The BL602 has a built-in RISC-V 32-bit single-core processor with a clock frequency of up to 192MHz, including 64 interrupts and an interrupt controller with 16 interrupt levels/priorities for low-latency interrupt processing. With 276KB RAM / 128KB ROM / 1Kb eFuse, support external Flash. A variety of integrated peripherals and rich GPIO pins meet the functional requirements of various IoT products. In addition, the operating temperature of -30°C~105°C also expands the application scenarios of BL602.

The BL602 integrates 2.4 GHz Wi-Fi and long-range Bluetooth 5 (LE), supports simultaneous access to multiple clouds, supports Bluetooth Mesh, and maintains excellent RF performance at higher operating temperatures, helping build IoT devices and solutions with wider coverage and more powerful application functions.

BL602 supports the use of ECC-256 signed images to provide secure boot protection; supports QSPI/SPI Flash instant AES decryption (OTFAD), supports AES128 CTR mode, supports AES 128/192/256-bit encryption engine to ensure secure device connection; provides public key Accelerator (PKA), supports basic operations of large numbers, and the software provides signature, verification, etc. to ensure the security of the application program interface.

BL602 uses the IoT development framework BL_IOT_SDK. BL_IOT_SDK has undergone rigorous application testing and has been successfully applied to tens of millions of IoT devices. Based on its mature and clear software architecture, complete API and easy-to-use tools, developers will be easier to build BL602 applications or port solutions to other platforms. The Wi-Fi SDK of BL602 supports Wi-Fi client mode, access point mode or coexistence mode. Together with the BLE SDK, it builds rich IoT connection functions and realizes more smart interconnected applications.
