1. Overview

1.1 Introduction

The IPC@CHIP® SC23 Embedded Web Controller has been d esigned to meet the most common requirements of embedded products developed for the communication, office automation, mass storage, and general embedded markets. Specific applications would inclu de industrial controls, data collection, protocol conversion, process monitoring and Internet connectivity.

The IPC@CHIP® SC1X3 family is a combination of hardware and software including the preinstalled real-time Operating System, TCP/IP stack, web server, FTP server and Telnet server. It offers increased reliability, functionality and performance, and considerabl y reduced time to market, and also enables designers to reduce the size, power consumption and cost of the embedded system.

The IPC@CHIP® SC23 microcontrollers also integrate the functions of the CPU, two independent timers, watchdog timer, interrupt controller, DMA controller, three asynchronous serial ports, and programmable I/O pins on one chip. It also supports the I²C bus and SPI (Serial Peripheral Interface). The USB interface supports userspecific connections to standard USB hosts like PCs (USB device mode) or memory expansion with USB sticks (USB host mode).

The DB54 development board is designed to provide an easy introduction to the SC23 technology, both for software development in C/C++ and in IEC61131. It also provides a hardware basis for quickly developing a functional prototype for your product. The DB54 can also be expanded ea sily using a plug-in board.

including a breadboard area for customer-specific extensions

4. Electrical Functions / Interfaces

4.1 Power supply

The 24V power supply input of the DB54 is protected against reverse polarity and transient over-voltages. An operating voltage indication (LD1) is located near the power supply socket. Dimming of th e power indication LED signals reset of the SC23. A switching controller from the 9...30V DC power supply of the DB54 is used to provide the internal 3.3V po wer supply. This voltage is also provided at different pin header for external expansions, the 3.3V s witching controll er can supply 600mA for external expansions. In the basic configuration, the maximum internal load of the 3.3V power supply is 400mA. An additional switching controller provides 5V/500mA from the 24V operating voltage of the DB54 for the USB host function.

4.4 SW18 - Power-fail button

Pressing the PFI button (SW18) emulates a power-fail event if the Power-fail function is enabled in the SC23, and calls a power-fail software routine. This routine can write data to the Flash memory area of the SC23. The Powerfail function must be software-enabled (CHIP.INI or software interrupt). Using the PIO9 function of the PFI/PIO9 signal, the PFI button can also be used as a push-button for input.

4.5 SW19 - Reset button

Power-on reset and the reset button (SW19) generate a low active reset pulse for the SC23 processor.

4.6 LED’s and DIP switch

For digital input and output simulation The DIP-switch is connected to an I2C I/O port expander (PCF8574A). It is coded to the I2C base

address 72hex. A switch in the ON position will read out logic 0, and a switch in the OFF position will read out logic 1. Using the I2C port expander it ispossible to have a practical expansion of input and output signals for the SC23.

I/O expander

The LED’s are connected to an I2C I/O port expander (PCF8574A). It is coded t o the I2C base address 70hex. To light up an LED you have to write logic 0 to the correspondi ng port bit, and to switch the LED off you need a logic 1 at the port bit.

A sample program for handling the LED’s and DIP-switch can be obtained from the BECK IPC website.

4.7 LCD Display

For more complex visualization, a two-row, 16 character dot matrix, LCD (without backlight) with KS0066 controller/driver is provided on the DB54. This is an easy way to interface 5V technology and expand the I/O capabilities of the SC23. The LCD is interfaced to an I2C port expander to the SC23 and uses the 4-bit mode. The I2C address of the LCD interface is 74hex. Sample programs for handling the LCD can be obtained from the BECK IPC website.

4.11 S9, S31, S32 - WLAN supporting pin headers

The S9 pin header in conjunction with S31 and S32 supports the usability of the FK61-WL01 WLAN module with the DB54 Board. The FK61-WL01 WLAN module uses the SPI interface at S32 and three PIO pins at S9. To allow WLAN and SD/MMC to coexist at the SPI bus, the WLAN interface uses a different SPI slave select signal (PIO12 / CTS1), so the CTS1 jumper must be removed from S41 for the use of the FK61-WL01 module.

4.19 ST1 - SD/MMC interface

The SD/MMC interface uses the SPI interface of the SC23. As several devices can be connected to the SPI interface, a PIO signal is required as a device-select

signal (SPI slave select, SEL) for each SPI device. The device-select signals are configured via the software. PIO18 is reserved as the device-select signal for the SD/MMC interface on the DB54. The appropriate MMC/SD driver must be installed in order to use the SD/MMC interface. This driver can be obtained from the BECK IPC GmbH website.

4.22 S6 - CAN0 Interface

The CAN0 interface is equipped with a CAN transceiver module and is not isolated. A 120-Oh m terminating resistor (R22) is provided between the CANLOW and CANHIGH si gnal (DSUB 9 female). Additionally it is possible to connect the power supply to pin 9 of the DSUB connector S6 by placing a 0 Ohm resistor at R10. #
