In the Darwin family, the MAX32670/MAX32671 are ultra- low power, cost-effective, high reliability 32-bit microcon- trollers enabling designs with complex sensor processing without compromising battery life. They combine a flexible and versatile power management unit with the powerful Arm® Cortex®-M4 processor with floating point unit (FPU). The MAX32670/MAX32671 also offer legacy de- signs an easy and cost optimal upgrade path from 8- or 16-bit microcontrollers.
The devices integrate 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 bandwidth. In addition, a low-power UART is available for operation in the lowest power sleep modes to facilitate wakeup on 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 PWM generation even in the lowest power sleep modes. The devices pack all this capability in tiny form factors: 5mm x 5mm 40-pin TQFN-EP and 1.842mm x 2.670mm 24-bump WLP packages.
