Description
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 UP microcontrollers are designed to handle the increasingly complex applications demanded by today’s advanced battery-powered devices and wireless sensors. The MAX32650–MAX32652 are ultra-low power memory-scalable microcontrollers designed specifically for high-performance, battery-powered applications. They are based on Arm® Cortex®-M4 with FPU CPU with 3MB flash and 1MB SRAM. Memory scalability is supported with multiple memory-expansion interfaces, including a HyperBus™/Xccela™ DDR interface and two SPI execute in place (SPix) interfaces. A secure digital interface supports external high-speed memory cards, including SD, SDIO, MMC, SDHC, and microSD™.
Power-management features provide five low-power modes for clock, peripheral, and voltage control. Individual SRAM banks of 32KB, 96KB, or 1024KB (full retention) can be retained with reduced power consumption. A SmartDMA performs complex background processing while the CPU is off to dramatically reduce overall power consumption.
The MAX32651 is a secure version with a trust protection unit (TPU) which provides a modular arithmetic accelerator (MAA) for fast ECDSA, an AES engine, TRNG, SHA-256 hash, and secure bootloader. A memory decryption integrity unit (MDIU) provides on-the-fly data decryption (plain or executable) stored in external flash.
The MAX32652 is packaged in a high-density, 0.35mm pitch, 140-bump WLP targeted for tiny form factor products that require high I/O counts.
