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
G
MII mode application board
G
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
G
Digital input parallel: STEVAL-IFP004V1 and STEVAL-IFP008V1
G
Digital output serial: STEVAL-IFP009V1
G
Digital output parallel: STEVAL-IFP002V1, STEVAL-IFP001V1 and STEVAL-IFP006V1
G
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.

Unpacking Warning: This board contains static sensitive devices. The EVALSPEAr320PLC evaluation board is shipped in protective anti-static packaging. Do not submit the board to high electrostatic potentials, and follow good practices for working with static sensitive devices. Wear an anti-static wristband. Wearing a simple anti-static wristband can help prevent ESD from damaging the board. -
Page 10: Configuration
Configuration UM0842 Configuration Ethernet There are two Ethernet PHYs (U5 and U6) available on the board that are connected through the media independent interfaces (MII) to the Ethernet MACs on the CPU board processor. By default the MII addresses of the Ethernet PHYs are selected as shown in Table Table 1. -
Page 11: Digital Input / Digital Output Connectors
Digital input / digital output connectors The digital input and digital output connectors are used to extend the EVALSPEAR320PLC board with the industrial input and output cards. The input sensors (for example, proximity switches) of the controlled industrial process are normally decoupled and connected by the current limiters based on the CLT and SCLT devices of the microcontroller. -

8/16 input channel current limiter based on SCLT3-8, STEVAL-IFP007V1 Controller–area network bus The EVALSPEAR320PLC evaluation board supports two channels of CAN2.0A/B compliant controller–area network (CAN) bus communication based on a 3.3 V CAN transceiver. High- speed mode, standby mode and slope control mode are available and can be selected by setting jumper JP1 for CAN0 and jumper JP4 for CAN1. -
