Baikal Electronics, a Russian semiconductor developer, has announced that the production of its Baikal-U industrial microcontroller is on the brink of one million units during the summer of 2026. This deployment represents one of the largest deployments of domestically developed RISC-V microcontrollers in the country. The company has also disclosed an expanded development roadmap that includes a higher-memory version that is scheduled to be released later this summer, a low-power variant, and a planned transfer of the Zephyr real-time operating system before the end of the third quarter of 2026.
Baikal-U is intended to replace STM32F4 and STM32F7 families from STMicroelectronics, which are extensively used foreign industrial microcontrollers, in Russian industrial automation and embedded systems. This announcement is significant.
Based on domestic RISC-V technology
Baikal-U, in contrast to several previous Russian processors that were reliant on licensed foreign CPU architectures, is constructed on the open RISC-V instruction set architecture, which is based on three processor cores that were developed by the Russian intellectual property company CloudBEAR.
The microcontroller combines two CloudBEAR BR-350 high-performance 32-bit cores running at up to 200 MHz with one CloudBEAR BM-310 core operating at up to 100 MHz. Rather than just augmenting raw computing capacity, each core is assigned a specific function within the controller.
A single BR-350 core is capable of executing real-time control tasks that necessitate deterministic timing, rendering it appropriate for industrial automation and motor control. Operating system services, communication protocols, and application logic are managed by the second BR-350. The BM-310 core is responsible for programmable input/output functions, which enables communication interfaces and peripheral control to operate independently without overwhelming the primary processing cores.
This division of responsibilities is crucial in industrial control systems, as it allows for the simultaneous execution of multiple tasks while ensuring predictable timing.
Built for industrial automation
From the outset, Baikal-U was intended for industrial applications rather than consumer electronics.
Automated process control systems (SCADA and PLC environments), programmable logic controllers, operator control panels, electricity and utility meters, industrial sensors, robotic equipment, motor-control systems, unmanned vehicles, and Internet of Things devices constitute its primary target markets.
The processor is also well-suited for drones and robotic platforms that require precision real-time control of electric motors due to its integrated motor-control capabilities.
Russia has prioritized the replacement of imported electronic components with domestically designed alternatives whenever feasible, as these sectors frequently operate critical infrastructure.
Performance in Comparison to STM32
One of the most notable claims made by Baikal Electronics concerns performance.
The company directly compares the STM32F7x0 family, one of the most extensively used ARM Cortex-M7 industrial microcontrollers worldwide, to Baikal-U.
According to Baikal Electronics, Baikal-U achieves 1,788 CoreMark and 865 DMIPS. The compared STM32F7 device delivers 1,082 CoreMark and 462 DMIPS.
Depending on the specific STM32 model used for comparison, these figures suggest performance improvements of approximately 65% in CoreMark and approximately 87% in DMIPS. In general, the organization asserts that Baikal-U offers a processing performance that is at least 50% superior to that of comparable foreign controllers.
What Do CoreMark and DMIPS Actually Mean?
Although these benchmark numbers may appear abstract, they have a direct impact on the amount of work that a microcontroller can perform.
CoreMark is an industry-standard benchmark that was specifically designed for embedded processors. It quantifies the efficiency with which a processor executes typical embedded duties, such as data processing, state machines, linked lists, and mathematical operations.
A higher CoreMark score indicates that the processor can execute a greater number of embedded software instructions in the same period of time. This translates to the capacity to manage more intricate control algorithms, sensor processing, communications, or robotics applications without necessitating a higher clock speed.
DMIPS, or Dhrystone Million Instructions Per Second Secondly, the Dhrystone benchmark is used to estimate the processor’s general computing capability. Despite being older than CoreMark, it is still extensively used for the purpose of comparing embedded CPUs.
By increasing its DMIPS from 462 to 865, the Baikal-U CPU can perform a significantly greater amount of general-purpose computational work per second.
What Does the Performance Advantage Mean in Practice?
The fact that the benchmark figures are higher does not necessarily imply that a factory machine or robot will operate at a 50–80% faster rate.
Rather, the additional processing capacity offers various practical engineering benefits.
Simultaneously managing communications, diagnostics, and safety monitoring, a single Baikal-U can execute more complex control algorithms. Engineers may no longer require multiple controllers for specific applications, as a single device has the necessary computational capacity to execute multiple functions simultaneously.
In robotic systems, the ability to process sensor inputs more quickly, enhance trajectory calculations, and achieve more precise motion control is facilitated by increased processing capability.
While maintaining a deterministic real-time response, industrial automation systems can accommodate a greater number of communication protocols concurrently.
Advanced vector-control algorithms or adaptive control techniques can be implemented in motor-control applications without exceeding the processor’s capabilities.
Additionally, the enhanced performance provides flexibility for future software upgrades without necessitating hardware replacement.
Consequently, the advantage is not only an increase in benchmark numbers but also an increase in the functional capabilities of the same embedded system.
Competitive Pricing
The microcontroller has been aggressively priced by Baikal Electronics, despite its higher-end performance claims.
Large-volume industrial consumers can obtain pricing starting at approximately 550 rubles, while the recommended price is approximately 950 rubles per unit.
The purpose of this pricing is to ensure that Baikal-U is as competitive as imported STM32-class microcontrollers for industrial manufacturers that purchase tens or hundreds of thousands of controllers annually, while also avoiding the supply uncertainties that are inherent in foreign components.
Features Beyond the CPU
The processor cores are only part of the overall platform.
Baikal-U includes 48 GPIO lines, dual DMA controllers, multiple analog peripherals, including three 12-bit analog-to-digital converters, 192 KB of SRAM, and support for external flash memory in execute-in-place mode. Additionally, it includes 256 KB of embedded flash memory.
The majority of industrial networking and embedded communication requirements are addressed by the communication interfaces, which include USB 2.0 OTG, CAN FD, UART, SPI, QSPI, I²C, and I²S.
The microcontroller also includes built-in support for MicroPython, which enables developers to prototype applications more rapidly before deploying them in production systems.
Increasing Industrial Adoption
The approaching one-million-unit production milestone is indicative of the increasing commercial adoption of the technology, rather than simply prototype development.
In 2026, Baikal Electronics executed one of the most major agreements for domestic industrial microcontrollers in Russia with the industrial automation company REGLAB.
The agreement encompasses the acquisition of a minimum of 1.5 million Baikal-U microcontrollers over a five-year period for the purpose of incorporating them into industrial automation products and programmable logic controllers. Baikal Electronics has disclosed that orders are also being received from manufacturers of industrial automation, telecommunications, and other embedded equipment.
The company has also made technical documentation, such as software development kits, application programming interfaces, hardware reference designs, and development documentation, publicly available. This reduces the obstacles for engineers who are evaluating the platform and aids in the development of a broader software ecosystem that surrounds the processor.
Next Generation Already in the Planning Stage
Baikal Electronics is currently in the process of implementing multiple improvements.
The company anticipates the release of a variant with enhanced on-chip flash memory by the end of summer 2026. Developers can build more sophisticated firmware, incorporate additional communication protocols, and support more intricate industrial software without the need for external memory, as a result of increased flash capacity.
Another product that is in the works is a low-power Baikal-U variant that is designed to be used in energy-efficient embedded systems. Battery-powered industrial sensors, portable instruments, and IoT devices that are required to operate without maintenance for extended periods are particularly dependent on reduced power consumption.
Zephyr RTOS Port Will Expand the Software Ecosystem
The anticipated port of the Zephyr real-time operating system by the end of the third quarter of 2026 is one of the most significant software announcements.
Zephyr is a well-known open-source real-time operating system that is designed for embedded systems and Internet of Things devices. It has supported hundreds of development boards, drivers, and middleware components and has developed a significant international community since its introduction in 2016.
Baikal-U is able to access a vast ecosystem of reusable software by supporting Zephyr, as opposed to relying only on proprietary development environments. Benefiting from ongoing enhancements made by the open-source community, developers can capitalize on existing networking stacks, Bluetooth support, security frameworks, file systems, and hardware abstraction layers.
Compatibility with a widely adopted RTOS significantly reduces the software migration effort and shortens product development cycles for companies that are evaluating Baikal-U as an alternative to imported microcontrollers.
A Strategic Step Beyond Import Substitution
Baikal Electronics is endeavoring to establish an ecosystem that can support industrial automation, robotics, motor control, and embedded computing across a diverse array of Russian industries, in addition to replacing imported microcontrollers. This is achieved through competitive pricing, benchmark results that surpass those of comparable STM32-class devices, and ongoing investment in hardware and software development. Production is rapidly approaching one million units.
The company’s objective is to provide a microcontroller that combines modern architecture, robust processing performance, practical industrial features, and an expanding software environment that can support next-generation automation and intelligent control systems, rather than solely competing on the basis of import substitution.
