1.0 Introduction

The point of sale (POS) terminal is an embedded PC platform with custom features designed for a retail and service environment. The major difference between a POS terminal and a normal PC is that a POS terminal is a cost-effective custom design, with unneeded PC features removed.

More and more industries are switching to POS terminals to replace cash registers, causing the market for POS terminal systems to grow enormously. Because POS terminal systems are usually connected to a network and often require a graphical user interface, high performance POS terminal systems are in demand.

The design described in this document was created to reduce the development cycle for point of sale terminal designers. This design provides a head-start in product development which can result in faster time to market.

Caution: The design has not been implemented in hardware. This document is for reference only. Customers are responsible for validating designs created using the information in this document.

1.1 Design Overview

This design is based on the Intel Embedded Processor Module. The processor used in the Embedded Processor Module is either a 133 MHz Intel® Pentium® processor with VRT technology (for the EMBMOD133) or a 166 MHz Intel® Pentium® processor with MMX™ technology (for the EMBMOD166). The EMBMOD133 module is used in this design.

The design closely emulates a PC environment and uses common, standard components. Fserial ports support peripherals, such as barcode scanners, digital scales, card readers and cprice displays. A printer and cash drawer can be connected using the parallel port and a keycan be connected using the PS/2 connector provided in the design.

Designers should check for device availability before designing-in any of the components inclin the document. This document describes the operation of the POS terminal design from a hardware perspective. BIOS and operating system operation is not discussed. The design habeen implemented in hardware.

3.0 POS Terminal Design Details

For more information about the POS terminal design, please refer to the schematics located in Appendix B, “Schematics.”

3.1 Intel Embedded Processor Module (EMBMOD133)

The Embedded Processor Module has two connectors and a heat sink for the Pentium proceThe two connectors carry power, clocks, the DRAM memory interface and the 33 MHz PCI interface. 3 V and 5 V power is provided to the Embedded Processor Module. The module generates the core voltage. This core voltage is provided to the POS terminal baseboard forpower-on sequencing circuitry.

For more information, please refer to the Intel Embedded Processor Module datasheet (order number 273105) and AP-757, Embedded Processor Module Design Guide (order number 273120).

3.2 Intel 82371SB PCI ISA IDE Xcelerator

The Intel 82371SB requests control of the PCI bus by asserting the PHOLD# signal, and becthe PCI master upon receipt of the PHOLDA# signal from the Embedded Processor Module.Intel 82371SB contains the PCI and ISA interrupt controller, along with various ISA legacy functions such as a DMA controller, a bus master IDE Interface, an ISA bus interface, an ISAclock control, an XD bus control, a USB interface and a BIOS ROM interface.

For more information on the Intel 82371SB PCI ISA IDE Xcelerator, please refer to the Intel 82371FB (PIIX) and 82371SB (PIIX3) PCI-TO-ISA/IDE Xcelerator datasheet (order number 290550) and the Intel 82371SB PCI-TO-ISA/IDE Xcelerator (PIIX3) Timing Specification (order number 272963).

3.3 PCMCIA Connector

The PCMCIA connector has three main components:

• PCMCIA host adapter (CL-PD6710)

• PCMCIA connector

• Analog power controller circuit

3.3.1 PCMCIA Host Adapter

The Cirrus Logic PCMCIA host adapter (CL-PD6720) is a single chip capable of controlling two PCMCIA sockets. One PCMCIA socket is implemented in the design. The CL-PD6720 is fully compliant with the PCMCIA (v2.1) and JEIDA (v4.1) specifications and is optimized for use in palmtops and laptops, in which the main design objectives are reduced form-factor and low-power consumption. This chip also provides fully buffered PCMCIA interfaces. No external logic is required for buffering signals to or from the interface, and power consumption can be controlled by limiting signal transitions on the PCMCIA bus.

essive

The chip also supports fully mixed voltage operation, a key feature for low power system design and low-power card operation. The core, ISA interface, and the PCMCIA socket interface can all operate independent of each other at either 3.3 V or 5 V.

The design can support either 3.3 V or 5 V operation and can be switched back and forth between 3.3 V and 5 V operation. Automatic voltage sensing has not been implemented in this design; the correct voltage must be set by the driver.

3.3.2 PCMCIA Voltage Control

The Linear Technology (LTC 1472*) switching matrix routes power to both the +5V (VCC) and +12V (VPP) power supply pins on the individual PC Card sockets. The VCC output of the LTC 1472 is switched between three operating states: OFF, 3.3 V and 5 V. The VPP output is switched between four operating states: 0 V, VCC, 12 V and Hi-Z. The VCC output of the LTC 1472 can supply up to 1 A of current and the VPP output up to 120 mA. Both switches have built-in current limiting and thermal shutdown to protect the card, socket, and power supply against accidental short-circuit conditions.

3.4 Serial and Parallel Communications

COM1 and COM2 are generated and supported by the National Semiconductor 87307 Super I/O device. COM3 and COM4 are generated and controlled by the Exar ST16C452 Dual Asynchronous Receiver/Transmitter with Parallel Printer Port device.

COM3 occupies 03E8 - 03EF and COM4 occupies 02E8 - 02EF in the address range. An additional logic decoding circuit decodes COM3 and COM4 on ST15C452. This is performed by the CSA# and CSB# signals on the UART.

The Exar ST16C452 chip is a dual universal asynchronous receiver and transmitter (UART) with a bidirectional Centronics* compatible parallel printer port. A programmable baud rate generator is provided to select transmit and receive clock rates from 50 Hz to 1.5 MHz.

The ST16C452 on-board status registers indicate the error conditions, type and status of the transfer operation being performed. Additional features include:

• Complete MODEM control capability

• A processor interrupt system that may be software tailored to the user’s requirements

• Internal loop-back capability for on-board diagnostic testing

Connection to the LPT1 parallel port is made using a 25-pin female D-sub connector. This is a multi-mode IBM PC/XT*, PC/AT* and PS/2-compatible bidirectional parallel port. Since the ST16C452 does not supply another parallel port in this design, INTP and INTSEL can be “noconnect.”

The GD75232 driver/receiver from Texas Instruments is used as an interface between the Uand the communication ports. The GD75232 combines three drivers and five receivers in a schip, which decreases the device count and reduces the board space required. One GD7523supports one communication port, which makes the design modular.

Clamped diodes are added for port protection. This is an optional item but it ensures that excvoltage does not cause damage to the GD75232.

3.5 Application Flash

The Intel 28F320S5 flash device from the Word-Wide FlashFile™ memory family operates w5 V on both VCC and VPP.

The BYTE# pin allows either x8 or x16 read/program to the 28F320S5 flash device. When loBYTE# selects 8-bit mode, and address A0 selects between the low byte and the high byte. high, BYTE# enables 16-bit operation, address A1 becomes the lowest order address, and aA0 is not used (don’t care).

The 28F320S5 also incorporates a dual chip-enable function with two input pins, CE0# and CThese pins have exactly the same function as the regular chip enable pin, CE#. Both CE0# aCE1# must be active low to enable the device. If either signal becomes inactive, the chip is disabled. Device selection occurs with the falling edge of CE0# or CE1#. The first rising edgCE0# of CE1# disables the device. For minimum chip designs, CE1# may be tied to ground system logic may use CE0# as the chip enable input.

Memory holes must be used to address the flash. It can either be at 512 Kbyte – 640 Kbyte (080000H-0A0000H) or between 15 Mbyte and 16 Mbyte (F00000H-FFFFFFH). In this desig512-Kbyte window below 16 Mbyte (F80000H-FFFFFFH) is used. General purpose I/O fromNational Semiconductor 87307 Super I/O are used to select one of eight pages in the 28F32memory device.

If the application flash is required to act as a disk, suitable drivers should be used.

3.6 Video Controller

The CL-GD7555 Video and Graphics Controller can control a CRT, TFT, DSTN, or TV displaThe controller supports mixed voltage operation. Active power management provides power-control of selected unused internal functional blocks during display. The CL-GD7555 also connects directly to the 32-bit PCI (v2.1) host bus with a 33 MHz clock rate.

The CL-GD7555’s V-port allows cost-effective implementation of many multimedia features sas MPEG video playback, TV tuning, video capture and teleconferencing. The chip also supTFT flat panel displays (up to 1024 x 768 resolution) and color dual-scan STN flat panel disp(up to 800 x 600 resolution).

In this design, the CL-GD7555 is implemented with a 2-Mbyte frame buffer using four 256K xDRAMs. The TFT/DSTN display is not implemented in this design. The CRT controller generhorizontal and vertical signals (HSYNC and VSYNC) for a CRT monitor. It supports up to 1281024 resolution with 256 colors.

The IDSEL signal is routed to AD13. The INTR signal is connected to PIRQ1.

3.7 Power

Power is supplied to the board through an ATX power connector. ATX power supplies provid5 V, 3.3 V, +12 V, -5 V and -12 V outputs. All these values are used in the design. When usingpower supply there is no need for additional voltage regulators.

12 Application Note


4.0 Design Considerations

There should be decoupling capacitors for every schematic page and one bulk capacitor for the entire design. This provides a short between power and ground for high frequency signals and to reduce inductance.

If a part is to be removed from the design, the outputs can be left unconnected but the inputs should be pulled either high or low. Since the TFT/DSTN display is not implemented for this design, connect the video controller power pins to VCC.

5.0 Summary

This design was created to shorten the development cycle for POS terminal designs. It is intended to be implemented on a single board for reduced cost. Peripherals are designed in a modular fashion and can be easily removed for specific applications.

Caution: The design has not been implemented in hardware. This document is for reference only. Customers are responsible for validating designs created using the information included in this document.
