Product description

The MAX32670GTL is an ultra-low power, cost-effective, and highly reliable 32-bit microcontroller that enables complex sensor processing designs without compromising battery life. The device integrates a highly flexible multi-function power management unit with the powerful Arm® Cortex-M4 (with floating point computing unit, FPU). The MAX32670 also provides an easy, cost-optimized way to upgrade traditional designs from 8 - or 16-bit microcontrollers.
