STMicroelectronics EVALKITST7580-1

Overview

EVALKITST7580-1 from STMicroelectronics is a complete demonstration kit for power line communication (PLC) based on the ST7580 narrow-band FSK/PSK system-on-chip, featuring an integrated STM32 microcontroller, ALTAIR900-based 7.5 W wide-input power supply, USB/SPI/I²C/USART/JTAG interfaces, and µ-SD card support for data logging in CENELEC/FCC-compliant PLC node development.

For engineers reviewing the EVALKITST7580-1 datasheet, EVALKITST7580-1 pinout, EVALKITST7580-1 application, or EVALKITST7580-1 equivalent, this kit delivers turnkey validation of ST7580-based two-way AC mains PLC networks with GUI-controlled transceiver parameter tuning, standalone node operation, and interoperability across multiple nodes on shared mains infrastructure.

Technical Context

The kit implements a point-to-multipoint PLC network using the ST7580 SoC operating in narrow-band FSK/PSK modulation over 3–500 kHz, compliant with CENELEC EN50065 (Europe) and FCC Part 15 (US). It integrates line coupling circuitry, analog front-end filtering, and digital baseband processing on the EVALST7580-1 board.

Hosted by an STM32 microcontroller, the system supports real-time configuration of ST7580 registers via USB virtual COM port or SPI, enables firmware updates, and manages µ-SD card I/O for packet capture and replay - all coordinated through Windows GUI software with programmable center frequency, bandwidth, and modulation depth.

FAQ

Does EVALKITST7580-1 include both PLC and power supply hardware?

Yes. The kit contains two boards: EVALST7580-1 (PLC node with ST7580 SoC and STM32 MCU) and EVLALTAIR900-M1 (7.5 W quasi-resonant SMPS power supply based on ALTAIR04-900). Both are required for full operation and ship together as one unit.

Is the Windows GUI software included with the kit?

Yes. The ST7580 GUI software is provided on the included µ-SD card and supports real-time configuration of modulation parameters, spectrum visualization, packet transmission/reception, and multi-node network diagnostics without additional licensing.

Can EVALKITST7580-1 operate as a standalone PLC node without a PC?

Yes. The onboard STM32 microcontroller runs embedded firmware that enables autonomous operation - including periodic packet transmission, line monitoring, and µ-SD logging - independent of host PC connection after initial configuration.

What regulatory standards does this kit help validate against?

EVALKITST7580-1 supports design verification for CENELEC EN50065 (Europe) and FCC Part 15 Subpart B (USA) emissions and immunity requirements, with pre-characterized analog front-end filtering and line coupling optimized for compliance testing.
