I tested a board I found with an megaL, and it worked perfectly.

I am reading the AT90S datasheet and trying to determine what might be going wrong. The frequency matters too, so what frequency is the clock or crystal?

In that section, it says: 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.

Margin,quality,low-cost products with low minimum orders.

What kind of clock or crystal is the AT90S connected to? We will also never share your payment details with your seller.

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. Freight and Payment Recommended logistics Recommended bank. Thank you for your fast reply! I would buy my own AT90S and try to debug this datqsheet 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.

The Power Down mode saves the register contents but freezes the oscillator, disabling all other chip functions until the next interrupt or hardware reset.

I have also tried with avrdude, it gives me: I tried changing the crystal to 8MHz, and it dataaheet not help, could it be that the delay before the AVR responds is too short for the old controllers? SeekIC only pays the daasheet after confirming you have received your order. 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.

We have not tested the programmer with the AT90S datashdet I do not know of any customers who have done that either, so there might be trouble getting it to work.

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! 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 throughputs up to ten times faster than conventional CISC microcontrollers. Shop Blog Forum Support. The complete avrdude command is:
