RS12000 SmartMCU™ series is the world's first MCU family which "Unifies" low-power and high-performance into a single gear-shifting core. Designed at 40 nm, RS12000 series 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 RS12100 and RS12300 are the first two chips of the RS12000 SmartMCU™ family. The RS12100 and RS12300 SmartMCUs, both integrate an ARM® Cortex® M4F with frequency variants of up to 250 MHz, SRAM of 400 KB and flash up to 4 MBytes. In addition, they integrate a DSP sensor hub co-processor at 125 MHz that accelerates DSP processing (CMSIS-DSP) and machine learning (CMSIS-NN) functions within a local sensor data buffer, thereby freeing up the M4.

In addition, the RS12300 is further optimized for secure and network connected IoT devices, with the MCU running the network stacks. The RS12300 integrates a four-threaded network security processor at 160 MHz,with 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. Also, RS12300 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.
