Product details
Designed for industrial IoT applications, the W78C438C40FL by Nuvoton Technology Corporation redefines performance in Embedded - Microcontrollers. Its ultra-low power architecture and robust RF coexistence capabilities make it ideal for wireless sensor networks in smart factory environments.The 8051 core implements dynamic voltage scaling that reduces active power by 40% compared to fixed-voltage designs, extending battery life in remote monitoring nodes.A 8-Bit architecture with single-cycle multiply-accumulate units accelerates FFT computations for vibration analysis in predictive maintenance applications.Operating at 40MHz with <1 A/MHz active current, the microcontroller delivers the perfect balance between performance and energy efficiency for energy-harvesting applications.The EBI/EMI, Serial Port interfaces incorporate galvanic isolation support, enabling direct connection to industrial fieldbus networks without external isolation components.With 40 programmable as either digital or analog interfaces, the device can directly interface with diverse industrial sensors including 4-20mA loops.The ROMless implementation supports live firmware updates with rollback protection, ensuring uninterrupted operation during field upgrades.256 x 8 of retention RAM maintains context during deep sleep modes, enabling instant wake-up response to critical process events.The 4.5V ~ 5.5V range supports direct powering from industrial 24V DC supplies through simple resistive dividers, simplifying power architecture.The External design maintains 0.25% frequency accuracy for wireless protocol timing, eliminating the need for external crystal components in space-constrained designs.Rated for 0°C ~ 70°C (TA), the device operates reliably in foundry environments where ambient temperatures can fluctuate rapidly.Surface Mount packaging withstands repeated thermal shock from -40 C to 125 C, meeting reliability requirements for outdoor industrial installations.The 100-QFP format provides 8kV ESD protection on all pins, surviving electrostatic discharges common in plastic injection molding facilities.
