User manual
Getting Started with the ARMIC30 Evaluation Board
(ARM Core-based Industrial Controller using STR730 MCU)
Introduction
This user manual describes the implementation of the ARMIC30 Evaluation Board. The
ARMIC30 can be used to evaluate a variety of devices, especially microcontrollers, with the
added advantage that all pins are available on logically structured and well-documented
header pins.
Applications are based on 32-bit STR730F microcontroller that uses a powerful ARM7TDMI
core providing an extensive range of peripheral functions and enhanced I/O capabilities.
The ARMIC30 is equipped with RS-232, RS-485, CAN, SPI, I²C and JTAG communication
interfaces.
The evaluation board also includes digital input/output connectors and three motor control
connectors with a pinout compatible with PowerSpin evaluation boards (supporting L6205,
-6, -7, -8, and L6235 integrated motor drivers). The output interface is compatible with
VN808 and VN340 Reference Design Boards and the input interface can be used for CLT3-
4BT6 or PCLT-2A evaluation board connections.
Applications can be supplied from a standard DC power supply (7 to 30V DC) or directly
using a 24V DC industrial mains supply.
Complete solution is implemented on double-face board with only two copper layers for
increased cost-effectiveness. Routing accuracy is also cost-optimized.
The ARMIC30 evaluation board package includes a CD-ROM containing the standard
STR730 software library, source code examples, board fabrication data (Gerber files), this
user manual and other related documentation.

(IC) applications that use several different communication interfaces as shown in Figure 1.
Figure 1. ARMIC30 Communication interfaces
The ARMIC30 comes on a double-face printed circuit board with only two copper layers.
Circuit routing is Class 5 accuracy meaning that the smallest route/isolation distance is 8 mil
(0.2032 mm) and the smallest hole diameter is 20 mil (0.5080 mm). Board dimensions are
132 x 116 mm.

1.1 RS-232 interface
The ST202E Transceiver ensures RS-232 communication through the UART0 serial
channel of the STR730F microcontroller as shown in Figure 4.
The maximum speed of this interface is 230 Kbps.
The UART0 channel can be used for simple communication and internal Flash memory
programming (for example, when using the RFLASHER application from Raisonance).
A male, 9-pin D-Sub connector (J8) provides the RS-232 connection. For correct
interconnection with a PC, a “null-modem” cable (crossed Rx | Tx signals) should be used.
Jumper 35 can be used to select Loop mode (for testing purposes) as described in
Appendix C: Jumper settings.

1.2 RS-485 interface
The ST485A Transceiver ensures RS-485 communication through the UART1 serial
channel of the STR730F microcontroller as shown in Figure 5.
The maximum speed of this interface is greater than 30 Mbps.
A female, 9-pin D-Sub connector (J12) provides the RS-485 connection using a standard
Profibus pinout.
The RS-485 channel can be terminated using jumpers J10 and J13 as described in
Appendix C: Jumper settings. Terminating resistors R25, R26 and R28 are selected for a
Type-A Profibus DP cable as shown in Figure 5. These resistors can be replaced with
different values depending on the physical layer implemented.

1.3 CAN interface
The L9616 High-Speed Transceiver provides the Controller Area Network (CAN)
communication interface through the CAN0 channel of the STR730F microcontroller.
This serial communication can reach speeds up to 1Mbps.
A male, 9-pin D-Sub connector (J15) provides the CAN connection. The CAN channel can
be terminated with a 120Ω resistor using jumper J14 as described in Appendix C: Jumper
settings. The L9616 CAN transceiver has an Adjustable Slope Control (ASC) feature that
sets the slope speed using its ASC pin. This pin can be either hard-connected high or low
using zero-ohm resistors or it can be controlled by MCU Port 2.0 as shown in Figure 6.
Table 4 describes the resistor assembly and control pin signal levels for CAN
communications.

Figure 10. JTAG schematic diagram
1.6.1 JTAG supply voltages
A +3.3V DC supply voltage placed on pins 1 and 2 is provided by the DC/DC converter (U6)
reference pin or a separate linear voltage regulator (U7). Please verify the consumption of
any device (for example, converter box) connected to this connector. According to the
device datasheet, the reference pin can deliver a maximum current of 5mA, providing an
accurate voltage level. If the consumption is higher, select the linear voltage regulator (U7)
for the supply connector using jumper J33 as described in Appendix C: Jumper settings.
Certain converter boxes provide a +5V DC supply voltage for the JTAG interface. The new
generation J-link from IAR Systems (the yellow one) provides the supply voltage on pin
number 19. For applications using supplies from the converter box, connect a wire from pin
number 19 of the JTAG (J7) connector to closest +5V DC supply point (for example, J19
right pin). For JTAG communication functions, jumper J32 must be connected and jumper
J33 set to the "lin" position when a +5V DC voltage supply is used.
Caution: Using a supply from a converter box is not recommended for application development or
testing. Accidental short-circuits may damage USB host or converter box circuits.

DC voltage supply using feedback resistors (R37 and R38) as shown in Figure 15. A green
LED (D13) lights up when this supply is present.
An additional +3.3V DC linear voltage regulator (U7) connected in cascade to the DC/DC
converter output can be used to supply the JTAG connector and level converting resistors
with a +3.3V DC supply voltage. Use jumper J33 to select either a DC/DC reference voltage
or a linear regulator as described in Section 1.6.1: JTAG supply voltages and Appendix C:
Jumper settings.
Connectors J30 or J31 provide the ARMIC30 Evaluation Board power supplies. Connector
J30 includes a polarity protection diode and is suitable for use with a standard mains
adapter having an output voltage range between +7 and +30V DC. Connector J31 is
connected directly to the DC/DC converter input which is over-voltage protected by a transil
diode (D8) for a recommended supply voltage range between +6 and +30V DC. The
ARMIC30 Evaluation Board clearly indicates the power supply polarity.

2 Software
The CD-ROM delivered with the ARMIC30 Evaluation Board contains several software
examples demonstrating the use of microcontroller peripheral circuits. These examples use
the standard STR730 software library which is available on www.st.com. Examples are
created using the IAR Embedded Workbench for ARM development tools and appropriate
project files are available on the CD-ROM.
The STR730 microcontroller is delivered pre-programmed with the “GPIO_ARMIC”
example.

1. This value is not accurate and is for information only. MCU peripherals are not initialized and their pins supplied with static
values. Program is running from internal Flash memory, working in an endless loop, performing only a branch instruction.
All microcontroller peripherals are disabled, CMU is on and PLL is on.
2. Power consumption is measured with a 24V DC supply from J31 connector.
