89c51 hex file downloading

how to load hex file parallel port

hi..i started new to at89c51 programming and wonder what are the pins for downloading and how the hex file is really getting downloaded apart from the actual hex file we create ! I'll be thanful if any help ..

hex file 89c51 burner

at89c51 requires external burner to load the hex file into the controller
instead you can use at89s51 which is same to c51 except it has ISP facility
so using only 3 pins we can program the hex file

hex file 89c51 burner programmer

To program 89S52 in ISP mode, 4 signals are required apart from Vcc and GND

MOSI
MISO
SCK
RST
Vcc
GND

Good luck

load hex file into 89c51

thank you all..my intent is to clarify on addr/data pins connected with the target 89x51 in parallel port programming mode..also /PROG,RST,/INT0,/INT1,T0,T1 and other control pins for downloading the hex file into target 89x51.so what is the sequence of downloading so that we can write necessary code development for hex file and hw design for schematics.

Your question is a bit confusing. Are you asking the programming sequence about how the micro is programmed in a parellel programmer, or you are asking how wrote a source code?
