Ulf, what of these new AVRs? :)

Started by larwe January 10, 2006
The other week I was downloading the ATmega128 datasheet to check
something and I noticed the mega640/1280/1281/2560/2561.

Any idea when these are going to be available? Digi-Key shows the 2560
and 2561 but zero stock; the others don't show up at all.

Are the 128K flash variants going to be cheaper than the ATmega128L?

They are called vapourware. They are available when they are available. Whatever this means. Rene
Hello Rene,

You mean testing market interest without having any product? That would be a recipe to alienate the customer base. With TI's MSP430 at least they usually have samples when they post the specs. Sometimes even before the specs are complete. Regards, Joerg http://www.analogconsultants.com

Pity, because the 256 price is approx. the price of the old mega128L - which makes me hope strongly that the 1280/1281 will be cheaper.

You can both be right :) When they are (eventually) released, you can expect them to be cheaper. Higher code sized AVRs are also under price pressure from the many ARMs. -jg

I may be able to turn the ATmega256/2560s/1281s etc. I have into smoke, but I am not sure I know how to turn them into vapour... The 2561 was the first part to be available and the others are following. It simply takes time from first silicon to full production so Rene is right, they are available (at Digikey) when they are available. Pricing is market driven... -- Best Regards, Ulf Samuelsson ulf@a-t-m-e-l.com This message is intended to be my own personal view and it may or may not be shared by my employer Atmel Nordic AB

I was looking at this very issue the other week for a project that is currently in a mega128 at 8MHz. I need more CPU horsepower, and more RAM would be very helpful; I was going to just zip up to 16MHz but looked around for other options. I'm currently paying this: ATMEGA128-16AI 128K flash/4K RAM/4K EEPROM/48 IO/10ADC/16MHz $15.05 qty 1 $8.75 qty 100 I can buy: AT91SAM7S256-AU-001 256K flash/64K RAM/32 IO/55MHz $12.04 qty 1 $7.28 qty 100 or LPC2129FBD64-S 256K flash/16K RAM/46 IO/10ADC/60MHz $10.68 qty 1 $8.52 qty 100 The cost difference at the qty 100 price is almost all eaten by the need to buy external EEPROM or ADCs, plus the different code density means I don't get 2x advantage out of the 256K flash.

why not the LPC213x? for the specs you gave they're cheaper.... Or the TMS470?

Are you using that much FLASH for data or code? If it's for data (const tables, strings and so on...), maybe you could use something like an LPC2103 + M25P40 or something similar...

It's code. Ideally I'd like 256+K of flash, at least 6 slow A/Ds, 16K of RAM and hardware SPI and I2C (both usable simultaneously, not muxed onto the same pins).
