Stellaris® LM4F232 Evaluation Kit User’s Manual
Functional Description
Microcontroller, USB OTG, User/Navigation Switches, User LED, and
GPIO Headers (Schematic page 1)
Microcontroller
The Stellaris LM4F232H5QD is an ARM® Cortex™-M4F-based microcontroller with 256-KB Flash
memory, 32-KB SRAM, 80-MHz operation, USB Host/Device/OTG, Hibernation module, and a
wide range of other peripherals. See the LM4F232H5QD microcontroller data sheet (order number
DS-LM4F232H5QD) for complete device details.
Most of the microcontroller signals are routed to 0.1" pitch break-out pads and labeled with their
GPIO reference. An internal multiplexer allows different peripheral functions to be assigned to
each of these GPIO pads. When adding external circuitry, consideration should be given to the
additional load on the evaluation board’s power rails.
The LM4F232H5QD microcontroller is factory-programmed with a quickstart demo program. The
quickstart program resides in on-chip Flash memory and runs each time power is applied, unless
the quickstart application has been replaced with a user program.
USB Host/Device/OTG
The EK-LM4F232 includes a USB Micro-AB (OTG) connector to allow for USB Host, Device, and
OTG operation. The following signals are used for USB OTG.

In USB Host mode, the evaluation board can provide power to the OTG connector. The USB0EPEN
signal controls the Channel 2 Enable (EN2) of a Texas Instruments’ TPS2052B Load Switch (U7)
which enables power to the connector's VBUS pin. The POWER SELECT jumper must be in the
“ICDI” position.
In Device mode, the evaluation board can be powered from either the Stellaris® ICDI or the OTG
connectors. The user can select the power source by moving the POWER SELECT jumper to the
appropriate position.
In OTG mode, the POWER SELECT jumper's position needs special consideration depending on
the system and code configuration.

All unused pins on the microcontroller as routed out to 0.1" headers along the edges of the board
and are conveniently labeled with their port and pin names.
The remaining pins are broken out to headers located near the hardware feature that uses them.
These are also on a 0.1" grid. All of these headers are labeled with the port and pin name, and,
where possible, labeled with their function.See “Schematics” on page 22 for detailed information
on these signals.
Data Logger, Accelerometer, Temperature Sensor, OLED, and SD Card
(Schematic page 2)
Data Logger
The EK-LM4F232 comes with a quickstart application loaded into the Flash memory. This
application implements a multi-channel data logger which can measure up to four analog channels
(0-20 V), a three-axis analog accelerometer, two analog temperature sensors, and the
microcontroller running current.
A Windows quickstart companion application is also provided on the evaluation kit CD and serves
as a secondary display for the Data Logger application. See the “Software Description” on page 20
for more information.
4-Channel Analog Measurement
A 6-position screw terminal block is included on the evaluation board to make easy connections to
external signals. Table 2-3 shows how the screw terminals and channels are arranged.

Each of the 4 channels can measure 0-20 V with an approximate 0.01 V resolution. A voltage
divider on each channel scales the 0-20 V range on the terminal to the 0-3 V range of the 12-bit
Analog-to-Digital Converter (ADC) of the LM4F232H5QD microcontroller. Each scaled-down
signal passes through a unity-gain amplifier to provide a low-impedance source for the
microcontroller’s ADC. Below are some useful equations to keep on hand when using the four data
logger channels.

Caution – Exceeding the input range on either the screw terminal or the ADC pins directly can
damage the analog circuitry.
3-Axis Analog Accelerometer
The evaluation board includes a Bosch BMA140 3-axis analog accelerometer. The accelerometer
is powered by a Texas Instruments’ REF5030 Precision 3.0 V Reference (U9) and outputs an
analog signal centered on half the 3.0 V source; therefore, 0 g translates to 1.5 V on the output.
The sensor can measure accelerations up to ±4 g.

September 14, 2012
Hardware Description
Each axis has its own analog signal; AX, AY, and AZ. The sensor outputs are passed through a
unity-gain amplifier to provide a low-impedance source for the microcontroller’s ADC. Table 2-4
shows which microcontroller pins are used for the accelerometer,

See the Bosch Sensortec Triaxial, Analog Acceleration Sensor Data Sheet (BMA140) for more
information about the accelerometer.
Temperature Sensors
Temperature can be measured by the Texas Instruments’ TMP20 Analog Temperature Sensor
(U3) and/or the internal microcontroller temperature sensor.
External TMP20 Temperature Sensor
The output of the sensor is passed through a unity-gain amplifier to provide a low-impedance

Internal Microcontroller Temperature Sensor
The LM4F232H5QD microcontroller has an internal temperature sensor that can be used to notify
the system that the internal temperature is too high or low for reliable operation. The temperature
sensor can be sampled internally by the ADC. Given the ADC reading, the internal temperature,
T in °C, can be calculated as follows (taken from the LM4F232H5QD data sheet):
T = 147.5 −

See the LM4F232H5QD data sheet for more information on the internal microcontroller

Microcontroller Running Current
The microcontroller running current IDD can be measured by the microcontroller itself. The output
of a Texas Instruments’ INA198 Current Shunt Amplifier (U15) is connected to the ADC on the
microcontroller. This amplifier increases the voltage drop on a 0.1-Ohm current shunt resistor in

Hibernate, Current Shunts, Power Supplies, Reset, and Crystals
(Schematic page 3)
Hibernate
The EK-LM4F232 provides a 32.768 kHz crystal (Y1) as the clock source for the LM4F232H5QD’s
Hibernation module clock source. It also provides a separate 3.0-V CR2032 lithium coin-cell
backup battery connected to VBAT that provides power to the Hibernation module when the
microcontroller is in Hibernate mode. The current draw while in Hibernate mode can be measured
indirectly by measuring the voltage across the 1-kΩ current shunt resistor. See the section,
“Current Shunt Resistors” on page 17 for more details.
Several conditions can generate a wake signal to the Hibernate module; waking on a Real-time
Clock (RTC) match, waking on low battery, and/or waking on assertion of the WAKE pin.1 The
SELECT/WAKE switch is connected to the WAKE pin on the microcontroller. When the
microcontroller is configured to wake on WAKE assertion, the switch can be used to wake the part
from Hibernate mode. The SELECT/WAKE switch is also connected to PM4 by way of a diode to
prevent PM4 from asserting WAKE when the part enters Hibernate mode. See Appendix A,
“Schematics” on page 22 for details.
To achieve the lowest power consumption while in Hibernate mode, the HIB signal is connected to
the Channel 1 Enable (EN1) signal of the Texas Instruments’ TPS2052B load switch (U7). In
Hibernate mode, the HIB signal is asserted and the load switch cuts main power to the entire
board, including the on-board Stellaris ICDI.2 The Hibernation module is powered solely by the
back-up battery.
The EK-LM4F232 has additional circuitry that allows the evaluation board to be turned on even
when a battery is not present or when the battery voltage is too low. A Texas Instruments’
TPS3803-01 Voltage Detector (U12) monitors VBAT and produces a VBAT_GOOD signal when the
battery voltage is above 2.1 V. Using standard logic gates and the state of VBAT and VDD, the HIB
signal can be forced high when VBAT is not valid and the microcontroller is not already powered.
With this circuit, a USB-powered board can turn itself on when the back-up battery is either
missing or fully discharged. See Appendix A, “Schematics” on page 22 for more details.
This additional circuitry may not be needed in all applications. For example, a device powered by
one main battery that doubles as the back-up battery does not need this circuit. Or, when using the
Hibernate module in VDD3ON mode, power is cut to the microcontroller internally which eliminates
the need to use HIB to turn off an external supply.
There are many different ways that Hibernate mode can be implemented in an embedded system.
Each implementation requires its own special design considerations.
1. If the board does not turn on when you connect it to a power source, the microcontroller might be in Hibernate mode (depending
on the programmed application). You must satisfy one of the programmed wake conditions and connect the power to bring the
microcontroller out of Hibernate mode and turn on the board.
2. If you remove power to the on-board Stellaris ICDI, the Stellaris ICDI disconnects from the attached PC and your IDE. If you
are debugging an application when the microcontroller enters Hibernate mode, the IDE might exhibit unwanted behaviors due
to the sudden loss of the Stellaris ICDI. If you are using an externally powered debugger, the connection between the debugger
and the PC should not be affected.
Regardless of the debugger setup, the JTAG module in the microcontroller is turned off when the device is in Hibernation mode,
which means the debugger cannot communicate to the target microcontroller. See the LM4F232H5QD data sheet for more
information about the microcontroller’s state in Hibernate mode.

Hardware Description
Current Shunt Resistors
The evaluation board provides two current shunt resistors to measure the microcontroller running
current, IDD, and the Hibernation mode battery current, IBAT. IDD can be measured by the
microcontroller through a Texas Instruments’ INA198 Current Shunt Amplifier (U15). See
“Microcontroller Running Current IDD” on page 17. IBAT must be measured externally.
Microcontroller Running Current IDD
The shunt resistor for IDD, RVDDSHUNT, is 0.1 Ohms and the INA198 amplifier gain is 100 V/V.
Therefore:
I DD =
VVDDSHUNT VVDDSHUNT
=
0 .1
RVDDSHUNT
VADC = VVDDSHUNT × Gain = VVDDSHUNT × 100
Given the ADC measurement, you can calculate IDD:

Or simply, 10 mV per mA.

The shunt resistor for IBAT, RVBATSHUNT, is 1 kOhm.
I BAT =

=

RVBATSHUNT
Or simply, 1 mV per μA.
Clocking
The EK-LM4F232 uses a 16.0-MHz crystal (Y2) to complete the LM4F232H5QD microcontroller's
main internal clock circuit. An internal PLL, configured in software, multiples this clock to higher
frequencies for core and peripheral timing.
The Hibernation module is clocked from an external 32.768 kHz crystal (Y1).
Reset
The RESET signal into the LM4F232H5QD microcontroller connects to the RESET switch and to
the Stellaris® ICDI circuit for a debugger-controlled reset.
External reset is asserted (active low) under any one of these conditions:

Stellaris® LM4F232 Evaluation Kit User’s Manual
The OLED display has special reset timing requirements requiring a dedicated control line from
the microcontroller.
Power Supplies and Jumper
The EK-LM4F232 can be powered from one of two power sources:
Stellaris® ICDI USB cable (default)
USB OTG cable
A moveable jumper shunt on the POWER SELECT headers is used to select one of the two power
sources. Only one source should be selected at a time.
See “USB Host/Device/OTG” on page 10 for the recommended jumper positions for the specific
USB modes.
The evaluation board is designed to provide power to a limited amount of external circuitry.
Table 2-10 shows the board’s power requirements and Table 2-11 shows the board’s breakout
requirements.

Debug and Virtual COM Port (Schematic Page 4)
Stellaris® In-Circuit Debug Interface (ICDI) and Virtual COM Port
The EK-LM4F232 evaluation board comes with an on-board Stellaris® In-Circuit Debug Interface
(ICDI). The Stellaris® ICDI allows for the programming and debug of the LM4F232H5QD using LM
Flash Programmer and/or any of the supported tool chains. Both JTAG and Serial Wire Debug
(SWD) are supported.
NOTE: Although other Stellaris kits support debug out, the EK-LM4F232 evaluation board does
not support this. You can use another Stellaris evaluation kit for debug out.
An external debugger can be connected to the evaluation board through a 2 x 5 fine pitch (0.05”)
ARM JTAG header. When connecting an external debugger, pin 3 of the JTAG header must be tied

Hardware Description
to ground in order for the Stellaris® ICDI to release control of the JTAG signals. The ARM standard
pinout specifies pin 3 as ground, therefore, any standard third-party debugger should work.
Table 2-12 shows the pins used for JTAG and SWD.

Chipcon Wireless Evaluation Module Connector (Schematic Page 5)
These features are not populated on the board. The pads have been laid out on the board for
customers who want to solder the headers to connect a Texas Instruments’ wireless evaluation
module. See Appendix C, “Bill of Materials (BOM)” on page 29 for the orderable part numbers that
can be populated on the pads (J9, J10, Y4, C66, and C67).
Although no wireless software support is provided out of the box, customers and third parties are
encouraged to port existing wireless projects to the EK-LM4F232 evaluation board through the use
of this interface. See the Chipcon Wireless Evaluation Module Connector schematic on page 27
for information on what peripherals are connected to the wireless headers.

Software Development
This chapter provides general information on software development as well as instructions for
Flash memory programming.
Software Description
The software provided with the EK-LM4F232 provides access to all of the peripheral devices
supplied in the design. The StellarisWare® Peripheral Driver Library is used to operate the on-chip
peripherals.
The software includes a set of example applications that use the StellarisWare® Peripheral Driver
Library. These applications demonstrate the capabilities of the LM4F232H5QD microcontroller, as
well as provide a starting point for the development of the final application for use on the
EK-LM4F232 evaluation board.
The EK-LM4F232 Evaluation Kit CD also contains a Windows quickstart companion for the Data
Logger quickstart application. The companion application provides a strip-chart display for up to 10
channels of data from the EK-LM4F232 evaluation board. You can enable or disable the display for
each channel and log the data to a comma-separated values (CSV) file.
Source Code
The complete source code is included on the EK-LM4F232 CD including the source code for the
Windows quickstart companion application. See the README First document for a detailed
description of hardware setup and how to install the source code. The source code and binary files
are installed in the StellarisWare® software tree.
Tool Options
The source code installation includes directories containing projects and/or makefiles for the
following tool-chains:
Keil ARM RealView® Microcontroller Development System
IAR Embedded Workbench for ARM
Sourcery CodeBench
Code Red Technology Red Suite
Generic Gnu C compiler
Texas Instruments' Code Composer Studio™ IDE
Download evaluation versions of these tools from www.ti.com/stellaris. Due to code size
restrictions, the evaluation tools may not build all example programs. A full license is necessary to
re-build or debug all examples.
Instructions on installing and using each of the evaluation tools can be found in the Quickstart
guides (for example, Quickstart-Keil, Quickstart-IAR) which are available for download from the
evaluation kit section of our web site at www.ti.com/stellaris.
For detailed information on using the tools, see the documentation included in the tool chain
installation or visit the web site of the tools supplier.

Software Development
Programming the EK-LM4F232 Board
The EK-LM4F232 software package includes pre-built binaries for each of the example
applications. If you installed the StellarisWare® software to the default installation path of
C:/StellarisWare, you can find the example applications in “C:/StellarisWare/boards/ek-lm4f232”.
The on-board Stellaris ICDI is used with the Stellaris LM Flash Programmer tool to program
applications on the EK-LM4F232 board.
Follow these steps to program example applications into the EK-LM4F232 evaluation board using
the Stellaris® ICDI:
1. Install LM Flash Programmer on a Windows PC.
2. Connect the USB-A cable plug to an available port on the PC and the Mini-B plug to the board.
3. Verify that the POWER LED D4 on the board is lit.
4. Run LM Flash Programmer.
5. In the Configuration tab, use the Quick Set control to select the EK-LM4F232 evaluation
board.
6. Move to the Program tab and click the Browse button. Navigate to the example applications
directory (the default location is “C:/StellarisWare/boards/ek-lm4f232/”).
7. Each example application has its own directory. Navigate to the example directory that you
want to load and then into the directory which contains the binary (*.bin) files. Select the binary
file and click Open.
8. Set the “Erase Method” to “Erase Necessary Pages,” check the “Verify After Program” box,
and check “Reset MCU After Program”.
9. Click the Program button to start the Erase, Download, and Verify process. The DEBUG
ACTIVE LED (D5) on the board turns on at this time.
Program execution starts once the Verify process is complete.
