Margin,quality,low-cost datasjeet with low minimum orders. The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

The Power Down mode saves the register contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset. If you want to look at the programming lines on an oscilloscope and diagnose the problem, that might allow me to make a firmware update that fixes the problem, but you should probably just use the programmer you have that works.

We will also never share your payment details with your seller. The frequency matters too, so what frequency is the clock or crystal? Unfortunately, I do not know ddatasheet might be going wrong. STK never failes at all. Thank you for your fast reply!

Month Sales Transactions. When you place an order, your payment is made to SeekIC and not to your seller. Freight and Payment Recommended logistics Recommended bank.

I have also tried with avrdude, it gives me: Please create an account or Sign in. I would buy my own AT90S and try to debug this with you, but it seems like it at90w8535 pretty hard to buy the AT90S online, and according to Atmel, that chip is a mature product and not recommended for new designs.

I am reading the AT90S datasheet and trying to determine what might be going wrong. What kind of clock or crystal is the AT90S connected to?

The on-chip ISP Flash allows the program memory to be reprogrammed in-system through an SPI serial interface or by a conventional nonvolatile at90s5835 programmer. SeekIC only pays the seller after confirming you have received your order. In Power Save mode, the timer oscillator continues to run, allowing the user to maintain a timer base while the rest of the device is sleeping.

Recent History What is this? All the 32 registers are directly connected to the Arithmetic Logic Unit ALUallowing two independent registers to be accessed in one single instruction executed in one clock cycle. In that section, it says:. Shop Blog Forum Support. I tried changing the crystal to 8MHz, and it did not help, could it be that the delay before the AVR responds is too short for the old controllers?


I have checked the voltage settings, and tried many combinations. I tested a board I found with an megaL, and it worked perfectly. We have not tested the programmer with the AT90S and I do dataaheet know of any customers who have done that either, so there might be trouble getting it to work. You may also be interested in: In that section, it says: The complete avrdude command is: Faithfully describe 24 hours delivery 7 days Changing or Refunding.

I have not tested any other controllers, as I have a stock of about s.

I looked at the two datasheets wide by side and the only difference I can see in the text and the drawing is that on the the RESET pin is shown to be connected to GND!
