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 a floating point unit (FPU). It also offers legacy designs an easy and cost-optimal upgrade path from 8- or 16-bit microcontrollers.
The device integrates 384KB (376KB user) of flash memory and 160KB of SRAM to accommodate application and sensor code. 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/power-up events and unexpected supply transients.
Multiple high-speed peripherals such as 3.4MHz I2C, 50MHz SPI, and UARTs maximize communication bandwidth. In addition, a low-power UART is available for operation in the lowest-power sleep modes to facilitate wake-up 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 in the lowest-power sleep modes. All of this capability is packaged in a tiny form factor: 5mm × 5mm, 40-pin TQFN-EP or 1.75mm × 2.50mm, 24-bump WLP.
Applications
