STMicroelectronics COMET10 | Demoboard EVLKSTCOMET10-1 LCD Module

Description

The EVLKSTCOMET10-1 is a development kit for the STCOMET platform, exploiting the performance capability of the full-feature STCOMET10 device. The STCOMET10 is a single device integrating a flexible power line communication (PLC) modem with a fully embedded analog front end (AFE) and a line driver, a high performance 3-channel metrology function and a Cortex ™ -M4 application core.The kit is made of three modules: the STCOMET main board, the LCD module and the power supply board based on the VIPER26H.With this development kit, it is possible to evaluate a complete single phase smart meter with PLC connectivity. The performance of the metering and application functions could be evaluated along with the PLC transmitting and receiving performance.The PLC line coupling interface is designed to allow the STCOMET device to transmit and receive on the AC mains line using any narrow-band PLC modulation (single carrier orOFDM) up to 500 kHz, mainly for automatic meter reading (AMR) applications.The default configuration of the PLC line coupling targets the G3-PLC (ITU G.9903) and PRIME (ITU G.9904) CENELEC A-band protocol standards. With a few BOM modifications,the STCOMET development kit can be adjusted to fit other narrow-band PLC protocols in CENELEC A-band or FCC band (e. g.: S-FSK IEC61334-5-1, IEEE 1901.2, G3-PLC FCC,METERS AND MORE).If necessary, a specific customer's module can be designed and placed instead of the LCD module, for a different peripherals configuration.As it can be seen from the EVLKSTCOMET10-1 picture, a special effort has been made to create the development kit compact and optimized to fit the size of a real meter.The EVLKSTCOMET10-1 is suitable for the evaluation of the complete STCOMET platform.Featuring the full set STCOMET10 chip, the EVLKSTCOMET10-1 demonstrates at the same time all the functions and performance of the STCOM chips.Please check for the EVLKSTCOMET10-1 hardware documentation, evaluation software and firmware libraries at st.com/powerline.
