ZON M3SX/P3SX
Single-Phase/Polyphase Electricity
Meter SoC
General Description
The ZON™ M3SX and P3SX (SY7M163G, SY7M166H) in-
tegrate dual 32-bit processors and security engines for sin-
gle-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 volt-
age 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 tem-
perature trim of the bandgap reference.
The device family also integrates all the essential metering
function blocks: Real-time-clock (RTC) with automatic tem-
perature 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 cer-
tain pins along with GPIO and special functions).
Applications
