The I/O Controller also provides an interface for all sensor systems, several

visual indicators, and power and control of other systems throughout the

PS288. Sensor conditions are reported back to the Handler Computer

through a series of connections on the rear of the I/O Controller. Connections

supported by the I/O Controller include:

• Air pressure sensors

• Light tower

• Tube vibration assemblies

• Component position optics

• Vacuum and pressure control solenoids and sensors

• Safety shield interlocks

• Tape output control and associated sensors

• Power contactor for the laser marking stage

• Label and laser marking system controls and associated sensors

• Additional connectivity for future options

For a listing of status indicator lights on the I/O Controller, see Appendix A,

“I/O Controller LED Status.”

PS288 Owner’s Manual 4—3

FlashCORE programmers on the PS288 are made up of the following com-

ponents:

CPU - PowerPC Controller Board (RPX-Lite)

The PowerPC Controller Board is based on MCP850 PowerPC CPU and

includes many hardware elements, like 10 Base-t Ethernet port and a

PCMCIA interface.

It has a memory controller that allows the device programming algorithm to

control the bus cycle timing for the memory range used for programming.

The onboard I2C bus is used to address a serial EEPROM on the adapter

board of the programmer to collect statistics on a given socket. The I2C bus

is also used on the RPX Lite Board to address the temperature and thermal

monitor (STTM) and another onboard serial EEPROM used for RPX config-

uration storage.

Waveform Board

The core of the FlashCORE programmer design, the Waveform Board inter-

faces to the PowerPC Controller Board with two programmable logic

devices: a CPLD (non-volatile) and a FPGA (volatile). These two logic

devices make up the basic programmer control circuitry. The CPLD contains

logic to control the communications interfaces as well as the analog controls

of the programmer and configuration of the volatile FPGA. The FPGA is

used to route address, data and control signals from the PowerPC to the

devices in socket, and provide Device Insertion, V

waveform generation,

and Self-test circuit control logic.

Backplane Board

The Backplane Board is a connection scheme to connect the Waveform

Board to the Socket Adapter board. In addition to supplying connections

between the two boards, it also supplies the circuitry for address line buffer-

ing to isolate each device so that a failing part cannot affect non-failing

devices and power and ground switching relays.

Socket Adapter Board

The Socket Adapter Board connects to the Backplane Board to supply the

electrical connections for programming to the individual sockets. It also con-

tains a 10 bit ID bus used to identify the adapter installed. A small EEPROM

exists on this board for maintaining socket cycle counts for this physical

adapter. By putting this EEPROM on the adapter itself, the socket cycle

counts for a specific Socket Adapter Board can be tracked independent of

the FlashCORE programmer it has been installed on.

In each FlashCORE programmer, there is a PCMCIA card that acts as the

local drive for the FlashCORE programmer. There are various sub-directo-

ries and files on this, as shown in Figure 4-2.

Power to FlashCORE programmers is provided by a universal power supply,

which powers two FlashCORE programmers.

4—4 PS288 Owner’s Manual

Each programmer is connected to the 16-port network hub via a UTP cable

with RJ45 connectors at both ends. The network hub is also connected to the

Handler Computer, which communicates to all FlashCORE programmers

during the device programming process and when running diagnostics tests

on a FlashCORE programmer.

Computer

System

The computer system of the PS288 consists of the Handler Computer and

various networking components that allow the Handler Computer to com-

municate with the FlashCORE programmers.

Handler Computer

The Handler Computer operates using the Microsoft

Windows XP operat-

ing system and the client network communications. It hosts TaskLink and

the AH500 operating software, as well as several subsystems within the

machine including:

• Vision system and software

• PNP head motion control system

• Label marking system

• I/O Controller interface

The Handler Computer communicates with the network by a 10BaseT Ether-

net connection, and contains mappings of all the major disk volumes used by

the network. Any data transfer required from a major network volume can be

accomplished on the Handler Computer using Windows

Explorer.

The PS288 user interface (AH500 software) is run from the Handler Com-

puter. It contains all graphic components that the system operator uses dur-

ing normal operation, including option configuration, programmer setup,

and system adjustments.

The vision interface card is installed in the Handler Computer, as well as its

operating software. This system is run in conjunction with the AH500 oper-

ating software to ensure proper alignment of programmable devices before

being placed into the programming sockets.

The motion control system interface allows the AH500 software to commu-

nicate with the PNP head gantry system. Movement commands and posi-

tional feedback are provided to the AH500 software with this system.

The Handler Computer and AH500 software communicate with the label

marking system via serial port on the rear of the Handler Computer. Label

data transfer and labelling system responses are sent to and from the label

marking stage through this connection.

The I/O Controller interface determines the condition of the various sensors

and systems located throughout the PS288 as reported to the I/O Controller.

These conditions are then read by the AH500 software to determine the state

of the machine before issuing system commands. See Appendix A, “I/O

Controller LED Status.”
