The 4313 has landed

One of our all-time favorite chips is the ATtiny2313.

It’s a little 20-pin AVR microcontroller that we’ve used in dozens of projects, including our high tech holiday decorations, some of our coolest pumpkins, our (digital) Larson Scanner, and some wacky papercraft– to name a few. It’s one of those few chips that we used often enough to justify a custom breakout board.

But… if there’s one thing that the ‘2313 is short on, it’s memory. With 2 kB of flash (program) memory and 128 bytes of RAM, it’s perfect for tiny single-purpose projects. But, it’s oh-so-easy to run up against that memory limit. And, that’s why we were so excited when Atmel began to announce their then-forthcoming ATtiny4313 in late 2009.

Unfortunately, it’s often a long delay between when a chip is announced and when it’s actually available through distribution. Sample quantities have been floating around for half a year or so, but– and finally– a big box showed up in the mail, and so here they are.

  1. Perhaps an odd question…but what’s the pricing? Is it about the same price/unit as ATtiny2313 or much higher?

  2. Good News!
    Now I need to wait until he appears in Russia. %)

  3. Farnell still has 32 in stock, wonder for how long…

  4. Still no A/D 🙁

    But the extra code space and low current sleep mode are very welcome. The tiny461 is a kinda cool substitute, but some times you need an extra two pins and I guess the USART in the tiny2313 is handy.

Sorry, the comment form is closed at this time.
