STMicroelectronics Reveals Automotive-grade Inertial Modules for Cost-effective Functional-safety Applications up to ASIL B
STMicroelectronics has introduced the ASM330LHBG1 automotive 3-axis accelerometer and 3-axis gyroscope module with a safety-software library that enables a cost-effective solution for functional-safety applications.
意法半導體推出了 ASM330LHBG1 汽車 3 軸加速度計和 3 軸陀螺儀模塊，帶有安全軟件庫，可爲功能安全應用提供經濟實惠的解決方案。
The ASM330LHBG1 is AEC-Q100 Grade-1 qualified for the ambient operating temperature range -40°C to 125°C, allowing use such as next to the engine compartment and in areas exposed to sunlight. The modules deliver high accuracy and reliability for systems such as vehicle navigation, body electronics, in driver support and highly automated driving systems. Typical uses include support for precise positioning in navigation systems, digitally stabilizing cameras, lidars, and radars, and in active suspension, door modules, vehicle-to-everything (V2X) applications, adaptive lighting, and motion-activated functions.
ASM330LHBG1 符合 AEC-Q100 1 級標準，適用於 -40°C 至 125°C 的環境工作溫度範圍，允許在發動機艙旁邊和暴露在陽光下的區域使用。這些模塊爲車輛導航、車身電子設備、駕駛員支持和高度自動駕駛系統等系統提供高精度和可靠性。典型用途包括支持導航系統、數字穩定攝像頭、激光雷達和雷達中的精確定位，以及主動懸架、門模塊、車聯網 (V2X) 應用、自適應照明和運動激活功能。
Equipped with ST's machine-learning core (MLC) and programmable finite state machine (FSM), the ASM330LHBG1 can run artificial intelligence (AI) algorithms in the sensor to provide smart functionality at very low power. This IMU is pin-to-pin compatible and shares the same configuration of registers as ST's automotive IMUs with a lower operating temperature range, permitting a seamless upgrade.
ASM330LHBG1 配備意法半導體的機器學**** (MLC) 和可編程有限狀態機 (FSM)，可以在傳感器中運行人工智能 (AI) 算法，以極低的功耗提供智能功能。該IMU具有引腳間兼容性，與意法半導體的汽車IMU共享相同的寄存器配置，工作溫度範圍較低，可實現無縫升級。
In addition, the modules contain embedded temperature compensation, which ensures stability over wide-ranging operating conditions, and provide a six-channel synchronized output to enhance the accuracy of dead-reckoning algorithms. There are also I2C, MIPI I3C, and SPI serial interfaces, smart programmable interrupts, and a 3KB FIFO that eases managing sensor data to minimize load on the host processor.
此外，這些模塊還包含嵌入式溫度補償，可確保在寬工作條件下的穩定性，並提供六通道同步輸出，以提高航位推算算法的準確性。還有 I2C、MIPI I3C 和 SPI 串行接口、智能可編程中斷和 3KB FIFO，可簡化傳感器數據管理，從而最大限度地減少主機處理器的負載。
The independently tested and certified software adheres to ISO26262 and enables safety-compliant redundancy with two ASM330LHBG1 modules. Fulfilling safety element out of context (SEooC), this combination based on general-purpose hardware supports system certification up to automotive safety integrity level B (ASIL B)[1]. This library provides software for configuring the sensing module, checking for correct operation before starting to acquire data, and handling the acquisition of the data coming from the sensing module. Each of these steps is associated with an error code that provides confirmation if a fault is detected. This solution comprising two identical sensors provides redundancy, checking the data coming from two different sensing sources are consistent.
經過獨立測試和認證的軟件符合 ISO26262 標準，可通過兩個 ASM330LHBG1 模塊實現符合安全要求的冗餘。這種基於通用硬件的組合實現了斷章取義的安全元素 (SEOOC)，支持最高可達汽車安全完整性等級 B (ASIL B) 的系統認證[1]。該庫提供用於配置傳感模塊、在開始採集數據之前檢查操作是否正確以及處理來自傳感模塊的數據採集的軟件。這些步驟中的每一個都與一個錯誤代碼相關聯，該錯誤代碼用於確認是否檢測到故障。該解決方案由兩個相同的傳感器組成，可提供冗餘，檢查來自兩個不同傳感源的數據是否一致。
The ASM330LHBG1 is in production now and available in a 14-lead, 2.5mm x 3mm VFLGA plastic land grid array package. Budgetary pricing is $9.40 for orders of 1000 pieces.
這個 ASM330LHBG1 現已投入量產，採用 14 引腳、2.5 毫米 x 3 毫米 VFLGA 塑料陸地柵格陣列封裝。對於1000件的訂單，預算定價爲9.40美元。
