ATTINY1624-SSU
MICROCHIP TECHNOLOGY · Global Sourcing Parts · SOIC-14
ATTINY1624-SSU from MICROCHIP TECHNOLOGY, in a SOIC-14. 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 | VDD | power_in | Power supply pin; supply voltage range is 1.8V-5.5V per the ordering table, with a decoupling capacitor placed close to the pin. |
| 2 | PA4 | bidirectional | PORTA pin 4 general-purpose I/O with ADC0 input AIN4, USART0 XDIR, SPI0 SS, TCA0 WO4 and LUT0-OUT functions. |
| 3 | PA5 | bidirectional | PORTA pin 5 general-purpose I/O with external reference input VREFA, ADC0 input AIN5, AC0 OUT, TCA0 WO5, TCB0 WO and alternate LUT3-OUT functions. |
| 4 | PA6 | bidirectional | PORTA pin 6 general-purpose I/O with ADC0 input AIN6 and AC0 negative input AINN0; has full asynchronous pin-change detection. |
| 5 | PA7 | bidirectional | PORTA pin 7 general-purpose I/O with ADC0 input AIN7, AC0 positive input AINP0, LUT1-OUT and alternate EVOUTA functions. |
| 6 | PB3 | bidirectional | PORTB pin 3 general-purpose I/O that serves as 32 kHz crystal input TOSC1, with USART0 RxD, alternate WO0 and LUT2-OUT functions. |
| 7 | PB2 | bidirectional | PORTB pin 2 general-purpose I/O that serves as crystal pin TOSC2 and EVOUTB, with USART0 TxD, TCA0 WO2 and LUT2-IN2 functions; has full asynchronous pin-change detection. |
