Problem with read memory MX30LF4G28AD-TI Reply  

I have a problem reading memory from MACRONIX MX30LF4G28AD-TI chip. Each time there are differences in the read data.

I use the default settings in "Modify Algorithm Parameters". VCC: 3.00V, tPw 200uS, Page: 2160 and Retry: 25.

Enabling the "Slow Program/Read" option does not help.

Windows 11, Wellon VP998, Firmware Ver.10.0, Program Ver.

Any suggestion?

I try to programm a AT93C56A

I used the small ISP adapter supplied with the programmer. I connected each wire to the pins of the eeprom support, following the instructions. (isp drawing)
The programmer writes that writing is ok, but when I try to read. the eeprom to check by opening the buffer, the file is blank.
I tested several new eeproms and always the same observation.

Where is my mistake?

I have tried so many adapters and I have the WL-TSOP48-U001 and this flash chip will not be recognized as it is in the device. Says No Device in socket.

I have placed the pin 1 of the IC where the white dot is and even used a multimeter to make sure pin 1 on the header matches the one in the socket but it never detects the IC. What adapter is made for TSOP32 with width 20mm? This one is not working nor are the generic ones either.

VP-996 Not programming AM29F032 Reply  
I received a batch of 10 AM29F032 Flash ROMs and tested them on my VP-996 OK. HI programmed 5 last week OK. Now, however, today I"ve come to program the the rest of them and they are all failing on the first address! Changed adaptors with no success!

I"ve run the self-test, which passes OK. On checking the test Voltages I get these:
VCC 3V = 3.22 : VPP0 12V = 13.13 : VPP1 12V = 13.17 : VPP0 25V = 27.60 : VPP1 25V = 27.98
