EVALSPEAr320PLC evaluation board for the SPEAr320
Introduction
This user manual describes the implementation of the SPEAr320PLC evaluation board
(order code: EVALSPEAr320PLC). This evaluation board can be used to evaluate the
SPEAr320 microprocessor with a variety of devices and especially its Media Independent
Interface (MII) Automation mode.
The EVALSPEAr320PLC evaluation board kit comprises two boards:
●
CPU board
●
MII mode application board
The SPEAr320 microprocessor is mounted on the CPU board that is plugged on the MII
mode application board.
The application board is equipped with two Ethernet, three RS-232, one RS-485, two CAN,
SPI, I²C communication interfaces and MicroSD card socket with SDIO interface. There are
also two general-purpose push-buttons, four LEDs, a temperature sensor and a
potentiometer available for the user interface.
The application board also includes digital input/output serial/parallel connectors with a
pinout compatible to many existing evaluation boards from ST:
●
Digital input serial: STEVAL-IFP007V1
●
Digital input parallel: STEVAL-IFP004V1 and STEVAL-IFP008V1
●
Digital output serial: STEVAL-IFP009V1
●
Digital output parallel: STEVAL-IFP002V1, STEVAL-IFP001V1 and STEVAL-IFP006V1
The application board can be powered using a standard DC power supply (7 V to 30 V DC)
or directly using a 24 V DC industrial mains supply.
