The on-chip ISP Flash allows the program memory to be reprogrammed in-system through an SPI serial interface or by a conventional nonvolatile memory programmer.

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!

STK never failes at all. I would buy my own AT90S and try to debug this with you, but it seems like it is pretty hard to buy the AT90S online, and according to Datasehet, that chip is a mature product and not recommended for new designs. The Power Down mode saves the at90s85355 contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset.


I have not tested any other controllers, as I have a stock of about s. Shop Blog Forum Support.

Month Sales Transactions. The complete avrdude command is: In that section, it says:. You may also be interested in: What kind of clock or crystal is the AT90S connected to?

Freight and Payment Recommended logistics Recommended bank. Margin,quality,low-cost products with low minimum orders. The frequency matters too, so what frequency is the clock or crystal?

When you place an order, your payment is made to SeekIC and not to your seller. The resulting architecture is more code efficient while achieving datasheey up to ten times faster than conventional CISC microcontrollers.

We have not tested the programmer with the AT90S and I do not know of any customers who have done that either, so there might be trouble getting it to work. I have checked the voltage settings, and tried many combinations.

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. SeekIC only pays the seller after confirming you have received your order.


I am reading the AT90S datasheet and trying to determine what might be going wrong. In that section, it says: I tested a board I found with an megaL, and it worked perfectly.

I have also tried with avrdude, it gives me: Thank you for your fast reply! I tried changing the crystal to 8MHz, and it did not help, could it be that the delay satasheet the AVR responds is too short for the old controllers? 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.

We will also never share your payment details with your seller. 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.
