IPC@CHIP DB54

Hardware Manual V1.1 [04.10.2007]

1. Overview

1.1 Introduction

The IPC@CHIP® SC23 Embedded Web Controller has been designed to meet the most common requirements

of embedded products developed for the communication, office automation, mass storage, and general

embedded markets. Specific applications would include 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 considerably 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 user-

specific 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 easily 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 the 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 power

supply. This voltage is also provided at different pin header for external expansions, the 3.3V switching controller

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 Power-

fail 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.

The LED’s are connected to an I2C I/O port expander (PCF8574A). It is coded to the I2C base

address 70hex. To light up an LED you have to write logic 0 to the corresponding 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.
