MAX71314/MAX71315

Single-Phase Electricity Meter SOC

● Single-Cycle 32 x 32 + 64 Multiply-Accumulate Unit

● Low-Power 5ksps ADC for Environmental Monitoring

● RTC with Temperature Compensation

General Description

The MAX71314/MAX71315 integrate dual 32-bit

processors for demanding single-phase metering appli-

cations with 256kB flash (MAX71315) or 128kB flash

(MAX71314), 12kB RAM, and a single-cycle 32 x 32

+ 64 multiplier. The user processor (MPU) is a 32-bit

● On-Chip Digital Temperature Sensor

● LCD Controller Supporting Up to Eight Common

Planes

MAXQ 30 core. The metrology compute engine (CE) is

a 32-bit processor dedicated to computing the metering

parameters from voltage and current samples.

● Two PWM Relay Control Channels with

Programmable Frequency, Duty Cycle, and Ramp

Time

Features and Beneﬁts

● 12.5mA Typical Consumption at 3.3V and 10MHz in

● 0.1% Accuracy Over 5000:1 Current Range with

Active Mode

Integrated Metrology ADCs

● 1.75µA Sleep Mode

● Two Remote ADC Interfaces

● SPI (Master and Slave), Master I²C, 4 x UARTs

● Two Smart Card Ports

● Support Current Transformers, Rogowski Coils, and

Shunts

● 38kHz IR Encoder/Decoder

● Up to 10 MIPS (at 10MHz)

● 100-Pin LQFP

● Four Pulse Outputs from the CE

● Digital Temperature Compensation for Metrology

● 45Hz to 65Hz Line Frequency Range with the Same

Calibration

● Phase Compensation (±10°)

● 256kB Flash, 12kB SRAM (MAX71315)
