Renesas introduces its first dual-core Bluetooth low-power SoC with integrated flash memory and minimal power consumption

     Renesas Electronics announced the launch of the DA14592 Bluetooth Low Energy (LE) system-on-chip (SoC), Renesas' lowest power consumption and smallest multi-core (Cortex-M33, Cortex-M0+) Bluetooth Low energy product. Thanks to the careful trade-off between on-chip memory (RAM/ROM/ flash) and SoC chip size (which determines cost), the DA14592 is well suited for a wide range of applications including connected healthcare, asset tracking, HMI devices, metering, PoS readers, and "crowdsourced location (CSL)" tracking.

     The DA14592 continues Renesas Bluetooth Low Energy SoC's leadership in lowest radio power consumption with a new low power mode that delivers industry-leading 2.3mA radio transmit current and 1.2mA radio receive current at 0dBm. In addition, it supports ultra-low sleep currents of only 90nA, extending the operation and service life of battery-powered end products, and supports ultra-low operating currents of 34µA/MHz for products that need to handle a large number of applications.

     From a solution cost perspective, the DA14592 typically requires only six external components, resulting in a class-ideal engineering Bill of Materials (eBOM). The product uses only system clock and high-precision on-chip RCX, eliminating the need for sleep mode crystals in most applications. The lower eBOM, combined with the DA14592's small package (WLCSP: 3.32mm x 2.48mm, and FCQFN: 5.1mm x 4.3mm), also creates an attractive solution for designers in small sizes. The DA14592 also includes a high-precision, sigma-delta ADC and up to 32 GPIOs. Unlike other SOCs in its class, it also offers a QSPI that supports expansion of external memory (flash or RAM) for applications that require additional memory.

     Renesas has integrated all the external components needed to implement a Bluetooth Low Energy solution into the DA14592MOD module, providing customers with the fastest time to market and lower overall project costs. The design of the module is focused on ensuring maximum design flexibility: the functionality of the DA14592 is fully routed outside the module, and tooth pins are used for easy/low-cost installation of the module during development.

     "Crowdsourcing" targeting is a key application of Renesas' DA14592 and DA14592MOD demonstrations. Apple's AirTag sales in North America alone are expected to reach more than $29 billion by 2031. Google also recently announced plans to build a crowdsourced location network called Find My Device. Renesas is committed to providing a best-in-class reference design for both mobile operating systems immediately after the launch of Google's Find My Device network, delivering industry-leading power consumption, eBOM and solution footprint. These reference designs will not only accelerate label design, but also allow manufacturers to easily attach DA14592 to their products that are vulnerable to loss or theft, enabling global positioning of products with billions of smartphones to differentiate their products and enhance value for end customers. Using the DA14592MOD will also eliminate the need for global regulatory certification, reducing development costs and further accelerating time-to-market.

     Davin Lee, Sr. Vice President and General Manager of the Analog and Connectivity Product Group for Renesas said: "With Renesas' signature low-power features and the best-in-class eBOM, the DA14592 and DA14592MOD extend our preeminence in Bluetooth low-power SoCs. In addition, we actively listen to customer feedback, continue to expand product support, and bring reference designs for applications such as crowdsourcing targeting to help customers more easily achieve product differentiation and create superior value while maintaining the lowest cost."
