Renesas Electronics Corporation announced the SmartBond DA1470x family of Bluetooth low energy (LE) solutions – the world's most advanced and integrated System-on-Chip (SoC) family for wireless connectivity.
The DA1470x family is the only solution in the Bluetooth LE space that integrates a power management unit, a hardware voice activity detector (VAD), a graphics processing unit (GPU), and Bluetooth LE connectivity on a single chip. This combined functionality provides smart IoT devices with the most advanced sensors and graphics capabilities and continuous, ultra-low-power, always-on audio processing.
The new family is ideal for wearables such as smartwatches and fitness trackers; glucose monitor readers and consumer health and medical devices; household appliances with displays; industrial automation and security systems; and Bluetooth consoles such as e-bikes and gaming equipment.
“The DA1470x family expands our successful strategy of integrating more functions, including increased processing power, expanded memory and enhanced power modules, along with VAD for always-on wake and command word detection,” said Sean McGrath, vice -president of connectivity and audio. Business Division of Renesas IoT, Industrial and Infrastructure Business Unit. “This feature-rich SoC product family enables developers to push the boundaries of connected industrial and consumer applications and future-proof their IoT products to meet the needs of multiple applications by optimizing their bill of materials.”
The high level of integration further results in significant cost savings in the Bill of Materials (BoM), enabling cost-effective system solutions. It also reduces component count on the PCB, enabling smaller form factor designs and freeing up space for additional components or larger batteries. With fewer components on the PCB, system reliability is improved, providing a reduction in the total cost of goods sold (COGS) of the final product.
The SmartBondDA1470x family is already gaining market acceptance. For example, the DA14706 is at the heart of the recently launched Xiaomi Mi Band 7 with an attractive 1.62″ AMOLED display, 192×490, 120 sports modes and 15 days of battery life for typical use.
