Product details
STMicroelectronics's STA1085EOA redefines power efficiency in the Embedded - Microprocessors segment, crafted for energy-harvesting IoT endpoints. This ultra-low-power microprocessor combines near-threshold voltage operation with intelligent power gating, achieving microampere-level standby currents for decade-long battery life in wireless sensor nodes.The ARM® Cortex®-R4 ultra-low-power core maintains full register retention at subthreshold voltages, enabling seamless operation from energy harvesting sources.Designed with 1 Core, 32-Bit configuration, the processor optimizes power distribution across multiple low-power domains.Operating at 450MHz in burst modes, the device balances performance and power consumption for intermittent computing applications.The ARM® Cortex®-M3 sensor hub offloads signal processing tasks at microamp current levels.The SDRAM memory architecture implements state-retentive power gating for zero-leakage data preservation during sleep modes.Yes display controller operates with adaptive refresh rates to minimize power consumption in e-paper applications.LCD, Touchscreen interfaces support direct connection to ultra-low-power displays common in wearable devices.The USB 2.0 (1) interface implements low-power link states while maintaining instant wake-on-connect functionality.3.3V flexible I/O banks allow direct interfacing with energy harvesting circuits without level shifters.Specified for -40°C ~ 85°C (TA) operation, the processor maintains functionality in environmental monitoring applications.The 361-LFBGA package minimizes thermal mass for rapid wake-up from deep sleep states.Offered in 361-LFBGA (16x16), the device supports thin-film battery integration in wearable designs.
