Maxim 'MAX32630, MAX32631'•••Space-saving, accelerated processing speed, extended battery life

Maxim Integrated Korea (CEO Choi Heon-jeong) announced the ARM Cortex-M4F microcontrollers (MCUs) 'MAX32630' and 'MAX32631', which simplify the design of high-performance medical and fitness wearable devices.

As the market for wellness and medical wearable applications grows rapidly, the requirements for internal electronic components in wearable devices have become more complex and novel. Internal electronic components must provide high levels of functionality, processing power, and optimal integration with peripherals while maintaining a small size. In addition to high precision and low noise, they must exhibit extremely low power loss across various operating modes to ensure sufficient battery life on a single charge. The Maxim MAX32630 and MAX32631 MCUs address these challenges.

The sophisticated power management features of the MAX32630 and MAX32631 maximize operating time. It extends battery life with the industry's lowest energy consumption in full active (127uW/MHz), DMA (32uW/MHz), and retain standby (3.5uW) modes. The onboard code (2MB flash), data (512KB SRAM), and cache (8KB) memory facilitate the execution of third-party applications and the recording of sensor data, thereby enhancing the overall user experience.

The MAX32630 and MAX32631 are powerful processors equipped with a fast Cortex-M4F 32-bit MCU core including an FPU (Floating-Point Unit) in a small form factor of a 4.37mm × 4.37mm 100-ball WLP package. Interfaces include SPI, SPI XIP, UART, I2C, 1-Wire, and USB ports. Peripherals consist of six 32-bit timers, a clock, 66 general-purpose I/O pins, a pulse train engine, and a 10-bit analog-to-digital converter (7.8 ksps).

In particular, the MAX32631 provides customers with a complete security toolbox that protects IP, algorithms, and user data by reinforcing it with a Trust Protection Unit (TPU) that executes intelligent hardware encryption and authentication functions.

Maxim has expanded its portfolio of wearable MCUs featuring a scalable memory architecture with the MAX32630 and the security-enhanced MAX32631. This portfolio consists of the MAX32620 with 2MB of flash memory and 256KB of SRAM, the security-enhanced MAX32621, the security-enhanced MAX32625 with 512KB of flash memory and 160KB of SRAM, and the security-enhanced MAX32626. An evaluation board for the MAX32630 is also available. All products operate in a range from minus 20 degrees Celsius to plus 85 degrees Celsius.

Prem Nayar, Director of Medical & Wearable Micro at Maxim Integrated, stated, “The MAX32630 and MAX32631, designed from the ground up for medical and fitness wearable products, are powerful solutions in ultra-low power, high performance, and small packages,” adding, “The MAX326 MCU family enhances the user experience through sensor integration, flexible design, and connectivity.”
