Silicon Labs, a leader in IoT connectivity, has consistently set new benchmarks in MCU performance, capabilities, and applications. Today, we're announcing the general availability of the PG26 – a general-purpose microcontroller with a large combination of flash and RAM that features a dedicated matrix vector processor to enhance AI/ML hardware accelerator speeds. This addition to our portfolio is equipped to address a wide array of challenging applications, making it an essential tool for AI/ML-driven applications.

A 32-bit Microcontroller Specifically Designed for Energy-Efficient Embedded Development

The PG26 offers an impressive 3200 kB of flash and 512 kB of RAM, both of which lead Silicon Labs' Series 2 platform. This combination allows for more complex AI/ML models, larger customer applications, and bigger ML models for more accuracy. It also offers a rich peripheral set with a substantial number of GPIOs which enables better system integration. Its 64 GPIOs and four additional analog-only pins reduce the need for external components, which is also facilitated by an integrated LCD driver that can support up to 288 segments. The high performance, multicore compute platform (80MHz Cortex-M33 Core) is also equipped with Secure Vault™ High to improve efficiency and security. Like other Series 2 MCUs, the PG26 is firmware-compatible across the portfolio, making it easier for developers to work across multiple devices. The PG26 maintains the low-power performance Silicon Labs developers are used to, making it an ideal main microcontroller for sensors and home automation devices.

The PG26 MCU Brings Advanced AI/ML Functionality, More Memory, and Additional GPIO

The PG26 provides developers with a wide variety of options to meet diverse application needs. Its low power consumption and small form factor are ideal for energy-sensitive applications. Its precision analog capabilities and integrated LCD are ideal for applications requiring accurate measurements and display functionalities while maintaining low-power performance. The PG26, with its enhanced AI/ML capabilities, more memory, and additional GPIO, is designed for advanced applications that require high processing power and flexibility. Lastly, the latest PG26 offers the most memory, a comprehensive peripheral set, and extensive GPIO options, making it well-suited for complex and memory-intensive applications like industrial automation, predictive maintenance, and monitoring.

The PG26 Microcontroller Makes it Easy to Transition to Embedded IoT Designs

The xG26 platform (BG26, PG26 and the most recently announced MG26) supports a dual strategy, allowing developers to choose between connected and non-connected configurations based on their specific needs. This flexibility ensures that the xG26 can be used in a wide range of applications, from standalone devices to complex IoT systems. One of the key advantages of the xG26 platform is its firmware compatibility and common toolchain across the entire Series 2 portfolio. This ensures that developers can migrate their applications quickly and easily to take advantage of the latest features and improvements without extensive rework. The xG26 platform also offers footprint compatibility, making it easier for developers to upgrade their designs and integrate new features without significant changes to the hardware layout.

Silicon Labs has a rich history of developing cutting-edge microcontrollers, consistently pushing the boundaries of innovation and reliability. The PG26 builds on decades of expertise and technological advancements, bringing Silicon Labs' track record of integrating advanced connectivity features to enable seamless communication with various devices and networks. This combination of robust performance, advanced security, and wireless capabilities makes the xG26 a standout choice for modern applications.
