BK3437 Bluetooth 5.0 Dual-Mode SoC – For Customizable Wireless Data Applications

Empower your next-generation connected device with the BK3437, a fully integrated System-on-Chip (SoC) that combines Bluetooth 5.0 Classic and Bluetooth Low Energy (BLE) in a single, power-efficient package. Designed for developers and engineers, this versatile chip provides a complete wireless data solution—from RF transceiver to application microcontroller—streamlining your design process and reducing time-to-market.

The BK3437 integrates a high-performance 2.4GHz radio, an embedded MCU, 160KB of programmable Flash, and a rich set of peripherals (including I2C, SPI, UART, PWM, and ADC) onto a single die. This all-in-one architecture allows you to build robust Bluetooth data links for a wide range of applications, from industrial sensors and smart home controllers to HID devices and audio accessories, without the need for external microcontrollers.

With support for the full 2 Mbps data rate of Bluetooth 5.0, your devices can achieve faster data transfer, improved range, and better coexistence in crowded wireless environments. Operating from a wide 2.0V to 3.6V supply, it is ideal for battery-powered products, and its included Flash memory enables full firmware customization and future-proof over-the-air (OTA) updates.

Key Features & Benefits:

• Bluetooth 5.0 Dual Mode: Supports both Bluetooth Classic (for high-throughput data/audio) and BLE (for ultra-low power connectivity) in one chip, maximizing application flexibility.

• High Level of Integration: Combines RF, baseband, a capable MCU, 160KB Flash, 20KB RAM, and multiple peripherals, minimizing external components and PCB space.

• Complete Development Foundation: The integrated MCU and programmable Flash allow you to run your entire application directly on the BK3437, creating compact and cost-effective designs.

• Rich Hardware Interfaces: Features I2C, SPI, dual UARTs, multi-channel PWM, and a 10-bit ADC for easy connection to sensors, displays, actuators, and other system components.

• Designed for Customization: The programmable architecture and code read protection support secure, tailored firmware development for proprietary or branded products.

• Compact Form Factor: Available in a small 4x4mm QFN-32 package, perfect for space-constrained devices like wearables, modules, and compact IoT nodes.

Ideal For:

• IoT Sensors & Data Loggers

• Smart Home & Automation Devices

• HID Devices (Mice, Keyboards, Remote Controls)

• Wireless Bridges & Adapters

• Industrial Telemetry & Control

• Prototyping & Custom Wireless Solutions
