In the Darwin family, the MAX32670 is an ultra-low power, cost-effective, high reliability 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 floating point unit (FPU). The MAX32670 also offers legacy designs an easy and cost optimal upgrade path from 8- or 16-bit microcontrollers.
The device integrates up to 384KB of flash and 160KB of SRAM to accommodate application and sensor code. er­ror correction coding (ECC), capable of single error cor­rection and double error detection (SEC-DED), is imple­mented over the entire flash, RAM, and cache to ensure ultra-reliable code execution for demanding applications. Additional features such as the two windowed watchdog timers with fully flexible and independent clocking have been added to further enhance reliable operation. Brown-out detection ensures proper operation during power-down and power-up events and unexpected supply tran­sients.
Multiple high-speed peripherals such as 3.4MHz I2C, 50MHz SPI, and 4MBAUD UARTs are included to maxi­mize communication bandwi...
