ATTINY461A-PU
Microchip Tech · Pre-ordered MCUs · PDIP-20
ATTINY461A-PU from Microchip Tech, in a PDIP-20. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | PB0 | bidirectional | Port B bit 0 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are MOSI/DI/SDA/OC1A/PCINT8. |
| 2 | PB1 | bidirectional | Port B bit 1 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are MISO/DO/OC1A/PCINT9. |
| 3 | PB2 | bidirectional | Port B bit 2 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are SCK/USCK/SCL/OC1B/PCINT10. |
| 4 | PB3 | bidirectional | Port B bit 3 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are OC1B/PCINT11. |
| 5 | VCC | power_in | Supply voltage pin, operating range 1.8 to 5.5 V per the operating voltage specification. |
| 6 | GND | power_in | Ground reference pin for the device. |
| 7 | PB4 | bidirectional | Port B bit 4 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are ADC7/OC1D/CLKI/XTAL1/PCINT12. |
| 8 | PB5 | bidirectional | Port B bit 5 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are ADC8/OC1D/CLKO/XTAL2/PCINT13. |
| 9 | PB6 | bidirectional | Port B bit 6 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are ADC9/INT0/T0/PCINT14. |
| 10 | PB7 | bidirectional | Port B bit 7 is a bi-directional I/O pin; it doubles as the RESET input, where a low level longer than the minimum pulse length generates a reset, and can otherwise be used as a weak I/O pin. |
| 11 | PA7 | bidirectional | Port A bit 7 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are ADC6/AIN1/PCINT7. |
| 12 | PA6 | bidirectional | Port A bit 6 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are ADC5/AIN0/PCINT6. |
| 13 | PA5 | bidirectional | Port A bit 5 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are ADC4/AIN2/PCINT5. |
| 14 | PA4 | bidirectional | Port A bit 4 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are ADC3/ICP0/PCINT4. |
| 15 | AVCC | power_in | Analog supply voltage for the ADC, analog comparator, BOD, internal reference and Port A; it should be externally connected to VCC, through a low-pass filter if the ADC is used. |
| 16 | AGND | power_in | Analog ground pin. |
| 17 | PA3 | bidirectional | Port A bit 3 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are AREF/PCINT3. |
| 18 | PA2 | bidirectional | Port A bit 2 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are ADC2/INT1/USCK/SCL/PCINT2. |
| 19 | PA1 | bidirectional | Port A bit 1 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are ADC1/DO/PCINT1. |
| 20 | PA0 | bidirectional | Port A bit 0 is a bi-directional I/O pin with an internal pull-up that can be enabled individually; alternate functions are ADC0/DI/SDA/PCINT0. |
