MAX71314 Datasheet | Maxim Integrated

MAX71314/MAX71315 EVALUATION KIT AVAILABLE Single-Phase Electricity Meter SOC General Description The MAX71314/MAX71315 integrate dual 32-bit processors for demanding single-phase metering applications with 256k B flash (MAX71315) or 128k B flash (MAX71314), 12k B RAM, and a single-cycle 32 x 32 + 64 multiplier. The user processor (MPU) is a 32-bit MAXQ®30 core. The metrology pute engine (CE) is a 32-bit processor dedicated to puting the metering parameters from voltage and current samples. Features and Benefits - - Four Independent Metrology Channels - - 0.1% Accuracy Over 5000:1 Current Range with Integrated Metrology ADCs - - Two Remote ADC Interfaces - - Support Current Transformers, Rogowski Coils, and Shunts - - Four Pulse Outputs from the CE - - Digital Temperature pensation for Metrology - - 45Hz to 65Hz Line Frequency Range with the Same Calibration - - Phase pensation (±10°) - - 256k B Flash, 12k B SRAM (MAX71315) - - 128k B Flash, 12k B SRAM (MAX71314) For related parts and remended products to use with this part, refer to .maximintegrated./MAX71314.related. - - Single-Cycle 32 x 32 + 64 Multiply-Accumulate Unit - - Low-Power 5ksps ADC for Environmental Monitoring - - RTC with Temperature pensation - - On-Chip Digital Temperature Sensor - - LCD Controller Supporting Up to Eight mon Planes - - Two PWM Relay Control Channels with Programmable Frequency, Duty Cycle, and Ramp Time - - Two Touch Switch Inputs - - 12.5m A Typical Consumption at 3.3V and 10MHz in Active Mode - - 1.75µA Sleep Mode - - SPI (Master and Slave), Master I2C, 4 x UARTs - - Two Smart Card...
