Chip Introduction

BL616/618 is a Wi-Fi 6+Bluetooth 5.3 (LE)+802.15.4 (Zigbee/Thread) triple chip suitable for ultra-low power applications, with a 32-bit RISC-V CPU with a maximum dominant frequency of 320M and with floating point unit and DSP unit, providing industry-leading wireless and computing performance for Internet of Things applications. In addition, the chip has rich peripheral interfaces, including DVP, MJPEG, Display, Audio Codec, USB2.0, SDU, Ethernet (EMAC), SD/MMC (SDH), SPI, UART, I2C, I2S, PWM, GPDAC, GPADC, ACOMP, etc., which can be applied to multimedia and industrial fields such as audio and video.

• RISC-V Architecture

  The micro-control system of BL616/BL618 includes a low-power 32-bit RISC-V CPU with floating point unit, DSP unit, cache and memory. The dynamic frequency can be configured from 1MHz to 320MHz. BL616/618 with 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 mode, supports PDS (Power Down Sleep) and HBN (Hibernate) low power consumption modes, 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 technologies, supports Thread and Zigbee protocols, and can cope with broader application development scenarios. Support BLE's Wi-Fi fast connection, Wi-Fi/Bluetooth/802.15.4 coexistence. f Wi-Fi 6, BL616/618 can provide higher transmission efficiency and lower power consumption for Internet of Things devices, with a maximum rate of 229.4 Mbps. Bluetooth LE supports Coded PHY and 2Mbps PHY, which can realize long-distance communication and provide faster communication rate.

  

• Strong Security Performance

  BL616/BL618 adopts image encryption and signature startup, supports XIP QSPI On-The-Fly AES decryption (OTFAD), supports TrustZone, AES-CBC/CCM/GCM/XTS mode, MD5, SHA-1/224/256/384/512 algorithm.

  It provides public key accelerator (PKA) for RSA/ECC, supports large number basic operations, and software provides signature, verification, etc. to meet various security application requirements in the field of the Internet of Things.

  

• Support Matter

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