GENERAL DESCRIPTION
The ZON™ M3S/M3SL and P3S/P3SL (MAX71315C/ MAX71314C and MAX71335C/MAX71334C) integrate dual 32-bit processors and security engines for demanding single phase (MAX71315C/MAX71314C) and poly-phase (MAX71335C/MAX71334C) metering applications with up to 256KB flash, 21KB 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 fixed-point processor dedicated to computing 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 communications. Integrated 38kHz encoding and decoding functions saves BOM cost and reduces board space. Two touch switch pins enable capacitive touch detection. The device family also integrates all the essential metering function blocks: LCD controller supporting up to 8 common planes with a maximum of 288 segments, real-time-clock (RTC) with automatic temperature compensation, and multiple serial communication ports (UART, I2C, and SPI).
