Product description
The MTK MT5921A/A is a highly integrated Bluetooth Low Energy (BLE) System-on-Chip (SoC) that provides robust wireless connectivity and energy efficiency, making it ideal for a variety of Bluetooth-enabled devices. With Bluetooth 4.2 and Bluetooth 5.0 support, it provides enhanced communication capabilities, including improved data throughput, extended range, and lower latency compared to older Bluetooth versions.
By supporting Bluetooth 5.0, the MT5921A/A enables devices to communicate over extended distances, making it well-suited for applications like smart home systems, industrial IoT networks, and long-range asset tracking. Bluetooth 5.0’s faster data transfer rate allows the chip to handle larger volumes of data more efficiently, improving overall system performance and user experience.
The MT5921A/A offers an integrated architecture that combines the Bluetooth radio, baseband processor, and protocol stack into a single chip. This integration reduces the need for additional components, simplifying the design process and lowering overall system costs. It also reduces the physical size of the end device, making it ideal for space-constrained applications such as wearables and sensor-based systems.
Power consumption is a critical factor in battery-powered devices, and the MT5921A/A excels in this area. With ultra-low standby current of less than 1 µA, it ensures that devices can remain in a low-power state when not in active use, significantly extending battery life. During active communication, the chip consumes less than 10 mA, making it perfect for applications that need to operate for extended periods without frequent recharging, such as fitness trackers, health monitors, and smart home sensors.The MT5921A/A supports multiple interface options, including SPI, I2C, UART, and GPIO, which allows for easy integration with a wide range of external peripherals such as sensors, displays, and processors. This versatility makes it suitable for a broad array of applications across various industries, from healthcare to smart homes and industrial IoT.
