ATTINY1614-SSN

Microchip Tech · Microcontroller Units (MCUs/MPUs/SOCs) · SOIC-14

ATTINY1614-SSN from Microchip Tech, 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 Supply pin for the device; the operating supply voltage range is 1.8V to 5.5V.
2 PA4 bidirectional General-purpose I/O pin PA4 on the VDD power domain, multiplexed with ADC0 AIN4, AC0 AIN0, SPI0 SS and TCA0 WO4 functions.
3 PA5 bidirectional General-purpose I/O pin PA5 on the VDD power domain, multiplexed with ADC0 AIN5, VREFA, TCA0 WO5 and CCL OUT functions.
4 PA6 bidirectional General-purpose I/O pin PA6 on the VDD power domain, multiplexed with ADC0 AIN6, the DAC0 analog output and AC0 functions.
5 PA7 bidirectional General-purpose I/O pin PA7 on the VDD power domain, multiplexed with ADC0 AIN7, AC0 AINP0 and CCL LUT1-OUT functions.
6 PB3 passive Pin PB3 doubles as the TOSC1 connection for the 32.768 kHz external crystal oscillator, multiplexed with AC0 OUT and USART0 RxD.
7 PB2/TOSC2 passive Pin PB2 doubles as the TOSC2 connection for the 32.768 kHz external crystal oscillator, multiplexed with EVOUT1, AC0 OUT and USART0 TxD.
8 PB1 bidirectional Digital I/O pin PB1 with ADC0 AIN10 and PTC X4/Y4 functions, also multiplexed to TWI0 SDA and TCA0 WO1.
9 PB0 bidirectional Digital I/O pin PB0 with ADC0 AIN11 and PTC X5/Y5 functions, also multiplexed to TWI0 SCL and TCA0 WO0.
10 PA0/RESET/UPDI bidirectional Pin PA0 is configured through RSTPINCFG as GPIO, RESET or UPDI, and as GPIO its output driver is disabled for 768 OSC32K cycles after a System Reset.
11 PA1 bidirectional General-purpose I/O pin PA1 with ADC0 AIN1 input, multiplexed to USART0 TxD, SPI0 MOSI, TWI0 SDA and CCL LUT0-IN1.
12 PA2 bidirectional General-purpose I/O pin PA2 with ADC0 AIN2 input, multiplexed to EVSYS EVOUT0, USART0 RxD, SPI0 MISO, TWI0 SCL and CCL LUT0-IN2.
13 PA3/EXTCLK bidirectional Pin PA3 can be used as the external clock input EXTCLK, and is also multiplexed with ADC0 AIN3, SPI0 SCK and TCA0 WO3.
14 GND power_in Ground reference for the device supply.

Electrical characteristics

Limits as printed in the datasheet (page.json metadata.characteristics carries them as data).

Parameter Symbol Min Typ Max Unit Conditions Page
Supply voltage 1.8 5.5 V Ordering table, ATtiny1614-SSN: 20 MHz max CPU speed, SOIC, -40°C to +105°C 566
Operating temperature range -40 105 °C Ordering table, ATtiny1614-SSN: 20 MHz max CPU speed, 1.8V to 5.5V 566

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
contacts tin including indium tin oxide (ITO) sensor grids. The PTC requires one pin per X-line and one pin per Y-line. In the Self Capacitance mode, the PTC requires only one pin (Y-line) for each touch sensor. 461

CAD (KiCad official)

  • Symbol: ATTINY1614-SSN
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: attiny1614-ssn-etched.step / attiny1614-ssn-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); attiny1614-ssn.step / attiny1614-ssn.glb are the bare package body.
