RS12200/RS12202/RS12301/RS12302 High Performance SmartMCU


RS12000 SmartMCU™ is the world's first MCU family which "Unifies" low-power and high-performance into a single "gear-shifting" core. Designed at 40 nm, the RS12000 family of SoCs from Redpine Signals, integrate a high performance Cortex® M4F, large memory, high-end security and comprehensive peripherals, while retaining small size and low power. With a ground-up design targeted at IoT, these MCUs simplify the challenges of device developers by providing all features that the myriad of things would need in a single SoC. 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.

RS12200, RS12202, RS12301, RS12302 are SmartMCU™ family's "high-performance" configurations. All of these high performance SoCs have double the memory (800 KB) and double the peripherals (2x USB HS OTG, 2x SD-MEM/SDIO 3.0, 2x Ethernet, etc) of the baseline RS12100 and RS12300 SmartMCU.

RS12202 and RS12302 integrate two ARM® Cortex®-M4F cores with frequency 250 MHz each and two DSP Sensor-hub co-processors at 125 MHz each. The Sensor-hub co-processors accelerate DSP processing (CMSIS-DSP) and machine learning (CMSIS-NN) functions within a local sensor data buffer, thereby freeing up the M4.

Additionally, RS12302 is further optimized for High-throughput networking and features 2x ThreadArch™ 4-threaded network security processors at 160 MHz each. The ThreadArch processors run embedded TCP/IP/SSL stacks, offloading the primary M4 processor and providing the IoT designer full access to the M4 processor cycles and RAM. Also, RS12302 is based on a trusted execution environment (TEE) architecture with a separate security processing subsystem, with high-security levels that are ideal for applications, such as, smart locks, medical devices and secure voice-based ordering.
