General 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 you can imagine—in places

where you wouldn’t dream of sending other microcontrollers.

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 an 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.
