at89C4051

Hello, This at89C4051 chip is before my time (in my AVR lifespan ;) )

And I was wondering how you program it.. since it doesn't have jtag..

Here is the spec sheet:

So on the older chips, you have to have a programming board like the stk500?

No simple/single cable programming?

thanks

Hello,

The AT89 series is actually an MCS51 family (8051) core not an AVR core. This chip is NOT in circuit programmable and must be programmed using a parallel programmer such as this: www.needhams.com. It is a great chip that I still use today in a few projects.

Thanks,

Dave Miller

Oh :/

So in the last couple of years AVR has moved from using other people's cores (and adding some features) to now AVR developing their own core + peripherals?

thanks-Lee

That is an MCS-51 family chip.  You'd need a programmer to program it.

I think my Needhams EMP-30 will do it.  But there are many programmers 
on the market.  You might find one cheap on eBay.
