Wearable Health Monitors
With 320KB RAM and low-power modes, this MCU can buffer continuous sensor data (ECG, PPG) and run algorithms at 120MHz, while driving a small LCD.
Smart Meters
Use the low voltage operation and LCD driver to create energy meters with real-time display, processing metrology data efficiently.
IoT Edge Nodes
Combine the Cortex-M4 with low-power communication (LPUART) to process sensor data locally and transmit only relevant information, extending battery life.
Portable Instrumentation
The 320KB RAM allows large data buffers for oscilloscopes or multimeters, while the FPU handles signal processing.
Access Control Panels
Drive a keypad and LCD, while managing multiple authentication protocols (fingerprint, RFID) with the high-speed core.
Environmental Sensors
Log temperature, humidity, and gas readings to external flash, using the DMA to minimize power consumption.
