The ATM2 series is available in various packaging options, such as 40-pin QFN, 64-pin DR-QFN, 56-pin QFN, or 37-pin WLCSP, all sharing a common set of features with I/O tailored to each package. The series incorporates an integrated Sensor Hub to read external sensor data and trigger CPU wakeup if thresholds are exceeded.
An independent RF Wakeup Receiver scans for signals, allowing the rest of the SoC to remain in low power. ATM2 supports a range of peripherals like UART, I2C, SPI, Quad SPI, PDM digital microphones, PWM outputs, QDEC for sensor inputs, KSM, Analog Comparator, and ADC through flexible pin mixing. This design caters to diverse IoT applications in consumer, commercial, and industrial markets.
Crafted with meticulous attention to power efficiency, the ATM2 series SoC incorporates a comprehensive array of peripherals and adaptable I/O, catering to diverse applications within the consumer, commercial, and industrial domains of the Internet of Things (IoT) markets.
