if you dont have many ICs of 16c54 it is better to shift to newer vesrsions. if only c54 is preferred, then cosider 16F54 which is flash and ICSP programmable. In fact it is better to consider very new versions than spend money for programmer. you may take help of any friends who can do few chips abd done with it.

Thanks for the info bro. I'm a newbie for programming. But i make some ccts using 16F84A, 16F628A and 12C508. But in this case i wanna try this 4 Digit Digital Clock . So can some one help me to programm this PIC.
As suggested, why not use the 16F54, it's easily programmed replacement?. Without checking on MicroChip I can't be sure, but some of the ancient OTP devices required a parallel programing rather than the newer serial system.
did you see the AN615
operates from 2 cells-- i have modded it to work with 16F84a and with continous display. this works well the 1.8 to 3V max ie., two celss either chargeable or dry cells.

Can I use PIC16F84A for this cct. And what is the meaning " continous display ". Does it mean no fickering rate or very low flickering rate? Is it a 24hour clock?
Thanks ton my friend. I'm going to make it Tomorrow.
original design is also low flicker- but after 8 sec the display will be off. that timing i removed it .
little flickering is due to low spped of refreshing.
you may read the article and only if you like you make-- other wise you can modify the 590 software to suite 16F84A-4

if you try (as some one said, whenthere is a will there is a way) , you will get it , as Nigel rightly said, from old and condemned casio digital watches. and few other sources of scrap.
also you can't just say that thereare no watch repairers and electronic repairers-- components are generally available-- only you have to trace for them . please don't start with negative--
