目录产品概述 返回TOP 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.The ZON™ P5S/P5SL (CXEP2344) and ZON M5S/M5SL (CXEP2344) 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.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.产品特点 返回TOP Low Power Consumption Less Than 5mA (typ) Consumption at 3.3V and 20MHz in Active Mode < 3μA in RTC Compensation Mode, 2.3μA in SLP Mode 2.7V to 3.6V Operating Voltage Advanced AFE with Exceptional Accuracy and Temperature Stability Voltage Reference Temperature Coefficient (max) 40ppm/°C RTC with Dedicated Temperature Compensation Circuit On-Chip Digital Temperature Sensor and Battery Monitor 24-Bit 2nd Order Delta-Digma ADCs with Differential Inputs Supporting CTs, Rogowski Coils and Both Single and Dual Input Remote Sensor Interface SoCs with Shunts ( CXEP2340) Configurable Sampling Rate Up to 10ksps/Channel ±0.1% Wh Accuracy Over 5000:1 Current Range 40Hz–70Hz Line Frequency Range and Phase Compensation (±10°) Highly Integrated Product Features and Flexible Peripherals Support Broad Application Needs Single 32kHz Crystal Provides All Operating Clocks Low-Power 5ksps Auxiliary ADC for Environmental Monitoring Two PWM Control Channels with Programmable Frequency, Duty Cycle, and Ramp Time Two Touch Sensor Switch Inputs SPI and I2C Master and Slave Security Engines (3DES, AES) 5 Timers Single-Cycle 32 x 32 MAC Unit 4x 40/6x 38/8x 36 LCDs with Autopaging 5 UARTs, 1 with 38kHz IR Encoder/Decoder), Two Compliant with ISO 7816 应用范围 返回TOP Energy Monitoring Secure Meters Smart Meters 技术规格书（产品PDF) 返回TOP 需要详细的PDF规格书请扫一扫微信联系我们，还可以获得免费样品以及技术支持！ | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
