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 would not dream of sending other micro controllers.
Generation U microcontrollers are perfect for wearables and IoT applications that cannot afford to compromise power or performance. The MAX32620/MAX32621 feature an Arm® Cortex®-M4 with FPU CPU that delivers high-efficiency signal processing, ultra-low power consumption and ease of use.
Flexible power modes, an intelligent PMU, and dynamic clock and power gating optimize performance and power consumption for each application. Internal oscillators run at 96MHz for high-performance or 4MHz to maximize battery life in applications requiring always-on monitoring.
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.
All versions provide a hardware AES engine. The MAX32621 is provides a secure trust protection unit (TPU) with a modular arithmetic accelerator (MAA) for fast ECDSA, a hardware PRNG entropy generator, and a secure boot loader. The MAX32620L provides a reduced 1MB of flash memory.
This data sheet applies to revision C and later. Legacy mode operation provides compatibility with revision A.
