hello all, I m using AT89c51 controller.my application icludes reading & writting a 16 bit data into 93c46 eeprom memory using this controller. i've written the code in C. but i m unable to write the data into memory. I've tried all the options but still it is not working Are there any hardware modifications i've to do? Plz reply,thanx
Are there any hardware modifications i've to do? Plz reply,thanx I appreciate the offer to pay in Polish Zloty (PLZ), but I'll answer for free. No, no hardware modifications are required. My guess is that you are trying to write more than 8 bits to the eeprom, no can do, you must split the data. Erik
thanx for the reply. i am using 93c46 serial eeprom.In this memory we can write both 8 bit as well as 16 bit data seperately. i've tried both of them but still it is not working
"we can write both 8 bit as well as 16 bit data seperately. i've tried both of them but still it is not working" Eh??? SO what exactly is your problem? What precisely do you mean by "not working?"
ouchen hatem 46,rue bernaoui saad cite yahyaoui setif algerie. sir , i would you to send me documentation for detecting the code of 87c51 when the bits of securite is activing. best regards
The whole point of setting the security bits is to prevent reading the code! Why do you want to do such a thing?
