qdSOM STM32MP13x: an embedded system-on-module for industry and IoT

The qdSOM as a versatile embedded solution

System-on-module technology has become indispensable in modern embedded development. Wherever compact dimensions, modular architectures and substantial computing power are called for, it is used: in industrial automation, medical technology, transport, communications, consumer electronics and connected IoT devices.

The qdSOM STM32MP13x from querdenker engineering was developed for these fields: an energy-efficient, industrial-grade system-on-module with a wide range of interfaces and a lifecycle concept.

Technical highlights of the qdSOM STM32MP13x

The qdSOM is built on the STM32MP13x processor from STMicroelectronics.

General characteristics:

• compact dimensions: 29 x 29 x 3 mm
• direct solder connect: reliable and economical integration
• temperature range: -40 °C to +85 °C, in operation and in storage
• typical power consumption: 1.0 W
• weight: 6.2 g
• supply voltage: 5 V DC

• DDR3 DRAM: 512 MB (alternatives: 128 / 256 / 1024 MB)
• eMMC flash: 4 GB (alternatives: 8 / 16 GB)
• EEPROM: 2 kbit (alternatives: 4 / 8 kbit)

Processor and security functions:

• CPU: 1x ARM Cortex-A7, 650 MHz to 1 GHz

• further: 5x SPI, 5x I²C, 4x USART, 2x FDCAN, 1x TTCAN, 135 GPIOs, PWM, ADC, RTC, JTAG

Note: because of multiplexing, not all interfaces can be used at the same time. The actual number depends on the design.

Where it fits, and what it offers

The qdSOM suits companies looking for a long-term available, industrial-grade basis for their embedded products, in machinery and plant engineering, in medical technology, or in connected sensor applications.

What the qdSOM offers you:

• a marked reduction in development time and cost
• high integration on 29 x 29 mm
• energy-efficient operation (1.0 W typical), also for mobile or battery-powered devices
• industrial suitability through certified components and a robust design
• long-term availability and lifecycle support from querdenker engineering
• support for modern software frameworks, AI integration included (TensorFlow Lite)
