STMicroelectronics STEVAL-IPE004V1

Overview

STEVAL-IPE004V1 from STMicroelectronics is a single-phase electricity meter measurement board designed for Class 0.5 accuracy energy metering, 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 temperature, with shunt-based current sensing and LED status indicators.

For engineers reviewing the STEVAL-IPE004V1 datasheet, STEVAL-IPE004V1 pinout, STEVAL-IPE004V1 application, or STEVAL-IPE004V1 equivalent, this board provides verified metrology signal conditioning, SPI-accessible active/reactive/apparent power, VRMS/IRMS/frequency measurements, and tamper-detect-ready interface architecture for standalone or microprocessor-coupled meter designs.

Technical Context

The board implements shunt-based current measurement with dedicated analog front-end circuitry feeding into ST's polyphase metrology IC (e.g., STPM01 or compatible), delivering calibrated RMS voltage/current, fundamental and harmonic power quantities, and line frequency via SPI. It includes capacitive power supply for auxiliary rail generation and discrete LED drivers for real-time functional, no-load, and reverse-energy indication.

Two operational modes are supported: standalone mode using stepper motor display connected at W5/W6 (configurable via LVS/KMOT jumpers), and microprocessor-based mode via 10-pin male connector P1, enabling host MCU control and data readout over SPI with defined register mapping for energy and status registers.

FAQ

Is STEVAL-IPE004V1 still in production?

No. STEVAL-IPE004V1 is marked as obsolete by STMicroelectronics per its January 2006 data brief. It remains available through authorized legacy distributors and Aetrix Electronics' continuity program for existing designs requiring replacement or validation support.

What metrology IC is used on this board?

The board integrates ST's STPM01 or functionally equivalent polyphase metrology IC, confirmed by schematic analysis and ST's documented reference design lineage. It performs simultaneous voltage/current sampling, computes active/reactive/apparent power, and outputs calibrated RMS values via SPI.

Can it operate without a host microcontroller?

Yes. In standalone mode, the board drives a stepper motor display directly via W5/W6 terminals. Jumper settings (LVS/KMOT) configure pulse constant and motor type, enabling mechanical kWh display without external MCU intervention.

Does it support anti-tampering features?

The board provides hardware-level signals and routing for tamper detection-including reverse-energy indication and configurable status flags-but requires external implementation of magnetic, cover-open, or neutral-current monitoring circuits on the host system or companion board.
