Ultra-Low-Power 32-bit MCU Ecosystem

Microchip Ultra-Low-Power 32-bit MCU Ecosystem is a wide selection of ultra-low-power and low-power MCUs providing low power consumption, culminating in less than 35uA/MHz active and 200nA sleep current. The energy-efficient 32-bit MCUs range from the smallest SAMD, to the ultra-low-power SAML, to higher-performing SAMG and PIC32MX XLP MCUs.
