ST IFW001V1 User Manual
Real-time Ethernet slave node demonstration board
Features
■ 32-bit STR912FAW44 microcontroller with
ARM966E-S™ core running at 96 MHz
■ Two fast E-STE101P Ethernet transceivers
supporting full duplex communication;
available boot configuration settings; up to 32
selectable MII addresses; RJ45 connectors
with embedded LEDs
■ Two 50-pin header connectors for connecting
different on-hook extensions with real-time IP

interface), EMI (external memory interface),
UART, I2C, SPI, external interrupts, 1.8 V, 3.3
V and GND pins
■ Connectors for interfacing with industrial I/O
cards: CAN, AC MC (motor control), CLT/PCLT
(input termination circuit), HSD or SPI HSD
(high side driver)
■ Power supply using the L5973AD DC-DC
converter, and the LF18 for the core supply
■ JTAG debug interface connector
■ 6 V to 30 V DC power supply voltage range
■ One reset and one general-purpose button;
two general purpose LEDs
STEVAL-IFW001V1
based on the STR912FAW44
Data Brief
STEVAL-IFW001V1
For Xilinx® Spartan™ FPGA extensions, refer to
user manual UM0499 for the STEVAL-IFW002V1
demonstration board. With additional on-board
connectors it is possible to connect industrial I/O
cards and motor control boards.
Description
This demonstration board based on
STR912FAW44 was designed for real-time
Ethernet slave communication node evaluation.
This board can be daisy chained with others into
factory automation field bus systems. The board
enables and requires the hooking on of different
extensions that fulfill the requirements for different
real-time Ethernet protocols on the market (e.i.
Powerlink, EtherCAT, and others). For each
protocol a special extension, or a programmable
extension, must be used. The communication
between the board and the extension can be
accomplished through MII, EMI, SPI™, I2C™ or
UART.
