Broadcom BK7235 processor combines with OpenHarmony



OpenHarmony Broadcom BK7235 processor

Broadcom Integration Group recently launched a new BK7235 high-end processor and merged it with the OpenHarmony operating system. The chipset aims to enhance IoT connectivity and bring new improvements in the security aspects.

OpenHarmony is well-known for its compatible connections as well as all-scenario operations. It contains an advanced and tech-pack connectivity system that can support all smart devices effectively.

And to make these connections more reliable, Broadcom group has integrated a BK7235 processor in the OpenHarmony framework. Accordingly, it will facilitate the operating system with rich storage and a robust security structure.

On the other hand, it can provide numerous immediate options for commercial purposes. For instance, lightweight audio quality, new upgrades for functions, controlling management, and more.


Let’s understand the high-end BK7235 processor in detail.

BK7235 MCU Chipset – Two Versions

Broadcom BK7235 chip is an MCU (micro-controller unit). It has two variants: single-core and dual-core. The single-core chip installs a 656KB RAM and supports 26 GPIOs (General Purpose Input/Output), and a 5V direct power supply. It is appropriate for 5V smart home gadgets.

Meanwhile, the BK7235 dual-core version packs 800KB RAM and a high-speed 8MB Dynamic RAM (DRAM). Further, it supports single and multiple cloud connections, 48 GPIOs, dual microphones, a CIS camera, 16-bit LCD, and significant coding functions.

BK7235 processor – efficiency

Both versions use a self-developed security infrastructure to offer tough security protection for the entire operating system. Aside from the regular security components, the processor also equips the powerful P-384 encryption protocol to access verified algorithms.


It’s worth mentioning that the respective chipset has also qualified for the PSA level 1 safety certification. Hence, it will make useful changes in the OpenHarmony operating system.

Moreover, the processor easily operates and manages common, commercial, and authorized passwords. For instance AES, RSA, ECC, SM2, SM3, SM4, and more. Together, these qualities will help in providing efficient security protection to the IoT and other network devices.

In addition to the magnificent safety functions, the BK7235 chip is eligible for Wi-Fi 6, and Bluetooth 5.2, and supports various third-party network connections. Hence, the chipset could prove a beneficial implementation for the OpenHarmony community.
