低功耗藍牙晶片
Silicon Labs 推出其低功耗藍牙系統單晶片
Silicon Labs 推出 BG2B，一款 Series 2 藍牙低功耗系統單晶片，專為小巧、電池供電的物聯網裝置而設計。該晶片採用公司最低功耗的藍牙架構，以延長電池壽命，同時整合 Secure Vault 安全功能及進階藍牙信道探測（Channel Sounding）技術。
BG2B 結合雙 12 位元類比數位轉換器、CAN-FD、內置 LED 驅動器及雙輸出直流轉直流電源架構，減少外部元件並簡化裝置設計。它亦支援符合 Apple 及 Google 規格的進階信道探測功能，配合免版稅測距程式庫及較短的探測步驟時間，以降低能源消耗。Secure Vault 則保障裝置身分識別、韌體及加密密鑰，並可透過 Silicon Labs 的生產服務提供安全佈建。
對開發人員而言，BG2B 可減少物料清單需求，同時以更強的安全性及更長的電池壽命，支援感測器、資產標籤、電子貨架標籤、智能家居裝置及車輛診斷應用。
英文原文
Silicon Labs introduced the BG2B, a Series 2 Bluetooth Low Energy system-on-chip designed for compact, battery-powered IoT devices. The chip uses the company’s lowest-power Bluetooth architecture to support longer battery life while integrating Secure Vault security and advanced Bluetooth Channel Sounding capabilities.
BG2B combines dual 12-bit ADCs, CAN-FD, integrated LED drivers and a dual-output DC-DC power architecture to reduce external components and simplify device design. It also supports advanced Channel Sounding features aligned with Apple and Google specifications, alongside a royalty-free ranging library and shorter sounding step timings designed to reduce energy use. Secure Vault protects device identities, firmware and cryptographic keys, with secure provisioning available through Silicon Labs’ manufacturing services.
For developers, BG2B can reduce bill-of-materials requirements while supporting sensors, asset tags, electronic shelf labels, smart-home devices and vehicle diagnostics with stronger security and longer battery life.
