DARWIN is a new breed of low-power microcontrollers built to thrive in the rapidly evolving Internet of Things (IoT). They are smart, with the biggest memories in their class and a massively scalable memory architecture. They run forever, thanks to wearable-grade power technology. They are also tough enough to withstand the most advanced cyberattacks. DARWIN microcontrollers are designed to run any application imaginable—in places where you wouldn’t dream of sending other microcontrollers.Generation U microcontrollers are perfect for wearables and IoT applications that cannot afford to compromise power or performance. The MAX32630-MAX32632 feature an Arm®Cortex®-M4 with FPU CPU that delivers ultra-low power, high-efficiency signal processing functionality with significantly reduced power consumption and ease of use.Flexible power modes, an intelligent peripheral management unit (PMU), dynamic clock gating and firmware-controlled power gating optimizes power for the specific application.Multiple SPI, UART, I2C, 1-Wire®master, and USB interfaces are provided. The four-input, 10-bit ADC with selectable references can monitor external sensors.The MAX32631/MAX32632 are secure versions of the MAX32630. They provide a trust protection unit (TPU) with encryption and advanced security features. These include a modular arithmetic accelerator (MAA) for fast ECDSA, a true random number generator, and a hardware AES engine. The MAX32632 also provides a secure bootloader for additional security and life-cycle management.ApplicationsFitness MonitorsPortable Medical DevicesSensor HubsSports WatchesWearable Medical Patches
