User manual
Hardware interconnection of the STM32™,
SPEAr™3xx, and ST75xx
1 Introduction
This user manual describes the STarGrid powerline modem, the latest family of powerline
modems from STMicroelectronics™. The powerline modem itself, although a powerful
device, always needs an external superior system which it uses in order to exchange
information with another node, where another powerline modem and superior system can
be found.
There are various superior systems and this document deals with the hardware
interconnection to powerline modems. These superior systems are from very simple 32-bit
microcontroller boards running standalone firmware to very complex 32-bit micro processor
units running operating systems. This document describes the possible ways of
interconnection and available HW and SW tools for building the system consisting of the
STM32 or SPEAr3xx, and powerline communication coming from the ST7570, 80, and 90
STarGrid family.
The related demonstration boards are:
■STEVAL-PCC012V1
■STM3210C-EVAL
■EVALSPEAr310
■EVALSPEAr320PLC
■EVALSPEAr320HMI
■EVALST7570, 7570-1 KIT, 7580-1, 7590-1.

Figure 14. EVALSPEAr320HMI and ST7570, ST7580, ST7590 via UART
The demonstration boards necessary to connect the EVALSPEAr3xx with the ST7570/80/90
board and their configuration:
1. EVALSPEAr3xx
●Plug Flash disk with correct SW into the first USB, use file system of this USB.
●Interconnect connector CN704 with EVALST75xx unified extension connector
(Ta b l e 6 ) by the flat ribbon cable as shown in Figure 24 and Figure 25. If
additional signals are needed use information from Figure 25.
2. EVALST75xx
●Put the jumper into position JP12 - USB_RES (see paragraph 1
in Appendix C).
