Different but the same to the attint4808?

Using Arduino Microcontrollers
1

Hello, I was wondering What other processors thatArduino offical oe unoffical support that is close to the atmega4808? Thhe 4808 is close to a 328p processor and I'm looking for one close to it.

Arduino Nano Every uses a 4809.

In what way?

Hello markd833, I will look at that one.

Due to the shortage trying to find a processor that is close to the atmega328p or the atmega4808.

In what way?

Price, pin count, pin out, Flash, RAM, EEPROM, shape, colour, etc

I'm sorry let me rephrase that. I'm trying to find a processor that is close to it in programming space, that has SPI,i2c,Serial communcation, and pin count. It doesn't have to be the same it can be less pincount. But that I need is same programming space with spi, i2c and serial.

Somewhat overkill. But in stock.

I don't know if I agree with that statement, but when using a hardware abstraction layer like Arduino I suppose it might seem so.

Edit: How many do you need? There's a bit of stock of the ATmega4808 and its siblings here and there.

What I meant was I'm trying to find a processor as close to a Atmega328p as possible and the one I found before is a Atmega4808. I'm looking at the AVR128DA32T-E Thank you.

Close is a rather vague term, the atmega4808 is quite different if you use any direct port or register access, and is not fully compatible with a lot of libraries.

So far Every library I ran for oled screens or sensors That I have been running works on the 4808 with no problem yet. Other then running it as a UPDI when programming it is not bad.

Here's a link to all the AVR chips "in stock" at digikey with at least 24 pins, 32k program space, UART, SPI, and I2C: https://www.digikey.com/short/24wzb4zp
Note that some of the chips have less total IO available once you account for "dedicated" functions, and "many" do not have high speed crystal support.

The AVR128DBxxx chips are looking pretty attractive. Your guess is as good as mine as to how long they will stay "in stock."

Hey westfw Thank you very much. I'm working on a project But Paying 4 times a cost for processor is nuts. Even if I can get anything if possible.
