I would buy my own AT90S and try to debug this with you, but it seems like it is pretty hard to buy datashete AT90S online, and according to Atmel, that chip is a mature product and not recommended for new designs. I have checked the voltage settings, and tried many combinations.


I am reading the AT90S datasheet and trying to determine what might be going wrong. 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!

Faithfully describe 24 hours delivery 7 days Changing or Refunding.

Unfortunately, I do not know what might be going wrong. Freight and Payment Recommended logistics Recommended bank. The resulting architecture is more code at990s8535 while achieving throughputs up to ten times faster than conventional CISC microcontrollers.


I tested a board I found with an megaL, and it worked datasheer. Thank you for your fast reply! 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? The frequency matters too, so what frequency is the clock or crystal?

I have not tested any other controllers, as I have a stock of about s. SeekIC only pays the seller after confirming you have received your order. In that section, it says:.

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. Recent History What is this? The complete avrdude command is: 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.

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.


What kind of clock or at90ss8535 is the AT90S connected to? I have also tried with avrdude, it gives me: Margin,quality,low-cost products with low minimum orders.

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. Month Sales Transactions.

The Power Down mode saves the register contents but freezes the oscillator, disabling all other chip functions until the next interrupt datasehet hardware reset. Please create an account or Sign in.
