The RS6240 is a single-chip 60 GHz 2T4R FMCW AiP MIMO radar sensor with 2.4 GHz wireless connectivity (BLE 5.3 / 802.15.4 / Thread / Matter) integrated. The device is partitioned into four subsystems, shown in the figure below:

• mmWave Radar Subsystem: This block includes all high-performance radar RF/analog and baseband. It also incorporates the chirp generator and TX-to-RX finite-state machine. A Hardware Accelerator (HWA) is embedded in the baseband to offload specified radar processing such as 1D/2D-FFT and CFAR.

• 2.4 GHz Wireless Connectivity Subsystem: This block contains the complete 2.4 GHz multi-protocol wireless RF, modulator/demodulator, baseband protocol stack, and exchanges data with the application CPU through the internal data bus.

• Application Subsystem: It mainly comprises two 32-bit RISC-V CPU cores with DSP, FPU, and I/D-cache. The CPUs connect to SRAM, peripheral interfaces, and other subsystems via AHB and APB buses, executing radar post-processing algorithms, wireless protocols, and additional system tasks.

• Power and Clock Subsystem: As a complex single-chip SoC integrating multiple functional systems, the RS6240 employs a unified power and clock subsystem for centralized management. It provides several clock sources (LSI, MSI, crystal oscillator, SPLL) and power blocks (LDOs, band-gap, clamp).

The RS6240 is specifically designed for low-power, high-accuracy radar sensing applications. It offers four main power modes—shutdown, standby, idle, and active—for efficient power management. Configuration and data acquisition are enabled through UART, SPI, I²C, CAN-FD, and LIN digital interfaces.

Enhanced Energy Efficiency:
• Dual-core RISC-V CPU with FPU/DSP extensions and built-in radar RSP hardware accelerator
• Power consumption <0.2W, no overheating 

Superior Detection:
• 2T4R antenna array enables 4D sensing with advanced zone perception and zone division
• 2cm ultra-high range resolution for fine-grained micro-motion sensing (e.g., gestures, breathing/heart rate)
• 40m 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 development, reducing product development cycles and costs.
