This programmer is designed for programming memory chips with parallel interface and microcontrollers. It connects to the LPT port of a computer and is controlled by the "Willem" programmer software (v0.97ja). Actually, the programmer is a revised version of Willem.

All control signals are routed out to a 40-pin IDE connector, which is used to be found on the computer motherboards, and also to a 32-pin ZIF-socket. Some signals can be cut off from the socket by DIP-switches J1, J2, J3 and jumper JP4, thus achieving compatibility of the programmer with chips in various packages (see schematic).

Supply and programming voltages are set by DIP-switches SA1 and SA2, respectively.

Vdd SA1
1 2 3 4
3,3 ON ON ON ON
4,0 OFF ON ON ON
5,0 OFF OFF ON ON
5,8 OFF OFF OFF ON
6,2 OFF OFF OFF OFF

Vpp SA2
1 2 3 4 5 6 7
12,0 ON ON ON ON ON ON ON
12,8 OFF ON ON ON ON ON ON
12,9 OFF OFF ON ON ON ON ON
14,0 OFF OFF OFF ON ON ON ON
15,0 OFF OFF OFF OFF ON ON ON
21,0 OFF OFF OFF OFF OFF ON ON
21,5 OFF OFF OFF OFF OFF OFF ON
25,8 OFF OFF OFF OFF OFF OFF OFF

Even more voltages can be generated by using different switch combinations.

Jumper JP3 allows one to disconnect the programming voltages from the Vpp line, if needed, and the DIP-switch SA3 is used to set various voltages on that line.
Jumper JP2 is intended to lower the supply voltage on 0.7V by maintaining regular logic levels on the signal lines.
When the programmer is used in the read mode, jumper JP1 along with transistor VT1 is used for short cutting resistors R18 and R19 to ground, which reduces the Vdd voltage.
More details on this can be found on the "EzoFlash+" programmer site and forum.

The printed circuit board is designed for caseless version of the programmer, and is intended for mounting on a rigid flat plate (4mm plywood in the author’s version).
CAUTION! If you are not going to put the programmer into some sort of protective enclosure, then special attention should be payed to the electrical safety requirements for the power supply assembly, in order to eliminate a possibility of an accidental touch to the high-voltage lines.

Assembly and voltage adjustment:

  1. Solder all wire jumpers.
  2. Solder all resistors (excluding the voltage setting ones: R8, R11, R15, R18, R19 and R9, R13, R16, R21, R26, R29, R34, R35). Also solder all Zener diodes.
  3. Solder all capacitors (excluding electrolytic ones), the power switch, the rectifying diode bridge, and all other diodes.
  4. Solder all transistors, voltage regulators, jumpers, and DIP-switches.
  5. Solder the LPT connector X1, the adapter connector X2, and the ZIF-socket. This way it would be more convenient to measure the generated voltages, but slightly less convenient to solder and adjust the voltage setting resistors, so this step can be moved after step 7.
  6. Connect an external 30V power supply, preferably with an overcurrent protection, in place of the secondary winding of the power transformer (XT1 and XT2).
  7. Turn on the power supply (set the protection current limit at 100mA), and by using the DIP-switches and adjusting the voltage setting resistors set up the required voltages according to the table. The voltages can be measured on the ZIF-socket, or on X2 pins.
  8. Solder all logic chips.
  9. Solder the electrolytic capacitors.
  10. Clean the board.
  11. Repeated the voltage control.
  12. Solder the power transformer, fuse, and power cord.
  13. Make the final board clean-up.
  14. Control the voltages again.
  15. Connect the programmer to a computer and check the test signals.

Recently an interesting chip M5M23C100 from Mitsubishi came across.
It is a 1MB masked ROM but squeezed into a 28-pin package.
Here is a bit modified version of the programmer.

Intended for programming chips in PLCC-32 packages and DIP-versions in 32-pin packages.
Note that the circuit board has a small inter-conductor space, and the socket was soldered with a hot-air gun by using a solder paste.
