Introduction
This user manual describes the implementation of the EVALSP320SPLC evaluation board
(order code: EVALSP320SPLC). This evaluation board can be used to evaluate the
SPEAr320S microprocessor with a variety of devices and especially its Media Independent
Interface (MII) Automation mode.
The EVALSP320SPLC evaluation kit includes a single application board identified as "MII
mode".
The SPEAr320S microprocessor is mounted on a separate CPU board, which is not
included with the EVALSP320SPLC kit. It must be ordered separately with order code
EVALSP320SCPU.
The EVALSP320SCPU board must be plugged on the MII mode application board.
The MII mode 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.
