AUSTIN, Texas--(BUSINESS WIRE)--Delivering the next generation of Gecko technology for the Internet of Things (IoT), Silicon Labs (NASDAQ: SLAB) has introduced two new EFM32™ Gecko microcontroller (MCU) families that provide advancements in security and energy management technologies. The new Jade Gecko and Pearl Gecko MCUs combine a state-of-the-art hardware cryptography engine, flexible low-energy modes, an on-chip dc-dc converter and scalable memory options backed by Silicon Labs’ developer-friendly Simplicity Studio™ tools. EFM32 Jade and Pearl Gecko MCUs target an array of energy-sensitive and battery-powered devices including wearable health and fitness trackers, smart door locks, point-of-sale devices, security sensors and other IoT node applications.

Securing IoT Nodes

Jade and Pearl Gecko MCUs address the growing need to equip IoT-connected devices with the latest security technologies to thwart hackers. The new MCUs feature a hardware cryptography engine providing fast, energy-efficient, autonomous encryption and decryption for Internet security protocols such as TLS/SSL with minimal CPU intervention—and without sacrificing battery life. The on-chip crypto-accelerator supports advanced algorithms such as AES with 128- or 256-bit keys, elliptical curve cryptography (ECC), SHA-1 and SHA-224/256. Hardware cryptography enables developers to meet evolving IoT security requirements more efficiently than with conventional software-only techniques often required by competing MCUs.

Minimizing Energy Consumption

Based respectively on ARM® Cortex®-M3 and M4 cores, Jade and Pearl Gecko MCUs provide ample performance for connected devices while enabling developers to optimize battery life or use smaller batteries for space-constrained designs. The new MCUs feature an enhanced peripheral reflex system (PRS) that lets low-power peripherals operate autonomously while the MCU core sleeps, allowing connected devices to sleep longer, thus extending battery life. Energy-saving low active-mode current (63 µA/MHz) enables computationally intensive tasks to execute faster. Low sleep-mode current (1.4 µA down to 30 nA) and ultra-fast wake-up/sleep transitions further minimize energy consumption.

Jade and Pearl Gecko MCUs also integrate a high-efficiency dc-dc buck converter. Offering a total current capacity of 200 mA, the on-chip converter can provide a power rail for other system components in addition to powering the MCU. This power management innovation reduces bill-of-materials (BOM) cost and board area by eliminating the need for an external dc-dc converter.

“IoT developers are seeking not only advanced power management architectures to extend the battery life of connected devices but also next-generation cryptography technologies to help secure IoT node applications,” said Daniel Cooley, vice president of marketing for IoT products at Silicon Labs. “With connected devices facing ever-increasing security threats, developers must safeguard their IoT products with leading-edge hardware cryptography. We designed our Pearl and Jade Gecko MCU families from the ground up to address these two critical IoT application requirements – energy efficiency and security.”
