STMicroelectronics STEVAL-IPE010V1

Overview

STEVAL-IPE010V1 from STMicroelectronics is an energy meter demonstration kit motherboard designed to evaluate the STPMC1 metrology ASSP and STPMS1 phase-sensing ASSPs. It supports 2–4 wire delta/wye power line systems, handles 230 VRMS nominal voltage, 1 A/30 A CT current, and 5 A/80 A shunt current, and operates from –40 °C to +85 °C for Class 1 meter development.

For engineers reviewing the STEVAL-IPE010V1 datasheet, STEVAL-IPE010V1 pinout, STEVAL-IPE010V1 application, or STEVAL-IPE010V1 equivalent, key considerations include its role as a reference platform for polyphase energy metering, sigma-delta stream interface between STPMS1 daughterboards and STPMC1, 4.194 MHz crystal-based clock distribution, and 10-pin flat cable interface to host microprocessor boards for tariff management and communication.

Technical Context

The motherboard implements a centralized metrology architecture where the STPMC1 serves as the master processing unit, receiving independent sigma-delta bitstreams from up to five STPMS1-equipped daughterboards (STEVAL-IPE011V1), each monitoring one phase's voltage (via resistive divider) and current (via CT or shunt).

It provides programmable clock generation (derived from a 4.194 MHz crystal) to synchronize all STPMS1 devices, includes dedicated anti-aliasing and crosstalk-reduction networks per channel, and supports stepper motor drive outputs for mechanical register interfacing.

FAQ

What is the function of the 4.194 MHz crystal on the STEVAL-IPE010V1 motherboard?

The 4.194 MHz crystal serves as the master timing reference for the STPMC1, which generates and distributes a programmable system clock to all connected STPMS1 daughterboards. This ensures precise synchronization of sigma-delta modulators across phases, minimizing inter-channel timing skew and preserving metrology accuracy in polyphase measurements.

Can the STEVAL-IPE010V1 operate without daughterboards?

No - the STEVAL-IPE010V1 motherboard requires at least one STEVAL-IPE011V1 daughterboard to provide sigma-delta current/voltage data streams. The STPMC1 has no onboard sensing circuitry; it relies entirely on external STPMS1 devices for raw metrology inputs and autonomous power delivery via the card-edge connector.

Does the kit support both CT and shunt current sensing simultaneously on the same phase?

No - each STEVAL-IPE011V1 daughterboard supports either CT or shunt sensing per phase, selected by hardware configuration (jumper or solder bridge). The motherboard does not enable concurrent dual-sensor operation on a single channel; design choice is fixed per daughterboard during assembly.

What communication interfaces does the STEVAL-IPE010V1 provide for host MCU connectivity?

The motherboard offers only a 10-pin flat cable interface carrying parallel digital signals (including sigma-delta streams, clock, and control lines) - no native UART, SPI, I²C, or USB. External MCU must implement custom firmware to decode sigma-delta data and manage STPMC1 registers; no on-board protocol translation or transceivers are included.
