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.

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.

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.
