The ZON™ P5S/P5SL (MAX71336S/MAX71335S) and ZON M5S/M5SL (MAX71316S/MAX71315S) are very low-power poly- and single-phase metering systems-on-chips (SoCs) that comprise a 20MHz MAXQ30 MPU core, realtime clock (RTC) with digital temperature compensation, flash memory, LCD drivers and a single-cycle 32 x 32 multiplier (MAC). Seven (ZON P5S/P5SL) or four (ZON M5S/M5SL) analog inputs with individual 24-bit delta-sigma ADCs, digital metrology temperature compensation, a precision voltage reference, a 32-bit computation engine (CE) with four pulse outputs, and security engines implementing AES and DES encryption support a wide range of smart metering applications with very few external components.
The ZON P5S/P5SL and ZON M5S/M5SL SoCs support optional interfaces to the 71M6xxx and MAX71071 series of isolated remote sensors that offer BOM cost reduction and enhanced reliability. The devices feature low-power operation in active and battery modes, 48KB RAM, and 256KB or 512KB of flash memory, programmable with code and/or data during meter operation.
A complete array of code development tools, demonstration code, and reference designs enable rapid development and certification of meters that meet all ANSI, IEC, and BIS electricity metering standards worldwide.
