topic AP16 burn problem in 8-bit Microcontrollers https://community.nxp.com/t5/8-bit-Microcontrollers/AP16-burn-problem/m-p/147784#M7520 <HTML><HEAD></HEAD><BODY><SPAN>Hello, I have 2/10 AP16CFBE pieces masked OM25D that seems to have a flash problem. I charged my firmware trough MON08 / P&amp;E PROG08 software. It didn´t work so I check the flash. I has 0x00 in one row(or column) all along the entire memory, including vectors. I´ve never had that problem. I´m unable to blank the memory. Any comments?</SPAN></BODY></HTML> Wed, 16 Apr 2008 23:21:15 GMT dongustavo 2008-04-16T23:21:15Z AP16 burn problem https://community.nxp.com/t5/8-bit-Microcontrollers/AP16-burn-problem/m-p/147784#M7520 <HTML><HEAD></HEAD><BODY><SPAN>Hello, I have 2/10 AP16CFBE pieces masked OM25D that seems to have a flash problem.
