  • Unless I'm seeing wrong, you say "AVR 8 Pin 10MHz 2K 4A/D - ATtiny13" and then say it has 1K program space? Eh? And is it 10 or 20MHz max clock?

  • I just created a tutorial for programming these with an arduino (ISP).

  • As of 5-15, these are still ATTiny13, not the newer Tiny13A model.

    • As of April 24th, 2010 Sparkfun is still shipping the older ATTIny13 and not the ATTiny13A.

  • Is this the 13A component or the older 13?

  • check out my tutorial in how to program this microcontroller with avr studio 4 and the avrisp mkii:

  • Does this have the same pinout as the attiny 45?

  • Hi,
    newbie here,
    I want to control 4 RGB LEDs with a small microcontroller. Is it possible to do it with this one? I didn't understand from the description or the datasheet if this micro supports PWM outputs.

    • Hi Dimitris,
      This micro has two PWM outputs by default, and it can drive up to 5 or 6 PWM using software PWM. However, each RGB LED will need 3 channels, bringing your total needed to 12 (4 x 3) outputs.
      You might want to check out an attiny 2113 or atmega 328P (used in the recently updated Arduino Uno). Alternatively, you could get a TLC5940 16-channel LED driver, and interface with that via serial from a small micro like the attiny13 (here) or the attiny85.

  • Digi-Key has the ATtiny13A for $1.72

    Max clock is 20MHz, 1k flash
