MCU widens capabilities of IoT applications

The microcontroller is based on an Arm Cortex-M4 core with a floating point unit (FPU) and supports a future-proof memory architecture that enables designers to grow the capabilities of their Internet of Things (IoT) device applications.

The memory-scalable device integrates 3MBytes of flash, 1MByte of SRAM, and a clock running up to 120MHz.

Low-power SRAM retention modes help extend battery life, and the low-power active mode features advanced power management capabilities.

Additional memory expansion is available through external memory using the device’s 120MBytes-per-second HyperBus/XcellaBus DDR interface.

The microcontroller provides a range of high-speed peripherals, including high-speed USB 2.0, an SD card controller, and a TFT display.

Additional serial interfaces include dedicated FIFOs that enable communication to external sensors, a four-input, 10-bit analogue-to-digital converter (ADC) that monitors system power, and an I²S port that supports bi-directional audio streaming.

The device also leverages Maxim's best-in-class security toolbox to help create secure sensors for IoT applications.

It is ideal for applications such as fitness monitors, wearable medical patches, portable medical devices, industrial sensors, and other battery-powered IoT devices.

The microcontroller is supported by the MAX32650 Evaluation Kit, also available to order from Mouser.

The kit contains a MAX32650 microcontroller with a pre-programmed demo, JTAG debugger with ribbon cable, and two USB cables.
