Part of the Darwin product family from Maxim Integrated Products (which is owned by Analog Devices), the MAX32672 is an ultra low-power, cost-effective, highly integrated and highly reliable 32-bit microcontroller (MCU), 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 featuring a floating-point unit (FPU). The MAX32672 also offers legacy designs and an easy and cost-optimal upgrade path from 8- or 16-bit MCUs.
The device integrates 1 MB of Flash and 200 Kb of SRAM to accommodate application and sensor code. Error correction coding (ECC) is implemented on the entire Flash, RAM and cache to ensure highly 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 organised into two equal-sized physical banks to allow execute-while-write and to facilitate ‘live upgrades’.
Multiple high-speed peripherals, such as 3,4 MHz I2C, 50 MHz SPI and UART, are included to maximise 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 digitisation 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 5 x 5 mm, 40-pin TQFN-EP or 7 x 7 mm, 56-pin TQFN package.
