Product details

Silicon Labs's EFM32HG309F32G-C-QFN24 sets new benchmarks in Embedded - Microcontrollers performance, optimized for next-generation automotive electronics. Its radiation-hardened design and exceptional EMI immunity make it the preferred choice for safety-critical vehicle control systems.The ARM® Cortex®-M0+ core architecture incorporates dual instruction pipelines that deliver 1.5 DMIPS/MHz, significantly enhancing computational throughput for autonomous driving algorithms.A 32-Bit Single-Core processing width enables single-cycle execution of complex DSP operations, reducing latency in active noise cancellation systems for premium automotive audio.When clocked at 25MHz, the microcontroller achieves 32-bit floating point operations in just 3 cycles, enabling real-time processing of LiDAR point clouds for ADAS applications.With I²C, IrDA, SmartCard, SPI, UART/USART, USB protocol support, the device forms the backbone of in-vehicle networks, providing deterministic communication between ECUs with <100ns synchronization accuracy.The comprehensive Brown-out Detect/Reset, DMA, I²S, POR, PWM, WDT suite includes automotive-specific features like crank-angle measurement interfaces and injector drive timers, reducing external component count in engine management systems.15 programmable interfaces support mixed-voltage operation from 1.8V to 5V, simplifying integration with legacy automotive sensors and actuators.32KB (32K x 8) of fault-tolerant storage accommodates ASIL-D compliant software architectures with dual-core lockstep implementation for functional safety.The FLASH implementation features ECC protection with single-bit correction capability, ensuring code integrity in high-vibration environments.8K x 8 of parity-protected memory prevents data corruption from alpha particle strikes, meeting ISO 26262 requirements for safety-critical storage.An automotive-grade 1.98V ~ 3.8V range maintains operation during load dump events up to 40V, protecting against voltage transients common in 12V vehicle systems.The A/D 4x12b configuration achieves 90dB SNR for precise battery current sensing in hybrid/electric vehicles, enabling state-of-charge accuracy within 1%.Internal clocking architecture maintains <50ppm frequency stability across the entire automotive temperature range, ensuring reliable CAN bus timing.Qualified for -40°C ~ 85°C (TA), the device operates reliably in dashboard locations where ambient temperatures can exceed 85 C during summer conditions.The Surface Mount option provides superior solder joint reliability for PCB assemblies subjected to thermal cycling in underhood locations.24-VQFN Exposed Pad packaging incorporates copper heat spreaders that reduce junction temperatures by 15 C compared to standard packages in confined spaces.Available in 24-QFN (5x5), the microcontroller supports AEC-Q100 Grade 1 qualification for deployment in safety-relevant automotive systems.
