MAX71334C Overview
The application processor (MPU) is a 32-bit MAXQ®30 core. The metrology processor (or pute Engine, CE) is a 32-bit fixed-point processor dedicated to puting the metering parameters from voltage and current samples. The integrated security engines (AES-128/ 192/256, AES-GCM-128, DES, TRNG) provide fast data encryption and decryption for secure smart grid munications.
