Hello, here's a site where you have everything it takes to read and write to the microprocessor MB90F546GS

http://isp-mb9x.sourceforge.net/

Here is a diagram of the connector for connection to the microphone interface card:

this will do the MB90F546GS in circuit part number if link is corrupt is

My interface doesn't have connector, is it possible to reflash it anyway

or the pbc is incompatible?

thanks

Hi

You can solder a connector on the slot or weld son directly on the site for the flash of micro MB90F546GS!

A doubt

its necessary to remove the winbond eeprom for programming or can be done in circuit?

thanks

Some do, for my part I always flash my SPI (winbond or SPANSION) with a SOIC clip is I never had any problems ...

I already tried with a clip but no success, pins 7 and 8 are connected together.

It's normal....
On pcb pin 7 (/hold) and pin 8(VCC) are connected together but for programming SPI flash with clip and universal programmer no soucy ....

What kind of cable rs232 should be used to program?
A nullmodem (crossed) or direct?
