P3SX

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 Compute Engine, CE) is a 32-bit processor dedicated to computing 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 communications. One touch switch pin enables capacitive touch detection. The SY7T166GH (future product) poly-phase metering SoC provides exceptional temperature stability due to dual temperature trim of the bandgap reference. The device family also integrates all the essential metering function blocks: Real-time-clock (RTC) with automatic temperature compensation and multiple serial communication ports (UART, I2C, and SPI). The compact 68-pin QFN package eliminates LCD common pins (LCD segment driver functionality is maintained at certain pins along with GPIO and special functions).
