The RS6130 is a single chip 60GHz 1T3R FMCW AiP radar sensor with multi-protocol wireless connectivity (BLE5.3/802.15.4/Thread/Matter) inside. The device is portioned into four subsystems, shown in the figure below:

• mmWave Radar Subsystem: This block includes all high-performance radar RF/analog and baseband. It also includes the chirp generator and tx-to-rx finite state machine. HWA is included in baseband, used to offload specified radar processing such as 1D/2D FFT and CFAR.

• 2.4GHz Wireless Connectivity Subsystem: This block contains the whole 2.4G multi-protocol wireless RF, Mod/Demod, Baseband Protocol, and the data interacts with the application CPU via the internal data bus.

• Application Subsystem: It mainly includes one 32-bit RISC-V CPU with FPU and SRAM memory. The CPU connects to SRAM, peripheral interface, and other subsystems via AHB and APB buses. The RISC-V CPU is used to run radar post-processing algorithms, wireless protocols, and other system tasks.

• Power and Clock Subsystem: This chip is a complex single-chip SoC with multiple function systems. We use a single power and clock subsystem for centralized management. It includes several clock sources (including LSI, MSI, DCXO, and SPLL), power blocks (LDOs, BG, and Clamp), and a temperature sensor.

The RS6130 is specifically designed to feature the capability of ultra-low power radar sensing. It contains four main power modes for low power management: shutdown, standby, idle, and active. Our EFSENS™ ultra-low power technology enables the sensor to remain active for more than a year powered by a button battery. Its configuration and data acquisition are enabled via UART/SPI/I2C digital interfaces with other devices.

• Ultra-Low Power: As low as 10μA+ for human presence sensing and 10μA+ for 2.4G wireless connectivity.

• Superior Detection: 1T3R antenna array enables 3D sensing with rich zone perception and zone division; 2.5cm ultra-high range resolution for fine-grained micro-motion sensing (e.g., gestures, breathing/heart rate); 30m ultra-long detection range for large-space coverage.

• Simplified Development: 5-in-1 ultra-high integration (mmWave radar + multi-protocol wireless + PMU + SoC + AiP) with complete SDK and algorithm toolchain for one-stop sensor development, reducing product development cycles and costs.
