STMicroelectronics STEVAL-IPE016V1

Overview

STEVAL-IPE016V1 from STMicroelectronics is a single-phase energy metering demonstration board based on the STPM10 metrology IC, achieving Class 0.5 accuracy with 140–300 V_RMS nominal voltage, 2/20 A_RMS current range, and 45–65 Hz line frequency operation. It integrates tamper detection via dual current sensing (CT + shunt), capacitive power supply, and SPI interface for host MCU or PC connectivity.

For engineers reviewing the STEVAL-IPE016V1 datasheet, STEVAL-IPE016V1 pinout, STEVAL-IPE016V1 application, or STEVAL-IPE016V1 equivalent, this board supports rapid validation of residential/utility-grade metering algorithms, tamper-resistant firmware development, and SPI-based energy data acquisition in embedded metering systems.

Technical Context

The board implements a complete single-phase metering signal chain using the STPM10, which performs simultaneous voltage/current sampling, real/active/reactive energy computation, and RMS measurement with on-chip calibration registers. Its tamper detection logic compares live and neutral current paths to identify bypass or neutral disconnection events.

Capacitive power supply enables operation without auxiliary transformer, supporting wide input voltage (140–300 V_RMS) while maintaining stable 3.3 V rail for STPM10 and interface circuitry. The 10-pin header provides direct access to SPI signals (SCLK, MISO, MOSI, CS), reset, and status outputs for system integration.

FAQ

Does STEVAL-IPE016V1 include firmware or software libraries?

No. The board is hardware-only and requires external MCU firmware to read STPM10 registers via SPI. ST provides reference code examples (e.g., AN3479) separately, but no preloaded firmware resides on the board itself.

Can STEVAL-IPE016V1 measure reactive energy?

Yes. The STPM10 IC on board computes active, reactive, and apparent energy simultaneously using dedicated DSP blocks, and all three values are accessible via SPI register reads per ST's STPM10 datasheet.

What is the operating temperature range?

The board is rated for –40 °C to +85 °C ambient operation, matching the STPM10's industrial temperature grade and enabling deployment in outdoor meter enclosures and unconditioned utility environments.

Is RoHS compliance verified and documented?

Yes. The STEVAL-IPE016V1 is explicitly declared RoHS compliant in its official data brief (Doc ID 022628 Rev 1), with full material declarations available through ST's product change notifications and compliance portal.
