Hey i was looking for the cheapest uC out there to have fun around with and to put these in various small circuits ..

The lowest i could find was Atmel 80c51 ( 4 kb flash 40 pin ) - Rs 90

Does anyone know of anything cheaper ????

At89C51 costs Rs. 65/- only.

yup PICS start 100/- and up...but these are the 14bit ones...Don't know abt the 12bit ones...their smaller 8 pins and maybe cheaper....

Silll the best bet is atmel 51 .It's around 40 to 50 Bucks in Mumbai :D

hi,
How much does a Chip-Programmer cost??Do we get schematic for a 8051 chip-burner/downloader?

Well u can get a few circuit diagrams of uC programmers on the net. But these circuits does not support a wide range of IC's. Each time you want to try anything new, u get into trouble.

A good programmer may cost you around Rs 4000, and that will support a wide range of uC's.

I feel the best uC to start with is AT89C2051, it's cheap, easy to program yet has a lot of features...as well as compatible with it's higher family members such as AT89C51, AT89C52, AT89C55 etc... You may also try the Atmel S series AT89S52 etc.. these can be directly programmed by the PC parallel port. Tell me if u need more help in this matter.

2051 ishighly recommended ... you can move to higher end versions once u get a hang of the 51 arch .

Hi!
Affording programmer of Rs. 4000/- for beginner is a problem. Can you please suggest some silmple circuit as avialable for PIC?

Almost all ATMEL 8051 family processors have their S (In Circuit Programmable) version available. With some knowledge of computers they can be programmed by the serial / parallel port of the comp. For details may refer to AT89S52.pdf (search on google)...Programming these needs hardly any investment !!! I have done it and is a wonderful feature of the uC's.
