STMicroelectronics STEVAL-IPE003V1

Overview

STEVAL-IPE003V1 from STMicroelectronics is a single-phase electricity meter measurement board featuring 0.5 class accuracy, 140–300 V_RMS nominal voltage, 2/20 A_RMS current range, and tamper detection for power line systems. It supports both standalone operation with stepper motor display and microprocessor-based integration via SPI interface.

For engineers reviewing the STEVAL-IPE003V1 datasheet, STEVAL-IPE003V1 pinout, STEVAL-IPE003V1 application, or STEVAL-IPE003V1 equivalent, this board delivers verified metrology-grade energy measurement with configurable pulse output, capacitive power supply, and LED status indicators for no-load, tamper, reverse energy, and system function.

Technical Context

The board implements ST's analog front-end and metrology IC architecture for single-phase active/reactive/apparent power calculation, RMS voltage/current sensing, and line frequency measurement. It integrates current transformer and shunt-based current sensing paths, enabling dual-path calibration and tamper resilience.

SPI interface provides real-time access to VRMS, IRMS, active/reactive/apparent power, line frequency, and status flags. Stepper motor drive outputs (W5/W6) support mechanical register display, while LVS/KMOT configurators allow user-selectable pulse constant and motor type configuration.

FAQ

What is the primary metrology IC used on STEVAL-IPE003V1?

The board uses ST's dedicated polyphase energy metering IC (e.g., STPM01 or similar generation), configured for single-phase operation with dual current sensing (CT + shunt), on-chip ADCs, and digital signal processing for IEC 62053-21 Class 0.5 compliance. No external MCU is required for basic metering functions.

How is tamper detection implemented on this board?

Tamper detection is implemented through hardware-level monitoring of neutral disconnection, magnetic interference (via optional Hall sensor path), and abnormal current/voltage phase relationships. LED indication for tamper is driven directly by the metrology IC's status output, requiring no firmware intervention.

Can STEVAL-IPE003V1 operate without an external microcontroller?

Yes - in standalone mode, it drives a stepper motor display directly via W5/W6 outputs and provides LED status feedback. Pulse output frequency and motor type are set via onboard LVS/KMOT jumpers, eliminating need for host processor during basic metering and display operation.

What interface options does STEVAL-IPE003V1 provide for host system integration?

The board offers SPI interface via male connector P1 (10-pin), delivering real-time VRMS, IRMS, active/reactive/apparent power, line frequency, and status registers. It does not include UART, I²C, or USB - SPI is the sole digital host interface, optimized for low-latency, deterministic metering data transfer.
