瑞萨电子推出全球功耗最低、体积最小的多核低功耗蓝牙SoC DA14592，用于众包定位等应用。这款集成闪存的双核低功耗蓝牙SoC，采用了全新低功耗模式，实现了在0dBm时的2.3mA无线电发射电流和1.2mA无线电接收电流。此外，它还支持90nA的休眠电流，延长了依赖电池供电的终端产品的工作和使用寿命。
DA14592还具有高精度片上RCX，消除了大多数应用中对睡眠模式晶体的需求。它采用小型封装（WLCSP：3.32mm×2.48mm，和FCQFN：5.1mm×4.3mm），为设计人员构建了小尺寸解决方案。此外，DA14592还包括一个高精度、sigma-delta ADC和多达32个GPIO。与同类其它SoC不同的是，它还提供一个支持外部存储器（闪存或RAM）扩展的QSPI，以满足需要额外存储器的应用。
瑞萨电子已将实施低功耗蓝牙解决方案所需的所有外部组件集成至DA14592MOD模块中，该模块的设计重点在于确保最大的设计灵活性：将DA14592的功能全面路由到模块外部，并使用齿形引脚以便在开发过程中低成本地安装模块。DA14592现已量产，预计将于2024年二季度通过全球监管认证。

Title: Renesas Electronics Unveils World’s Smallest Power-Constrained Bluetooth SoC, Driving Innovation in Crowd-Sourcing Localization
Keywords: 1. Renesas Electronics launches power-efficient Bluetooth SoC
News Content: Renesas Electronics has introduced the world’s smallest, multi-core, and power-efficient Bluetooth SoC, DA14592, designed for applications such as crowd-sourced localization. This dual-core low-power Bluetooth SoC with integrated flash memory features a new low-power mode that achieves a radio transmit current of 2.3mA at 0dBm and a radio receive current of 1.2mA. In addition, it supports a sleep current of 90nA, extending the operational life of battery-dependent terminal products.
DA14592 also includes a high-precision on-chip RCX, eliminating the need for sleep mode crystals in most applications. It offers small package options (WLCSP: 3.32mm×2.48mm and FCQFN: 5.1mm×4.3mm) to designers building compact solutions. Moreover, DA14592 includes an accurate, sigma-delta ADC and up to 32GPIOs. Unlike other similar SoCs, it also provides an external QSPI that supports additional memory (flash or RAM) expansion to meet applications requiring additional storage.
Renesas Electronics has integrated all external components required for implementing low-power Bluetooth solutions into the DA14592MOD module. The module’s design emphasizes maximum design flexibility by fully routeling the functions of DA14592 outside the module and using serrated pins for cost-effective module installation during development. DA14592 is now in mass production and is expected to pass global regulatory certification in the second quarter of 2024.
