89c51 using rfid

[sameertorvi]

hi guyz, i m working on my third year project based on rfid and referring the circuit, code and components from engineer's garage 

http://www.engineersgarage.com/microcontroller/8051projects/interface-rfid-AT89C51-circuit

  I  have the following querries

1. apart from the 'components' given in the list, i find another 8 pin ic connected to the circuit seen at thr right side of 89c51 given in the picture/video. Does anyone have any idea regarding what that ic is and what is it used for????

2. Can i use 89s52 in place of 89c51 ????since the burner in my college does not support '89c51'.                  

 

thnx……..

hello sameertorvi,

i looked at he link you given above… that 8pin IC is not connected with the ckt… it might be that they have done some mistake… they havn’t removed it before the tkae this video.. any ways nice observation… 

any yes you can you s52/s51 instead of c51 in that ckt…
