STMicroelectronics STEVAL-IPE010V2

Overview

STEVAL-IPE010V2 from STMicroelectronics is an energy meter demonstration kit motherboard designed to evaluate the STPMC1 metrology ASSP and interface with up to five STPMS2L-based daughterboards (STEVAL-IPE014V1) for multi-phase voltage/current sensing. It supports 230 VRMS nominal input, CT/shunt current sensing (1 A/5 A nominal), 50/60 Hz line frequency, and operates from –40 °C to +85 °C.

For engineers reviewing the STEVAL-IPE010V2 datasheet, STEVAL-IPE010V2 pinout, STEVAL-IPE010V2 application, or STEVAL-IPE010V2 equivalent, this board serves as a Class 1-compliant evaluation platform for delta/wye 2–4 wire electricity meters with sigma-delta stream aggregation, programmable clock distribution, and microprocessor interface capability via 10-pin flat cable.

Technical Context

The STEVAL-IPE010V2 functions as the central processing and synchronization hub in a modular energy meter architecture: it hosts the STPMC1 ASSP, which receives sigma-delta bitstreams from up to five STPMS2L daughterboards, applies metrology computation, and distributes a programmable-frequency clock (derived from a 4.194 MHz crystal) to each daughterboard.

Dedicated anti-aliasing and crosstalk-reduction networks isolate voltage and current signal paths per phase; on-board stepper motor connectors enable mechanical register drive, while the 10-pin flat cable interface provides access to digital outputs (e.g., pulse, UART, SPI) for firmware integration with host microcontrollers.

Key Specifications

Manufacturer

STMicroelectronics is a global semiconductor leader headquartered in Geneva, Switzerland, designing and manufacturing microcontrollers, power ICs, sensors, and analog/mixed-signal solutions for industrial, automotive, and consumer applications.

The STEVAL-IPE010V2 belongs to ST's Smart Energy Evaluation Platform product line, engineered to accelerate Class 1 and Class 0.5S electricity meter design by decoupling metrology sensing (daughterboards) from computation and communication (motherboard).

FAQ

What daughterboards are required to operate the STEVAL-IPE010V2?

The STEVAL-IPE010V2 requires one or more STEVAL-IPE014V1 daughterboards-each hosting an STPMS2L ASSP-to provide phase voltage/current sensing. Up to five can be connected simultaneously for 3-phase + neutral or 4-wire wye configurations. No daughterboard is pre-mounted; all must be ordered separately.

Does the STEVAL-IPE010V2 include a built-in microcontroller or communication interface?

No. The motherboard does not contain a microcontroller. It interfaces with external host processors via a 10-pin flat cable connector supporting pulse output, UART, and SPI signals. Communication functionality (e.g., PLC, RF, optical port) must be implemented on the connected microprocessor board.

Can the STEVAL-IPE010V2 be used for Class 0.5S meter certification?

It is designed for Class 1 evaluation per IEC 62053-21. While its architecture (STPMC1 + STPMS2L + noise-reduction networks) supports high-precision metrology, Class 0.5S compliance requires additional calibration, layout optimization, and full-system validation beyond the base board's capabilities.

Is the 4.194 MHz crystal oscillator user-replaceable?

Yes-the 4.194 MHz crystal is mounted in a standard SMD package (e.g., HC-49/US) and can be replaced to adjust system timing or accommodate alternative clock sources, though doing so may affect STPMC1 synchronization and sigma-delta sampling alignment with STPMS2L devices.
