-A7 + Cortex-M4: Ideal for running Linux on the A7 cores and real-time tasks on the M4 simultaneously.
- Integrated memory & power: No need to manage DDR layout or PMIC power rails—Octavo handles it.
- Flexible I/O: Gain full access to nearly every I/O available on the STM32MP1—no compromises. The OSD32MP1 supports a wide range of peripherals including CAN, SPI, I2C, UART, USB, Ethernet, and more, giving developers maximum flexibility for custom designs.
- Scalable design: Available with different memory sizes and pin-compatible upgrades.
Let’s face it—embedded Linux systems are powerful but notoriously complex to design from scratch. You have to worry about DDR layout, power sequencing, and countless support components. The OSD32MP1 removes most of those barriers.
Here’s how it helps developers:
- Simplifies PCB Design: You can design a fully functional Linux board using just two PCB layers with low-cost design rules—unheard of in traditional layouts.
- Accelerates Prototyping and Time to Market: With pre-integrated memory and power, your design is up and running in weeks instead of months.
- Reduces BOM Complexity and Obsolescence: Fewer components = fewer things to buy, solder, test, and debug. Obsolescence becomes a minimal factor considering hundreds of small parts are sourced, debugged, and assembled for you in a single package.
- Improves Reliability: By shifting from traditional PCB design to working directly with silicon die and semiconductor manufacturing processes, the OSD32MP1 significantly reduces potential points of failure. This results in a more robust and reliable system compared to discrete designs. For a deeper dive into the reliability advantages of SiP technology, check out Masood’s reliability application note »
- Reduces Size: By combining over 100 components into a small SiP device, hardware developers have 60% more space to work with.
Applications in the Field
The OSD32MP1 has been used in:
- Industrial gateways and controllers
- Wearables and smart sensors
- Medical imaging and diagnostic equipment
- Consumer electronics and AR headsets
- Robotics and automation systems
Its blend of Linux flexibility, real-time processing, and compact size makes it ideal for space- and power-constrained applications.
Developer-Friendly Tools
Octavo doesn’t just drop the hardware in your lap and wish you luck—they provide a full ecosystem:
- Reference designs and schematics
- Development boards (like the OSD32MP1-BRK)
- Yocto and OpenSTLinux support
- Community support and documentation
Whether you’re a hardware engineer or a Linux developer, you’ll find their resources incredibly helpful.
A Small Package with Huge Potential
The OSD32MP1 isn’t just about saving board space—it’s about making embedded Linux accessible to more developers. By handling the hardest parts of hardware design, Octavo Systems gives you the freedom to focus on what really matters: building a great product.
If you’re looking for a faster, easier, and more reliable way to deploy embedded Linux in your next project, the OSD32MP1 deserves a serious look.
