It provides access to target device-specific web and SDK resources in the Launcher; software and hardware configuration tools; an integrated development environment (IDE) featuring industry-standard code editors, compilers and debuggers; and advanced, value-add tools for network analysis and code-correlated energy profiling.

Find the Right 32-bit Microcontroller for your Application

What is a 32-bit MCU?

Silicon Labs' EFM32™ 32-bit microcontroller (MCU) family is the world's most energy friendly microcontroller and is especially suited for use in low-power and energy sensitive applications, including energy, water, and gas metering, building automation, alarm and security, and portable medical/fitness equipment. Since battery replacement is often not possible for reasons of access and cost, such applications need to operate for as long as possible without external power or operator intervention. Silicon Labs' energy-friendly EFM32 32-bit microcontrollers beat existing low-power MCU alternatives — here we'll highlight the top 5 factors that make this possible.

Low Power Architecture

Get more done with less energy. EFM32 MCUs feature the ARM Cortex® cores with floating-point unit and Flash memory and are architected for low power using only as little as 21 µA/MHz in active mode. The devices are designed to scale power consumption with capabilities in four energy modes, including a deep sleep mode as low as 1.03 µA, with 16 kB RAM retention and operating real-time clock, as well as a 400 nA hibernation mode with 128 bytes of RAM retention and cryotimer.

Functional Density

Reduce the cost of your system with highly integrated microprocessors boasting a rich selection of available high-performance and low-power peripherals, on-chip non-volatile memory, scalable memory footprints, crystal-less 500 ppm sleep timer, and integrated power-management functions.

Security

When you want your products to withstand the most challenging cyber-security attacks, you can trust Silicon Labs' technology to safeguard your customers' privacy.

When considering security in the context of IoT, there are multiple aspects a developer needs to consider.

Encryption is only as strong as the security offered by the physical device itself. The easiest device attack is a remote attack on software to inject malware which is why a hardware root of trust secure boot is critical. Many IoT devices are easily acquired in the supply chain and allow “Hands-On”, or “Local” attacks which allows attacking the debug port or using physical attacks like side-channel analysis to recover keys during communication encryption.
