# ATSAMD10C14A-SSNT

**Microchip Tech** · Pre-ordered MCUs · SOIC-14

ATSAMD10C14A-SSNT 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 | PA05 | bidirectional | General-purpose I/O on VDD supply with EXTINT[5], ADC AIN[3], AC AIN[1], PTC Y[3], SERCOM0 PAD[3]/PAD[1] and TC1/WO[1] or TCC0/WO[1] muxed functions. |
| 2 | PA08 | bidirectional | General-purpose I/O with EXTINT[6], SERCOM1 PAD[2], TCC0/WO[2], GCLK_IO[0] and the XIN/XIN32 oscillator input function. |
| 3 | PA09 | bidirectional | General-purpose I/O with EXTINT[7], SERCOM1 PAD[3], TCC0/WO[3], GCLK_IO[1] and the XOUT/XOUT32 oscillator output function. |
| 4 | PA14 | bidirectional | General-purpose I/O with I2C-capable pad, NMI, ADC AIN[6], AC CMP[0], PTC X[0]/Y[6], SERCOM0 PAD[0], TC1/WO[0] and GCLK_IO[4] muxed functions. |
| 5 | PA15 | bidirectional | General-purpose I/O with I2C-capable pad, EXTINT[1], ADC AIN[7], AC CMP[1], PTC X[1]/Y[7], SERCOM0 PAD[1], TC1/WO[1] and GCLK_IO[5] muxed functions. |
| 6 | PA28/RST | input | Active-low external reset input with internal pull-up, enabled by default after power-up and usable as GPIO PA28 if the reset function is disabled in EXTCTRL. |
| 7 | PA30 | bidirectional | General-purpose I/O that is the SWCLK serial wire debug clock (VDDIO supply), with EXTINT[2], SERCOM1 PAD[0], TC2/WO[0] and GCLK_IO[0] muxed functions. |
| 8 | PA31 | bidirectional | General-purpose I/O that becomes SWDIO serial wire debug data when a debugger is present, with EXTINT[3], SERCOM1 PAD[1], TC2/WO[1] and GCLK_IO[0] muxed functions. |
| 9 | PA24 | bidirectional | General-purpose I/O with EXTINT[4], PTC X[8]/Y[14], SERCOM1 PAD[2] and TCC0/WO[2]; a pull-up through input GPIO mode is recommended if unconnected to avoid extra consumption (<1mA). |
| 10 | PA25 | bidirectional | General-purpose I/O with EXTINT[5], PTC X[9]/Y[15], SERCOM1 PAD[3] and TCC0/WO[3]; a pull-up through input GPIO mode is recommended if unconnected to avoid extra consumption (<1mA). |
| 11 | GND | power_in | Ground pin. |
| 12 | VDDIO/IN/ANA | power_in | Single supply input powering I/O lines, oscillators, internal regulator and analog blocks, 1.62V to 3.63V, with 100nF and 4.7uF decoupling recommended. |
| 13 | PA02 | bidirectional | General-purpose I/O on VDD supply with EXTINT[2], ADC AIN[0], PTC Y[0] and DAC VOUT analog functions. |
| 14 | PA04 | bidirectional | General-purpose I/O with EXTINT[4], ADC/VREFB reference input, ADC AIN[2], AC AIN[0], PTC Y[2], SERCOM0 PAD[2]/PAD[0] and TC1/WO[0] or TCC0/WO[0] muxed functions. |

## Key specifications

| Parameter | Value |

| Manufacturer | Microchip Tech |
| Package | SOIC-14 |
| Category | Embedded Processors & Controllers |
| Pins | 14 |

## 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 | indium tin oxide (ITO) sensor grids. The PTC requires one pin per X-line and one pin per Y-line. In self-capacitance mode, the PTC requires only one pin (Y-line) for each touch sensor. | 800 |
