Frequently asked questions
How do I program the ATtiny13A?
It is programmed through the ISP interface over SPI, using the MOSI, MISO, SCK and RESET pins. A USBasp programmer or an Arduino board set up as an ISP programmer is commonly used.
Can it run on a 3.3V supply?
Yes, its supply range starts at 1.8V, so both 3.3V and 5V are within specification. The maximum usable clock speed depends on the supply voltage, so check the datasheet for the speed at your voltage.
