M3334TIGAE

The NuMicro® M3334TIGAE is a 32-bit microcontroller powered by the Arm® Cortex®-M33 core. It integrates TrustZone technology, a DSP instruction set, and a Floating-Point Unit (FPU). Designed for high-performance applications, it targets industrial control, smart factories, smart buildings, renewable energy, and consumer electronics. Operating at up to 180 MHz, the M3334TIGAE supports 1.7V to 3.6V operating voltage and -40°C to +105°C wide operating temperature. It offers QFN33 package and superior reliability, featuring high immunity with ESD HBM 4 kV and EFT 4.4 kV ratings.
