High-Performance Rugged Box PC
The BL74A features 13th Gen Intel Core processors with up to 14 cores (6P+8E) and up to 96 GB of soldered dual-channel DDR5-5200 IBECC RAM. Introducing Intel's new hybrid architecture with a combination of Performance and Efficiency cores, the BL74A offers a scalable CPU performance to perfectly suit operational needs, even in harsh ambient temperatures of up to +70 °C (+85 °C for 10 min.). The BL74A is an excellent choice for demanding data processing and communication applications including virtualization, passenger internet access and intelligent CCTV supported by AI inference.
Gateway to Embedded AI
The highlight of the BL74A is the integrated Metis(TM) AIPU (Artificial Intelligence Processing Unit) by Axelera AI. It is an outstanding solution on a new speed level for challenging and fast embedded AI applications (e.g. CCTV with object and anomaly detection) and much more powerful than the normal GPU integrated on the CPU. The box PC is equipped with one AIPU module to boost performance.
Fanless Operation
The rugged aluminum housing is optimized for conduction cooled (fanless) operation in high ambient temperatures. Deep cooling fins help to generate hot air flow away from the housing in a chimney effect. This results in a homogeneous heat distribution without hot spots. The BL74A can dissipate up to 95 W of thermal power at +70 °C ambient.
Comprehensive Management
A versatile board management controller provides intelligent monitoring and supervision of all vital signals including supply and on-board voltages, temperatures, and a watchdog for the OS.
Additionally, the BL74A supports Intel AMT remote out-of-band management and holds a discrete TPM module for hardware based system security.
This Product is Coming Soon
The BL74A will be available once conformity assessments are completed.
