Most USART peripherals support a minimum choice between UART or SPI, where as some might support additional choices, such as LIN, IrDA, RS-485. UART/I☬/SPI columns - green cell means a dedicated peripheral, yellow cell means a multi-feature peripheral that is chosen by setting configuration bits.Package column - the number after the dash is the number of pins in the package, DIP means P DIP (Plastic DIP) package with 0.3-inch row-to-row, SOwww means SOIC package with a case width of 'www' in thousandth of an inch, some packages may be known by alternate names.The 4th pin would be the inverse of OC1B on the 3rd pin. ^ 4 pins are usable, but only 3 unique generators can be attached.^ ADC only on ATtiny5/10, and channels are 8 bits instead of 10.This table is not meant to be an unabridged feature list.ĭIP-8N, SO150-8, SO209-8, VQFN-10, WQFN-20 The following table summarizes common features of the ATtiny microcontrollers, for easy comparison.
The entire ATtiny microcontroller family doesn't have any of the following features: USB peripheral, DMA controller, Crypto engine, or external memory bus.
