Then apply a voltage(hi or lo) on that pin. This way is 100% guaranteed working.ДЇor the RESET signal on Microprocessor, most likely you need read the Microprocessor datasheet and find the RST pin on the Microprocessor. The simplest way to read/write the chip is to remove the chip from the PCB and put it on the programmer. Sorry for the newbie questions but I'm quickly getting out of my depth here! So, could the Willem Eeprom programmer be modified to achieve either (or both) these solutions? Is the voltage to Vcc adjustable - would a simple resistor in-line with the chip Vcc leg work? I don't know what voltage would be needed but I guess I could experiment. Or I have to connect a MCU Reset Line (RST) (presuambly to the microcontroller chip not the eeprom?) somehow:ДЄs you can see both these options are $$$ and a therefore a no-go (I might as well pay for a new airbag unit). I have to supply the eeprom with a low voltage to avoid interference from other parts or the microcontroller: I came across two possible problems/solutions: It seems that in-circuit programming (or is that ISP?) of 93c46 eeproms is not so simple as I had hoped. Following your suggestion I googles around a bit. But this does not mean it 100% works in your case. There are many user reported they successuly in circuit programmed EERPOM by Willem programmer.

It is designed for mother board BIOS in-circuit-programming. However, this adapter is not designed for 93CXXX EEPROM. You may need a in-circuit-programming driver. The signal may distorted when it reach the chip from the programmer. So, this is why some programming do not work.ДЄlso, the wires you connect the programmer to chip may not meet the signal requirement. The programmer only provide guaranteed power for a single chip. It is pretty much depending on the EEPROM circuit.

The in-circuit-programming are not guaranteed since the programmer is not designed for programming that way. I want to know if the Dual Power Willem Universal EPROM Programmer advertised on MCUMall would work better?ДЄll those programmers are designed for programming EEPROM in ZIF socket. So I have come to the assumption that the eeprom programmer does not work or is not suitable. What is going on? I'm obviously getting something because if I disconnect a pin I get nothing. If I read 4 or 5 times in quick succession then I get all 'FF'. Sometimes the display shows a few values, then if I read again I get a few more. Now when I try to read the chip I get spurious readings. It is supplied with the Ponyprog software.ДЄnyway, I have connected the 93Cxx ZIF socket connections via wires and sub-miniature probe clips to the legs of the chip. I believe it to be a Microwire compatible eeprom so I purchases a simple eeprom programmer on eBay from this place: I have been trying to read (first!) and write an ST eeprom with the following no.s written on it: In-circuit eeprom programming of 93C46CB3 SEP-EE35 (cable with SOP-8 test clip.MCUmall EPROM BIOS Chip Burner Forum - In-circuit eeprom programming of 93C46CB3

Supported devices: you can read and program more than 2000 devices in autodetect.

Incircuit eeprom programmer software#

Software Update: Internet automatic updates. SOIC8 SOP8 Clip DIP8 for in-circuit programming For EEPROM 93CXX/25CXX/24CXX on ZIP USB Programmer TL866 EZP2010 RT809H CH341A straight clip.

Connecting cable: each cable is dedicated to specific device' categories (for instance with cable 93 you can read all kind of SOP8 93xx both 8 and 16 bits data).

Editor: you can use and connect the majority of the editors on the market (for instance 010 Editor) with the EECLIP software.

Autodetect: the software automatically recognizes the connected device.

EECLIP can work both on 3V and 5V devices. It can also supply up to 300mA power to the connected (target) device.

Power supply: no external power supply needed.

Designed to be easy to use: read or write a device in just 2 clicks.

There is a connection wire, with the related Test Clip, for every Eeproms' class.
