INTRODUCTION TO THE CHIPMASTER 2000
     
  • OVERVIEW 

    • The Chipmaster 6000 is a universal device programmer which works through your PC's parallel port.
    It features a 48-pin universal pin driver and an expandable TTL pin driver. An on-board processor and FPGA let it handle today's (and tomorrow's) complicated DIP-type silicon PLD's, microprocessors and high density memory chips without adapters. We designed the Chipmaster 6000 for both laboratory and mass-production applications. It supports over 1200 different devices, including PAL, GAL, CPAL, EPLD, PEEL, MAX, MACH, PLSI, microprocessors, EPROM, series EPROM, PROM, and Flash memory. Optional ROM emulator modules support devices up to 16-bits. 
  • FEATURES

    • Socket and Pin Driver 
    48-pin DIP/ZIF socket for 8- to 48-pin 300 / 600 mil devices
    Four DACs for V CC , V PPI , V PP2 and V PP3 with 8 bit resolution.
    Software controllable rise time and current protection.
    TTL driver supports pull-up/pull-down or tri-state control (software selected) on all 48 pins. 
  • DEVICE SUPPORT

Here you'll learn how to:

  • Prepare an EEPROM for programming
  • Link the ChipMaster to a variety of popular EEPROMs
  • Read the contents of an EEPROM
  • Program an EEPROM
  • Verify your program
Let's get started...		  
When you start the ChipMaster 6000, you are presented with the following screen. Basically, it confirms that the ChipMaster has been found on the printer port and is ready for action.

As a demonstration of the general features of the ChipMaster, the following steps will show how to program an EEPROM.

.

STEP 1: Setup
 
 

Insert an EEPROM into the ChipMaster's ZIF (zero insertion force) socket. When the ZIP's lever is in the up position, it is ready to accept a chip. Secure the chip by returning the lever to the down position.

This demonstration will use the SGS-Thompson M27C64A, which is a 8Kx8 CMOS EPROM 200nS.

Pull down the Device menu and choose Auto Select EPROM Alt+A.

or press 

The pop-up box presents two options: choose the first (M27C64A).

.

STEP 2: Verify

To be assured that the EEPROM is blank, preform the following steps:

1. Pull down the Device menu and choose Read Alt+R. 

or press 

(The green "Busy" light on the ChipMaster will flash, indicating a read operation.)

2. Then pull down the Device menu and choose Edit Alt+E.

or press 

.

STEP 3: View Memory Contents

Voila, you're looking at the EEPROM's contents!

Every location contains "FF" which is the hexadecimal representation of the binary string "1111 1111". This indicates that the EEPROM is empty, and ready to program. If the contents weren't all "FF's" the software would not allow us to program (overwrite) the device. We would have to erase the EEPROM by exposing it to ultraviolet light before moving ahead.

.

STEP 4: Change Memory

To change memory contents, simply cursor to the memory location, and type in a new value. Memory locations 0000000 to 000000F have been loaded with the hexadecimal values 01 to 10, while locations 0000020 to 000002F contain the hexadecimal values for the ASCII characters spelling my and my partner's first names. Note how the Text box to the right of the memory dump displays the ASCII representation of memory.

This new assignment of memory will now be programmed into the EEPROM. And once this data is programmed, it will remain for several years until the EEPROM is again erased.

Click the  button to close the pop-up window.

.

STEP 5: Program

Once again, pull down the Device menu and this time choose Program/Auto Alt+P.

or press 

(The green "Busy" light on the ChipMaster will flash, indicating a program operation.)

 

.

STEP 6: Confirm

Repeat STEP 3 to confirm that you have successfully programmed the device.

This screen indeed confirms that the desired locations have been changed. Had this program not been trivial, the EEPROM might contain a computer's BIOS program, or the code for Space Invaders.

Hopefully, this demonstration shows how easy it is to program an EEPROM. Programming is easy -- deciding what to program is the hard part!
