C8051F390-A-GMR

SILICON LABS · Microcontroller Units (MCUs/MPUs/SOCs) · QFN-24-EP(4x4)

C8051F390-A-GMR from SILICON LABS, in a QFN-24-EP(4x4). 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 P0.1/IDA0 bidirectional Port 0.1, digital I/O or analog input, also the IDA0 current DAC output.
2 P0.0/VREF bidirectional Port 0.0, digital I/O or analog input, also the external VREF input.
3 GND power_in Ground connection, required; the center pad may optionally be connected to ground also.
4 VDD power_in Power supply voltage.
5 RST/C2CK bidirectional Device reset open-drain output of internal POR or VDD monitor (an external source can reset the device by driving it low for at least 10 μs), and clock signal for the C2 debug interface.
6 P2.4/C2D bidirectional Port 2.4 digital I/O, shared with the bi-directional C2 debug interface data signal C2D on 24-pin packaging.
7 P2.3 bidirectional Port 2.3, digital I/O or analog input.
8 P2.2 bidirectional Port 2.2, digital I/O or analog input.
9 P2.1 bidirectional Port 2.1, digital I/O or analog input.
10 P2.0 bidirectional Port 2.0, digital I/O or analog input.
11 P1.7 bidirectional Port 1.7, digital I/O or analog input.
12 P1.6 bidirectional Port 1.6, digital I/O or analog input.
13 P1.5 bidirectional Port 1.5, digital I/O or analog input.
14 P1.4 bidirectional Port 1.4, digital I/O or analog input.
15 P1.3 bidirectional Port 1.3, digital I/O or analog input.
16 P1.2/IDA1 bidirectional Port 1.2, digital I/O or analog input, also the IDA1 current DAC output.
17 P1.1 bidirectional Port 1.1, digital I/O or analog input.
18 P1.0 bidirectional Port 1.0, digital I/O or analog input.
19 P0.7 bidirectional Port 0.7, digital I/O or analog input.
20 P0.6/CNVSTR bidirectional Port 0.6, digital I/O or analog input, also the ADC0 external convert start or IDA0 update source input.
21 P0.5 bidirectional Port 0.5, digital I/O or analog input; the Crossbar always assigns UART RX0 to this pin.
22 P0.4 bidirectional Port 0.4, digital I/O or analog input; the Crossbar always assigns UART TX0 to this pin.
23 P0.3/XTAL2 bidirectional Port 0.3, digital I/O or analog input, also the external clock output (crystal/resonator excitation driver) or external clock input for CMOS, capacitor or RC oscillator configurations.
24 P0.2/XTAL1 bidirectional Port 0.2, digital I/O or analog input, also the external oscillator return for a crystal or resonator.
25 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
