   产品概述 返回TOPsaU嘉泰姆

The CXEP2343S 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  CXEP2340 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.
