In the DARWIN family, the MAX32672 is an ultra-low-power, cost-effective, highly integrated, and highly reliable 32-bit microcontroller enabling designs with complex sensor processing without compromising battery life. It combines a flexible and versatile power management unit with the powerful Arm® Cortex®-M4 processor with a floating-point unit (FPU). The MAX32672 also offers legacy designs an easy and cost-optimal upgrade path from 8- or16-bit microcontrollers.

The device integrates 1MB of flash and 200KB of SRAM to accommodate application and sensor code. Error correction coding (ECC) is implemented on the entire flash, RAM, and cache to ensure extremely reliable code execution even in the harshest of environments. Brownout detection ensures proper operation during power-down and power-up events and unexpected supply transients. The flash is organized into two equal-size physical banks to allow execute-while-write and facilitate "live upgrades."

Multiple high-speed peripherals such as 3.4MHz I2C, 50MHz SPI, and UART are included to maximize communication bandwidth. In addition, a low-power UART (LPUART) is available for operation in the lowest power sleep modes to facilitate wake-up activity without any loss of data. A total of six timers with I/O capability are provided, including two low-power timers to enable pulse counting, capture/compare, and pulse-width modulation (PWM) generation, even in the lowest power sleep modes. An incremental/quadrature encoder interface with multiple diagnostics is included specifically for motor control applications. A 1Msps, 12-channel, 12-bit successive approximation register (SAR) ADC is integrated for the digitization of analog sensor signals or other analog measurements. Two low-power comparators, available in all low-power modes, allow energy-efficient monitoring and wake-up on external analog signals. An Elliptic Curve Digital Signature Algorithm (ECDSA)-based cryptographic secure bootloader is available in ROM. The device is available in a 5mm x 5mm, 40-pin TQFN-EP or 7mm x 7mm, 56-pin TQFN.
