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

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
Lee
