ZON M3SX/P3SX Single-Phase/Polyphase Electricity Meter SoC General Description The ZON™ M3SX and P3SX (SY7M163G, SY7M166H) integrate dual 32-bit processors and security engines for single-phase (SY7M163G) and poly-phase (SY7M166H/GH) metering applications with up to 256KB flash, 20KB RAM, and a single-cycle 32x32 + 64 multiplier. The application processor (MPU) is a 32-bit MAXQ®30 Core. The metrology processor (or pute Engine, CE) is a 32-bit processor dedicated to puting the metrology 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....
