Board Description

The SmartFusion Development Kit Board is designed to pro vide a development platform for users to
evaluate all the features of the world’s only customizable system-on-chip (cSoC) with a hard ARM
Cortex-M3 processor powered microcontroller subsystem (MSS) along with programmable analog.

The board supports a SmartFusion cSoC device in an FG484 package. To enable the MSS, analog, and
evaluation of features, the board includes the following:

• Ethernet, EtherCAT, and USB-to-UART interface for communication with Ethernet and UART
peripherals of the SmartFusion MSS

• Static random access memory (SRAM), parallel flash, SPI flash, and electrically erasable
programmable read-only memory (EEPROM) that interface with EMC, SPI, and I2C peripherals of
the SmartFusion MSS

• Digital-to-analog converter (DAC) that interfaces either to SPI port 0 or SPI port 1 of the
SmartFusion MSS

• Organic light-emitting diode (OLED) that interfaces with either SPI or I
SmartFusion MSS

•I2C interface and temperature monitoring

• Mixed signal header for daughter card interfacing

• RealView ICE Simulation Unit (RVI) header for application programming and debug from either

®

Keil

ULINK® or IAR J-link

The board includes a FlashPro4 programming header to enable programming and debugging from
Microsemi design tools FlashPoint and SoftConsole.

1 – Installation and Settings

Software Installation

Download and install the latest release of Microsemi Libero® Integrated Design Environment (IDE), v9.0
or later, from the Microsemi website and register for your free Gold license. For instructions on how to
install Libero IDE and SoftConsole, refer to the Libero IDE Installation and Licensing Guide, available on
the Microsemi website. Refer to the Installing IP Cores and Drivers User’s Guide for download and
installation of Microsemi DirectCores, SGCores, and Driver firmware cores that must be localized on the
personal computer where Microsemi's Libero IDE is installed when designing with Microsemi FPGAs and
cSoCs. Microsemi has partnered with key industry leaders in the microcontroller space to provide the
robust SmartFusion ecosystem. Microsemi SmartFusion is supported by the latest release of IAR
Systems, the IAR Embedded Workbench for ARM. Refer to Designing SmartFusion with IAR Systems
document for more information. The Microsemi SmartFusion cSoC is also supported by the latest
release of Keil, the MDK-ARM Microcontroller Development Kit. Refer to the Designing SmartFusion with

Keil document for more information.

Hardware Installation

The FlashPro4 (FP4) programmer plugs directly into the A2F500-DEV-KIT-2 board. This allows
programming A2F500 and AGLP125 devices in chain mode or individually with appropriate jumper
settings (JP5).

Jumpers, Switches, LEDs and DIP Switch Settings

The recommended default jumpers, switches, LEDs, and dual in-line package (DIP) switch settings are
shown in Figure 1-1 and defined in Table 1-1 on page 10 through Table 1-4 on page 13. Connect the
jumpers with the default settings to enable the pre-programmed demonstration design to function
correctly.

SmartFusion Development Kit

SmartFusion cSoC Hard ARM Cortex-M3 Processor

The SmartFusion cSoC comes with a hard Cortex-M3 advanced processor-based MSS. The ARM
Cortex-M3 microcontroller is a low power processor that features low gate count, low predictable
interrupt latency, and low-cost debug. It is intended for deeply embedded applications that require fast
interrupt response features. SmartFusion cSoCs use the R1P1 version of the Cortex- M3 processor core.
Some of the important subsystems are listed below:

• Memory protection unit (MPU)

• Single-cycle multiplication and hardware divide

• JTAG debug (4 wire), Serial Wire Debug (SWD – 2 wire) and serial wire viewer (SWV) interfaces

The development board is populated with components to enable development using the MSS. These
components include SRAM, PSRAM, flash, SPI flash, I2C, EEPROM, OLED, SPI DAC, communication
interfaces such as Ethernet, and USB-to-UART.

Revision 7 17

Hardware Components

Power Sources

This board is powered through an external 5 V power supply brick.

SmartFusion Power Sources

Seven voltage rails (10 V, 5 V, 3.3 V, 1.8 V, 1.5 V, and ± 15 V) are provided on the board:

• A single regulator, Linear LT3684EMSE (3.3 V, 2 A), supplies both analog and digital 3.3 V going
to the SmartFusion cSoC device. Sufficient isolation is provided through low-pass filter and layout
to prevent noise from the digital domain to propagate to the analog domain.

• Linear LT3684EMSE (1.8 V, 2 A), supplies 1.8 V rails.

• Linear LT3684EMSE (1.5 V, 2 A), supplies 1.5 V rails.

• Linear LT1615 step-up converter supplies 10 V, 100 mA typical, for driving OLED.

• A single regulator, Linear L T1615, supplies both the +15 V and –15 V with 4 mA rating required by
the DAC comparators.

VAREF Connections

The SmartFusion cSoC has one external VAREF input pin for each of the ADCs. The internal VAREF is
brought out as an output, available as VAREFOUT output pin. There are multiple options available to
drive the VAREF0 and VAREF1 from either external VAREF or the internal VAREF through VAREFOUT
output of the FPGA fabric.

Connect external voltage across J5 pins 1–2 Do not place a jumper on J5

VAREF2 J32: 5–6 Open

Connect external voltage across J6 pins 1–2 Do not place a jumper on J6

Note: You need an external VAREF to monitor voltages greater than 2.56 V on the DC/AC/AT channels. An internal

VREF is sufficient to monitor voltages less than 2.56 V on the ADC/AC/AT channels. All ABPS channels can
monitor voltages greater than 2.56 V using an internal VREF.

Current Sensing Circuit

For applications using the embedded current monitor, a current sensing circuit is provided on the
SmartFusion Development Kit board. The current monitoring is performed across AC0 and AT0 pins of
the SmartFusion cSoC device. The voltage across the potentiometer can be monitored via the AT0 pin.
The current sensing circuits is for the 3.3 V voltage rail as shown in Figure 3-2.

RV1

RV1

Figure 3-2 • Current Sensing

Note: The current monitoring circuit on the SmartFusion Development Kit board is connected to the

SmartFusion cSoC devices CM0 and TM0 inputs. CM0 can also be used to monitor the voltage
across the potentiometer. This input does not have a prescaler circu it. Because of the value chosen
for the potentiometer, the full-scale input is reached after turning the potentiometer about one
quarter of the maximum travel. Although this will not damage the SmartFusion cSoC device, you
may notice the potentiometer is very sensitive.

PWM Circuit

The PWM RC circuit depicted in Figure 3-3 and Figure 3-4 on page 21 can be used with Microsemi
CorePWM instantiated in the FPGA fabric to generate various voltage waveforms. These voltage
waveforms can be displayed on the OLED or used via the mixed signal header. In addition, one PWM RC
circuit source is routed to the AV input pin of an analog quad. This AV pin can be used to monitor the
generated voltage with high accuracy, depending on the ADC resolution configured in the FPGA fabric.

Figure 3-11 • OBD_DACOUT

The OBDs can be used in two applications.
These circuits take the OBD output of the SmartFusion quad and feed it back to the SmartFusion analog

inputs of ADC0 and ADC1 (Table 3-3). This is useful in closed-loop applications.

SmartFusion Development Kit

The OBDs can also be fed into a voltage gain circuit as shown in Figure 3-11 on page 24 and described
in Table 3-4. In this application, the OBD sweep of 0–2.56 V can be translated to –15 V to +15 V. This is
useful in closed-loop applications for ABPS channels with prescalers.

The output of the Opamp can be configured to be monitored by the ABPS channel (Table 3-5). This can
be done as below:

OLED Display

A 9616-pixel low-power OLED is made available on the board for display. This low-power device, WHITE
OLED, requires 3.3 V and 10 V power supplies. Either one of the SmartFusion MSS I2C0 or SPI0 can be
interfaced with the OLED.

The OLED displays sharp gaming images or text. For example, the SmartFusion RTC current time or
time between two events can be displayed on the OLED. Figure 3-12 on page 26 shows the OLED
connections on the board along with jumpers for BS1 and BS2 and the jumper settings for accessing the
OLED from SPI0.
