Product details

Designed for industrial IoT applications, the ATTINY28L-4AUR by Microchip Technology 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 AVR 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 4MHz with <1 A/MHz active current, the microcontroller delivers the perfect balance between performance and energy efficiency for energy-harvesting applications.POR, WDT include advanced security features like cryptographic accelerators and true random number generators, protecting industrial equipment from cyber threats.With 11 programmable as either digital or analog interfaces, the device can directly interface with diverse industrial sensors including 4-20mA loops.2KB (1K x 16) accommodates both the application code and wireless stack, with 20% headroom for future feature expansion in modular industrial controllers.The FLASH implementation supports live firmware updates with rollback protection, ensuring uninterrupted operation during field upgrades.The 2.7V ~ 5.5V range supports direct powering from industrial 24V DC supplies through simple resistive dividers, simplifying power architecture.The Internal design maintains 0.25% frequency accuracy for wireless protocol timing, eliminating the need for external crystal components in space-constrained designs.Rated for -40°C ~ 85°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 32-TQFP format provides 8kV ESD protection on all pins, surviving electrostatic discharges common in plastic injection molding facilities.Available in 32-TQFP (7x7), the microcontroller supports industrial-grade qualification including 1000-hour HTOL testing at 125 C.
