PRESS RELEASE:

Redpine Launches MCUs for Smart and Secure IoT Devices

Redpine Signals, Inc. has launched the RS12000 SmartMCU, the industry's first family of MCUs designed specifically to meet the high MIPS, memory and security demands of IoT devices, while at the same time improving battery life compared to traditional ARM Cortex-M4 MCUs. Based on a unique optimized multi-core IoT processor architecture, the new RS12000 SmartMCU family delivers best-in-class performance, ultra-low-power, and highly-secure operation, making it ideal for IoT edge-intelligent, voice assistant-enabled, and network and cloud connected devices.

To achieve this, the RS12000 SmartMCU family features an ARM Cortex M4F running up to 250MHz, sensor hub DSP coprocessor at 125MHz, a four-threaded network security processor based on Redpine's ThreadArch running up to 160MHz, and a full suite of analog and digital peripherals.

"Redpine has fifteen-plus years of deep industry experience developing highly differentiated wireless connectivity solutions for the IoT market, and we have fully leveraged that know-how in our new SmartMCU architecture," said Venkat Mattela, CEO of Redpine Signals. "Existing MCU solutions in the market feature either high-performance or low-power, forcing IoT device designers to choose one mode or utilize multiple MCUs in their designs.

With its unique gear-shifting architecture, Redpine has - for the first time - empowered IoT designers with both high-performance and low-power within a single processor core. By combining this architecture with the RS12000 series' best-in-class trusted execution environment, Redpine is accelerating the development of the next generation of intelligent and wireless connected devices with zero compromise on security."

The RS12000 SmartMCU family's high-performance configurations feature up to four cores and provide double the processing power, memory, and peripherals by including two gear-shifting ARM Cortex M4 processors and two ThreadArch network security processors. As IoT devices are intended to be connected devices, the integrated network security processor includes the ability to run an embedded TCP/IP stack, offloading the primary M4 processor and providing the IoT designer full access to the M4 processor cycles and RAM. In addition – a sensor hub coprocessor at 125MHz accelerates DSP processing (CMSIS-DSP) and machine learning (CMSIS-NN) functions within a local sensor data buffer, thereby freeing up the M4 further.

Based on a trusted execution environment (TEE) architecture with a separate network security processor, secure RS12000 SmartMCU products include suite-B Crypto HW accelerators, secure boot, secure firmware upgrade, secure XIP and secure peripherals. Its high-security levels are ideal for applications such as smart locks, medical devices and secure voice-based ordering.

The RS12000 SmartMCU series' patent-pending gear-shifting is achieved through hierarchical architecture implemented at every level including big and small bus matrices, switching regulators, clock-sources, memory, GPIOs and peripherals, thereby providing optimized transitions between high-performance and low-power operating modes on the same M4 processor core. These ultra-low power capabilities enable battery-operated devices such as smart locks, fitness bands, industrial control units, sensors and location tags to have 3-4x the battery life compared with other solutions.

The RS12000 series includes an "always-on" sensor-hub with hardware accelerators for voice-activity detection (VAD), sensor data collection and capacitive touch. The RS12000 also supports a rich set of digital and analog peripherals including VAD, CAN, Ethernet, eMMC/SD Card, ADC, OpAmps, DAC and USB HS-OTG with PHY. The RS12000 seamlessly interfaces with Redpine's RS9116 wireless connectivity solutions to provide Wi-Fi, dual-mode BT 5 and 802.15.4 connectivity for IoT products. Redpine Signals offers the RS12000 SmartMCU series in QFN, BGA and WLCSP packages. The RS12000 SmartMCU series products are sampling now with volume production starting in Q1 2019.
