STR912FAW44X6 Microcontroller IC 16/32-Bit 96MHz 512KB (512K x 8) FLASH
The STR912FAW44X6 is a high-performance 1 6/32-bit ARM966E-S™ RISC microcontroller designed by STMicroelectronics for industrial automation, embedded networking, and precision measurement applications. Built on a 96MHz ARM9 core with a 5-stage pipeline and Harvard architecture, it achieves up to 96 MIPS processing power while maintaining compatibility with ARM7 Thumb instruction sets for legacy code reuse. The device integrates dual-bank Flash memory (512KB main + 128KB secondary) and 96KB SRAM, supporting battery backup for critical data retention. Its low-power design (50μA sleep mode) and industrial-grade temperature range (-40°C to 85°C) make it ideal for harsh environments, such as factory automation and outdoor monitoring systems.
STR912FAW44X6 MCU Typical Applications
The STR912FAW44X6 excels in demanding embedded scenarios requiring real-time processing and multi-protocol connectivity. Key use cases include:
1. Industrial Automation: PLC controllers, robotic actuators, and sensor hubs leveraging its CAN/Ethernet networking and motor control PWMs.
2. Precision Measurement: High-speed data acquisition systems, such as the documented barcode-based digital leveling instrument, which achieved ±0.0185mm measurement accuracy using its ADC and DMA-driven Ethernet upload.
3. Communication Gateways: Edge devices aggregating CAN, USB, and Ethernet traffic in smart grid or fleet management systems.
4. Embedded Vision: Low-latency image processing platforms combining its ARM9 core with external CMOS sensors via I²C/SPI interfaces.
