EVALUATION KIT AVAILABLE MAX32650MAX32652 Ultra-Low-Power Arm Cortex-M4 with FPU-Based Microcontroller (MCU) with 3MB Flash and 1MB SRAM General Description Benefits and Features DARWIN is a new breed of low-power microcontrollers Ultra-Efficient Microcontroller for Battery-Powered built to thrive in the rapidly evolving Internet of Things (IoT). Applications They are smart, with the biggest memories in their class 120MHz Arm Cortex-M4 with FPU and a massively scalable memory architecture. They run SmartDMA Provides Background Memory Transfers forever, thanks to wearable-grade power technology. They with Programmable Data Processing 120MHz High-Speed and 40MHz Low-Power are also tough enough to withstand the most advanced cyberattacks. DARWIN microcontrollers are designed Oscillators 7.3728MHz Low-Power Oscillators to run any application imaginablein places where you would not dream of sending other microcontrollers. 32.768kHz and RTC Clock (Requires External Crystal) 8kHz Always-On Ultra-Low Power Oscillator Generation UP microcontrollers are designed to handle 3MB Internal Flash, 1MB Internal SRAM the increasingly complex applications demanded by 104W/MHz Executing from Cache at 1.1V todays advanced battery-powered devices and wireless Five Low Power Modes: Active, Sleep, Background, sensors. The MAX32650MAX32652 are ultra-low power Deep-Sleep, and Backup memory-scalable microcontrollers designed specifically 1.8V and 3.3V I/O with No Level Translators for high-performance, battery-powered applications. They Scalable Cached External Memory Interfaces: are based on Arm Cortex-M4 with FPU CPU with 3MB 120MB/s HyperBus/Xccela DDR Interface flash and 1MB SRAM. Memory scalability is supported SPIXF/SPIXR for External Flash/RAM Expansion with multiple memory-expansion interfaces, including a 240Mbps SDHC/eMMC/SDIO/microSD Interface HyperBus/Xccela DDR interface and two SPI exe- cute in place (SPIX) interfaces. A secure digital interface Optimal Peripheral Mix Provides Platform Scalability supports external high-speed memory cards, including 16-Channel DMA SD, SDIO, MMC, SDHC, and microSD. Three SPI Master (60MHz)/Slave (48MHz) One QuadSPI Master (60MHz)/Slave (48MHz) Power management features provide five low power modes Up to Three 4Mbaud UARTs with Flow Control for clock, peripheral, and voltage control. Individual SRAM 2 Two 1MHz I C Master/Slave banks of 32KB, 96KB, or 1024KB (full retention) can be 2 I S Slave retained with reduced power consumption. A SmartDMA Four-Channel 7.8ksps 10-Bit Delta-Sigma ADC performs complex background processing while the CPU USB 2.0 Hi-Speed Device Interface with PHY is off to dramatically reduces overall power consumption. 16 Pulse Train Generators The MAX32651 is a secure version with a trust protection Six 32-Bit Timers with 8mA High Drive unit (TPU) that provides a modular arithmetic accelerator 1-Wire Master (MAA) for fast ECDSA, an AES engine, TRNG, SHA-256 Trust Protection Unit (TPU) for IP/Data Security hash, and secure bootloader. A memory decryption integ- Modular Arithmetic Accelerator (MAA), rity unit (MDIU) provides on-the-fly data decryption (plain True Random Number Generator (TRNG) or executable) stored in external flash. Secure Nonvolatile Key Storage, SHA-256, The MAX32652 is a high-density, 0.35mm pitch, 140- AES-128/192/256 bump WLP package targeted for tiny form factor products Memory Decryption Integrity Unit, Secure Boot ROM that require high I/O counts.
