  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.

  评估板MAX32630 EVK

  The MAX32630 and MAX32631 evaluation kits (EV kits) provide a convenient platform for evaluating the capa­bilities of the MAX32630–MAX32632 microcontrollers, respectively. While the MAX32630 EV kit includes a MAX32630 soldered directly to the board, the MAX32631 EV kit features a socketed MAX32631. This version can be used to evaluate the MAX32632, but contact the fac­tory for samples. Each EV kit also provides a complete, functional system ideal for development and debugging applications. Except where stated otherwise, the follow­ing sections apply to both EV kits.
