PHYTEC Pin-Compatible phyCORE SoMs And phyBOARD-Segin Single-Board Computer

PHYTEC’s phyCORE System-on-Modules (SoMs) present a low-cost, low-energy-consumption solution for high-power embedded Linux in a compact footprint of just 36 x 36 mm. These single-sided castellated boards can be directly soldered into larger systems for reduced manufacturing cost and faster time to market, with PHYTEC providing ample support via FAEs, baseboard schematics, and long-term availability, with constant product change notifications from chip suppliers and alternative arrangements in the event of component changes. Applications for these SoMs are vast but include medical, industrial, off-vehicle automotive, consumer, point-of-sale, IoT, and more.

The phyCORE range of SoMs has many models, and the three discussed in this board form offer pin-compatibility for easy swapping in new or old systems. All feature phyBSP (PHYTEC Board Support Package) for extensive support, security, OS updates and device management through the Yocto Project, as well as embedded hardware and software security.


The phyCORE-STM32MP13x SoM is built around STMicroelectronics’ STM32MP13x processor, which features a 32-bit Arm Cortex-A7 core running at up to 1 GHz. In addition to this, an Arm NEON SIMD extension accelerates multimedia and signal processing algorithms, and advanced hardware security and encryption features protect your device from external attacks – these include Arm TrustZone, a true random number generator, CRC calculation, tamper, temperature/voltage/frequency monitoring, and more.

The SoM is 3.3- and 5-V tolerant for flexible integration with other systems, and extended low-power modes are particularly useful for IoT applications running a full Linux system. External memory includes up to 256 GB eMMC or 2 GB NAND flash, up to 1 GB DDR3L, and up to 32 kB EEPROM. The SoM features the standard set of communication interfaces in addition to Gbit ethernet, a 24-bit full-HD display interface (30 fps), and audio and camera interfaces.

phyCORE-i.MX 91/93

The phyCORE-i.MX 91/93 SoMs provide two options based on NXPs i.MX 91 or i.MX 93 devices, offering a more powerful solution than the phyCORE-STM32MP13x. The i.MX 91 features a single Arm Cortex-A55 core running at up to 1.5 GHz, and the i.MX 93 adds to this with two Arm Cortex-A55 cores running at up to 1.7 GHz and a real-time Arm Cortex-M33 MCU supported by an Arm Ethos-U65 microNPU for advanced AI/ML workloads at up to 2.3 TOPS, at significantly lower power consumption when compared to older processing architectures.

These SoMs feature similar levels of hardware security and interfaces to the phyCORE-STM32MP13x with the phyCORE-i.MX 93 offering a MIPI CSI-2 (1080p60) camera interface.

phyCORE-i.MX 6UL / ULL

The phyCORE-i.MX 6UL / ULL SoM presents the most cut down of these three pin-compatible Linux solutions with a single Arm Cortex-A7 running at up to 900 MHz. This enables the most cost-effective of the pin-compatible phyCOREs at just 20 euros per unit at 10,000 pieces, opening up the possibility of Linux to traditionally MCU-based systems. This saving comes with the loss of the full-HD display interfaceGbit ethernet, and ADCs at only 10-bit resolution, in contrast to the 12-bit resolution offered by the other phyCORE SoMs.

The phyBOARD-Segin Single-Board Computer (SBC) is typically based on the phyCORE-i.MX 6UL / ULL SoM, but the pin-compatibility means that it should be able to test all the options above for easy access to interfaces, including ethernet, camera (phyCAM-P), CAN, GPIOs, audio, touch, and more.
