STMicroelectronics STEVAL-IPP003V1

Overview

STEVAL-IPP003V1 from STMicroelectronics is a general-purpose xPSK power line communication (PLC) evaluation module based on the STM32F103RFT6 ARM Cortex-M3 MCU and ST7580 narrow-band PLC modem, supporting up to 28.8 kbps data rate, CENELEC/FCC/ARIP band operation (≤250 kHz), and dual AC/DC bus coupling for metering, building automation, and street lighting applications.

For engineers reviewing the STEVAL-IPP003V1 datasheet, STEVAL-IPP003V1 pinout, STEVAL-IPP003V1 application, or STEVAL-IPP003V1 equivalent, this board provides validated hardware for rapid prototyping of PLC-enabled smart grid endpoints with USB host interface, isolated DC/AC bus connectivity, and field-configurable modulation settings.

Technical Context

The module integrates ST7580 xPSK modem IC with integrated PLM PA, zero-crossing detection, and configurable current-limiting circuitry for robust signal injection into noisy mains environments. It supports dual power supply inputs (USB + external DC or AC bus) and features galvanic isolation between high-voltage mains and low-voltage logic domains via optocouplers and transformer-coupled interfaces.

On-board STM32F103RFT6 provides firmware control over ST7580 registers, UART-based configuration, DFU-capable bootloader, and GPIO-mapped PLC control signals (TX_ON, RX_ON, T_REQ, BR0/BR1). The design allows MCU substitution with STM32F2/F4 series parts via minor assembly changes.

FAQ

What communication protocols does STEVAL-IPP003V1 support out of the box?

The board implements physical-layer xPSK modulation only; higher-layer protocols (e.g., PRIME, G3-PLC, IEEE 1901.2) require custom firmware on the STM32F103RFT6. ST provides basic UART command sets for modem register access and bit-rate configuration, but no built-in MAC or network stack.

Can STEVAL-IPP003V1 operate on 400 VAC three-phase distribution lines?

No - the board is rated for connection to single-phase 230 VAC mains or low-voltage DC buses (≤48 V). Direct connection to 400 VAC requires external step-down/isolation circuitry not included on the board; ST explicitly states it is optimized for CENELEC bands on standard residential/commercial wiring.

Does the ST7580 modem support automatic channel selection or adaptive equalization?

No - the ST7580 operates with fixed-frequency xPSK carriers; channel selection is manually configured via UART commands. It lacks real-time adaptive equalization or spectral sensing; performance relies on pre-characterized filter tuning and external current-limit resistor selection (R21/R19).

Is the USB interface used only for programming, or can it carry PLC data traffic?

USB serves both roles: it enables DFU-based firmware updates and acts as a virtual COM port for bidirectional transmission of raw PLC packets (TX/RX frames) between host PC and ST7580 via STM32 UART bridging - enabling real-time protocol analysis and field-deployable diagnostics.
