STMicroelectronics STEVAL-IPE002V1

Overview

STEVAL-IPE002V1 from STMicroelectronics is a single-phase electricity meter measurement board certified to Class 0.5 accuracy, supporting 140–300 V_RMS input voltage, 2/20 A_RMS current range, 45–65 Hz line frequency, and operation from –40 °C to +85 °C ambient. It integrates tamper detection, LED status indicators (functioning, no-load, tamper, reverse energy), capacitive power supply, and SPI interface for real-time active/reactive/apparent power, V_RMS, I_RMS, and line frequency reporting.

For engineers reviewing the STEVAL-IPE002V1 datasheet, STEVAL-IPE002V1 pinout, STEVAL-IPE002V1 application, or STEVAL-IPE002V1 equivalent, this board supports both standalone stepper-motor-driven metering and microprocessor-based meter architectures with configurable pulse output and tamper-resilient AC power line monitoring.

Technical Context

The STEVAL-IPE002V1 implements a complete analog front-end for single-phase energy measurement, featuring two current transformers for isolated current sensing and precision voltage scaling circuitry. Its signal chain feeds into an internal ADC and metrology processing path compliant with IEC 62053-21 Class 0.5 requirements.

It provides dual operating modes: standalone mode drives a stepper motor display via W5/W6 outputs with configurable pulse constant (via KMOT) and motor type selection (via LVS); microprocessor mode uses a 10-pin male connector (P1) for SPI communication and control, enabling host MCU integration for advanced metering firmware and data logging.

FAQ

Is STEVAL-IPE002V1 still in production?

No - STEVAL-IPE002V1 is marked as Obsolete by STMicroelectronics per its January 2006 Data Brief. It remains available through authorized legacy distributors and Aetrix Electronics' extended-life inventory program for design continuity and repair support.

What are the two operating modes supported by this board?

The board supports standalone mode (driving a stepper motor display via W5/W6 with configurable pulse constant and motor type) and microprocessor-based mode (SPI-connected to a host MCU via 10-pin P1 connector for full metrology data access and system-level control).

Does STEVAL-IPE002V1 include tamper detection features?

Yes - it implements dedicated tamper detection circuitry for power line systems, with visual indication via a dedicated LED. The board detects anomalies such as magnetic tampering, neutral disconnection, and reverse energy flow per IEC 62053-31 requirements.

Can this board be used without a microcontroller?

Yes - in standalone mode, the board autonomously drives a stepper motor display using on-board metrology logic. No external MCU is required; configuration is performed via hardware jumpers (LVS and KMOT) to select motor type and pulse constant.
