Bouffalolab WI-FI wireless connection BL616/618

RISC-V architecture: The microcontrol system of BL616/BL618 includes a low-power 32-bit RISC-V CPU with floating point unit, DSP unit, cache and memory, with dynamic frequency configurable from 1MHz to 320MHz. It has 532KB SRAM, 128KB ROM and 4Kb eFuse, embedded 2/4/8MB Flash (optional) and embedded 4/8MB pSRAM (optional).

Ultra-low power consumption: The BL616/BL618 power management unit controls low-power consumption modes, supports two low-power consumption modes: PDS (Power Down Sleep) and HBN (Hibernate), and supports multiple wake-up sources to meet different low-power consumption scenarios.

Leading RF performance: BL616/BL618 integrates 2.4 GHz Wi-Fi (802.11 b/g/n/ax), Bluetooth 5.3 (BLE+BT) and IEEE 802.15.4 wireless connection technology, supports Thread and Zigbee protocols, and can cope with Wider application development scenarios. Supports BLE Wi-Fi fast connection, Wi-Fi/Bluetooth/802.15.4 coexistence. Taking advantage of the characteristics of Wi-Fi 6, BL616/618 can provide higher transmission efficiency and lower power consumption for IoT devices, with a maximum rate of up to 229.4 Mbps. Bluetooth LE supports Coded PHY and 2Mbps PHY, which enables long-distance communication and provides faster communication rates.

Powerful security performance: BL616/BL618 uses image encryption and signature startup, supports XIP QSPI On-The-Fly AES decryption (OTFAD), supports TrustZone, supports AES-CBC/CCM/GCM/XTS mode, MD5, and SHA-1 The /224/256/384/512 algorithm provides a public key accelerator (PKA) for RSA/ECC, supports basic large number operations, and the software provides signature, verification, etc. to meet various security application needs in the field of Internet of Things.

Supports Matter: BL616 integrates Wi-Fi 6, Thread 1.3, Bluetooth 5.2 (BR/EDR/LE) and can be used to build Wi-Fi Matter devices and Thread Matter devices. It can also be used to build more complex Matter gateway devices, such as Thread border routers, Matter/Zigbee bridges, etc.
