Figure 1 shows the circuit diagram of the SPI Flash programmer hardware interface, the power to the interface is provided either by a 9V dc adapter or a 9V battery. The 74HCT367 IC buffer the parallel port signals.
FlashProg is USB base flash memory programmer which is specifically design to read and program 3.3V SPI flash memory devices. Selection of software according to 'Serial eeprom programmer schematic' topic. Find Serial EEPROM Programmer Schematic related suppliers. SST25VF512 Serial Flash Memory SST25VF512 SPI serial flash memory is manufactured with SST's.
It is necessary to use the HCT type IC in order to make sure the programmer should also work with the 3V type parallel port. The 74HCT04 is used to generate the clock signal for the u-controller when programming the device in stand-alone mode. Figure 1: Circuit Diagram of the SPI Flash Programmer.

Place all files in the same folder. The main view of the program is shown in figure 3.
Also make sure do not program the RSTDISBL fuse in the AVR series devices, unless it is necessary otherwise further serial programming is disable, to restore the serial programming a high voltage parallel programmer is required. For the fuses setting consult the datasheet of the respective u-controller.
The first ROM devices had to have information placed in them via some mechanical, photolithographic, or other means (before integrated circuits, it was common to use a grid where diodes could be selectively installed or omitted). The first major improvement was a 'fuse-PROM'--a chip containing a grid of fused diodes, and row-drive transistors that were sufficiently strong that selecting a row and forcing the state of the output one could blow the fuses on any diodes one didn't want. Although such chips were electrically writable, most of the devices in which they would be used did not have the powerful drive circuitry necessary to write to them. Instead, they would be written using a device called a 'programmer', and then installed in the equipment that needed to be able to read them. The next improvement was an implanted-charge memory device, which allowed charges to be electrically implanted but not removed.
