EVALUATION KIT AVAILABLE MAX32630MAX32632 Ultra-Low-Power Arm Cortex-M4 with FPU-Based Microcontroller (MCU) with 2MB Flash and 512KB SRAM General Description Benefits and Features DARWIN is a new breed of low-power microcontrollers High-Efficiency Microcontroller for Wearable Devices built to thrive in the rapidly evolving Internet of Things (IoT). Internal Oscillator Operates Up to 96MHz They are smart, with the biggest memories in their class Low Power 4MHz Oscillator System Clock Option and a massively scalable memory architecture. They run for Always-On Monitoring Applications 2MB Flash Memory forever, thanks to wearable-grade power technology. They are also tough enough to withstand the most advanced 512KB SRAM 8KB Instruction Cache cyberattacks. DARWIN microcontrollers are designed to run any application imaginablein places where you 1.2V CPU Core Supply Voltage 1.8V to 3.3V I/O wouldnt dream of sending other microcontrollers. Optional 3.3V 5% USB Supply Voltage Generation U microcontrollers are perfect for wearables Power Management Maximizes Uptime for Battery and IoT applications that cannot afford to compromise Applications power or performance.
