WISEN-1 2.4GHz, 1T1R, Wi-Fi 6 + BLE 5
Low-power Wi-Fi & BLE Combo with Application MCU
WISEN-1 is a highly integrated 1T1R 2.4GHz Wi-Fi 6 + BLE 5.1 combo chip and MCU-based SoC solution for ultra-low-cost and low-power IoT applications. WISEN-1’s excellent communication range and low power makes it theideal solution for low power applications such as Smart-home (remote monitoring and sensing), battery IPC, visual
Doorbell, connected home appliance, etc.
The application processor subsystem contains a high-performance 32-bit RISC-V MCU which operates up to 160MHz and it includes embedded SRAM/ROM. The Wi-Fi subsystem contains a 2.4GHz radio and 802.11b/g/n/ax modem/MAC to achieve low latency, long range and low power consumption. The Bluetooth LE subsystem contains a Bluetooth 5.1 radio, modem and link controller, as well as Bluetooth mesh feature.
WISEN-1 enables ultra-small form factor solutions with minimal external components, reducing total silicon and system-level costs. An extensive range of peripheral interfaces and security features are fully supported by this SoC solution. Advanced connectivity and power management techniques enable extremely low active and sleep power consumption, thus extending the useful life of battery-powered devices.
