STEVAL-IPP003V1 STMicroelectronics

STEVAL-IPP003V1 General purpose xPSK power line communication module Data brief Description The STEVAL-IPP003V1 evaluation board is a PLM communication module that can be used for a large set of applications, including metering, building automation and street lighting. The module is optimized to operate in CENELEC bands, but can also work in FCC and ARIP bands up to 250 kHz with a few modifications. The module is based on the STM32F103RFT6 ARM Cortex-M3 microcontroller and the ST7580 xPSK narrow band power line modem with up to 28.8 kbps data rate. The MCU mounted on the board can be easily replaced with an equivalent 64-pin MCU from the STM32F2 or STM32F4 Features family by a few modification in the assembly. The module can be coupled to both AC and DC power Insulation from the high voltage mains line buses and also includes a USB interface for Interfaces included: optional PC connection. USB interface Dual DC power supply Digital interface DC or AC insulated bus interface xPSK modulation with bitrate up to 28.8 kbps RoHS compliant December 2013 DocID025671 Rev 1 1/7 For further information contact your local STMicroelectronics sales office. www.st.comSchematic diagram STEVAL-IPP003V1 1 Schematic diagram Figure 1.
