I tested a board I found with an megaL, and it worked perfectly. SeekIC only pays the seller after confirming you have received dztasheet order.
Month Sales Transactions. In that section, it says: I am reading the AT90S datasheet and trying to determine what might be going wrong. Margin,quality,low-cost products with low minimum orders.
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 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 Atmel, that chip is a mature product and not recommended for new designs. In that at90s853, it says:. Please create an account or Sign in.

I have not tested any other controllers, as I have a stock of about s. When you place an order, your payment is made to SeekIC and not to datasheey seller. Unfortunately, I do not know what might be going wrong. Thank you for your fast reply! Recent History What is this?
The complete avrdude command is: You may also be interested in: Freight and Payment Recommended logistics Recommended bank. 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. STK never failes at all.
Datashewt Power Down mode saves the register contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset.

We will also never share your payment details with your seller. The frequency matters too, so what frequency is the clock or crystal?
I have also tried with avrdude, it gives me: 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! The resulting architecture is more code efficient while achieving throughputs up to ten times faster than conventional CISC microcontrollers.

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 wt90s8535, but you should probably just use the programmer you have that works. 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.
I have checked the voltage settings, and tried many combinations. What kind of clock or crystal is the AT90S connected to? 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?
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.
