STR910-EVAL
evaluation board
Introduction
The STR910 evaluation board (STR910-EVAL) is a complete development platform for the
STMicroelectronic’s ARM®core-based STR91xF. Based on the ARM966ES core, the
STR91xF includes Pre-fetch Queue and Branch cache, full speed USB 2.0 compatible port,
Ethernet 100/10 interface, Embedded MAC, CAN2.0B compliant interface, a 2 Mbyte dual
bank Flash memory, a 96 Kbyte SRAM and many peripherals.
The STR910-EVAL board includes an STR910F microcontroller, pre-loaded demonstration
software and a full range of hardware features to help you evaluate device peripherals (such
as motor control, IrDA, USB, Ethernet, CAN) and develop your own applications. Extension
headers make it possible to easily connect a daughter board or wrapping board for your
specific application.

1 Getting started
Your STR910-EVAL is designed with a full range of hardware features that will help you
rapidly evaluate microcontroller peripherals and develop your own applications. Descriptions
of hardware features and configurations are provided in Section 2 on page 8.
Demonstration software is preloaded in the board’s flash memory for easy demonstration of
device peripherals in stand-alone mode. For more information refer to the demonstration
software getting started.
Your STR910-EVAL is also designed for use as an application development platform and
reference design, and supports connection to a full range of in-circuit debugging tools and
integrated development environments.
To start using your STR910-EVAL evaluation board for application development, you will
have to set up your development tools and connect to the STR91xF.
1. Connect to your STR910-EVAL via the 20-pin JTAG connector.
A 38-pin ETM connector is also provided, allowing you to connect to and use your
microcontroller’s Embedded Trace Macrocell during debugging. For additional
configuration information, see Section 2.12 on page 17
2. Power up the evaluation board.
The board can be powered by 5V from either the jack for external power supply, USB
connector, or a daughter board. For additional configuration information, see
Section 2.1 on page 10.
3. Connect to the device from the debugging software on your host PC.
The BCD files, FME file and installation instructions that you will need to update your
debugging software are available for free download at the STMicroelectronics
microcontrollers support site on www.st.com.

2 Hardware layout and configuration
The STR910-EVAL is designed around the STR912FAW47X6 ARM966E-S in 128-pin LQFP
package. The hardware block diagram of the STR910-EVAL (Figure 2) illustrates the layout
of the board relative to the STR91xF peripherals and Figure 4 will help you locate these
features on the actual evaluation board.
Figure 3. Hardware block diagram
Peripheral implementation on the STR910-EVAL board requires the use of alternate pin
functions supported by the STR912FAW47X6. A table of alternate pin functions used in this
design is provided in Appendix A.

The following sections provide jumper settings for configuring your STR910-EVAL
evaluation board and peripherals, including:
Two types of jumpers are used on the STR910-EVAL evaluation board:
●3-pin jumpers with two possible positions, for which settings are presented in
schematics in the following sections
●2-pin jumpers with two possible settings: Fitted– the circuit is closed, and Not fitted–
the circuit is open (see Figure 5)
Figure 5. Settings for two-pin jumpers
2.1 Power supply
STR910-EVAL evaluation board is designed to be powered by a 5V DC power supply. It is
possible to configure the evaluation board to use any of the following three sources for the
power supply:
●5V DC power adapter connected to the power supply jack (CN2, or PSU for Power
Supply Unit on the silk screen).
●5V DC power with 500mA limitation via the USB type-B connector (CN3, or USB on
the silk screen).
●5V DC power from the daughter board extension connectors (CN5 and CN6, DTB
for Daughter Board on the silk-screen).
There is also a 3V button battery, which can be used as a backup power supply for both the
RTC and the internal RAM of the STR91xF microcontroller.
The power supply is configured by setting the related jumpers, JP2, JP3, JP4, JP6 and
JP15 as described in Table 1.
