MAX32670-xx-ARDZ Development Platform Features
The MAX32670-xx-ARDZ Development Platforms feature the MAX32670 high-reliability, ultra-low-power microcontroller based on the Arm Cortex-M4 processor. Let’s explore some of its notable features:
High-Performance Microcontroller Core
The MAX32670-xx-ARDZ platforms are equipped with an Arm Cortex-M4 core featuring a floating-point unit (FPU) capable of operating at frequencies up to 100MHz. The MCU features 384kB of flash memory with error correction and 160kB of SRAM (128kB with ECC enabled), which can be optionally preserved in the lowest power modes. Additionally, the compatible real-time clock (RTC) offers precise resolution for managing protocol timeouts. The platform’s architecture is designed to support complex applications, particularly those requiring high reliability and low power consumption.
Advanced Security Features
Security is a key focus of the MAX32670-xx-ARDZ Development Platform. To ensure data integrity and confidentiality, the platform incorporates secure boot capabilities and supports various cryptographic algorithms, including AES-128/192/256. These features make it suitable for applications where data security is paramount, such as IoT and asset tracking systems.
Radio Front-End (MAX32670-LR-ARDZ only)
The MAX32670-LR-ARDZ platform specifically includes a multi-purpose radio front-end designed for geolocation purposes. This front-end supports Global Navigation Satellite System (GNSS) scanning, including GPS and BeiDou. It also enables ultra-low power passive scanning for 802.11b/g/n Wi-Fi networks.
Long-Range Multi-Protocol Radio Capabilities
Both the MAX32670-SX-ARDZ and MAX32670-LR-ARDZ platforms feature a long-range radio capable of supporting various modulation schemes. These include FSK, GFSK, MSK, GMSK, and long-range FHSS. The radio offers a programmable bit rate of up to 62.5kbps and 300kbps and operates within the sub-GHz ISM bands from 800MHz to 960MHz. This provides a high sensitivity down to -148dBm and a peak transmit power output of +15dBm.
Ultra-Low Power Management
The MAX32670-xx-ARDZ Development Platforms are optimized for energy efficiency, making them ideal for battery-powered devices. To enhance battery life, the platforms incorporate an ultra-low power real-time clock with an integrated power switch. This RTC consumes only 300nA of power during sleep mode, ensuring accurate timekeeping and protocol management while minimizing energy consumption.
