NUC029FAE from Nuvoton Tech, in a TSSOP-20. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | P1.2/RXD/AIN2/ACMP0_P | bidirectional | GPIO P1.2, multiplexed with UART0 receive data (RXD), ADC channel 2 analog input (AIN2), and Comparator0 positive input (ACMP0_P). |
| 2 | P1.3/TXD/AIN3/ACMP0_P | bidirectional | GPIO P1.3, multiplexed with UART0 transmit data (TXD), ADC channel 3 analog input (AIN3), and Comparator0 positive input (as printed in datasheet; likely ACMP0-related analog function). |
| 3 | P1.4/AIN4/ACMP0_N | bidirectional | GPIO P1.4, multiplexed with ADC channel 4 analog input (AIN4) and Comparator0 negative input (ACMP0_N). |
| 4 | P1.5/AIN5/ACMP0_P/AVSS | bidirectional | GPIO P1.5, multiplexed with ADC channel 5 analog input (AIN5) and Comparator0 positive input (ACMP0_P). Pin description table also lists AVSS (analog ground) on this pin. |
| 5 | nRST | input | External reset input: active LOW with an internal pull-up and Schmitt-trigger input. Drive low to reset the chip to its initial state. |
| 6 | P3.2/nINT0/STADC/T0EX/ACMP1_P | bidirectional | GPIO P3.2, multiplexed with external interrupt 0 input (nINT0), ADC external trigger input (STADC), Timer0 external capture/reset trigger input (T0EX), and Comparator1 positive input (ACMP1_P). |
| 7 | P3.4/T0/SDA0/ACMP1_P | bidirectional | GPIO P3.4, multiplexed with Timer0 external event counter input (T0), I2C0 data line (SDA0), and Comparator1 positive input (ACMP1_P). |
| 8 | P3.5/T1/SCL0/ACMP1_P | bidirectional | GPIO P3.5, multiplexed with Timer1 external event counter input (T1), I2C0 clock line (SCL0), and Comparator1 positive input (ACMP1_P). |
| 9 | P5.1/XTAL2 | bidirectional | GPIO P5.1, multiplexed with external 4-24 MHz high-speed crystal (HXT) output pin (XTAL2). |
| 10 | P5.0/XTAL1 | bidirectional | GPIO P5.0, multiplexed with external 4-24 MHz high-speed crystal (HXT) input pin (XTAL1). Schmitt-trigger input on the XTAL1 function. |
| 11 | VSS | power_in | Ground pin for digital circuit. Connect to system ground (0 V). |
| 12 | P2.4/PWM2 | bidirectional | GPIO P2.4, multiplexed with PWM channel 2 output (PWM2). (Datasheet mux description mentions PWM0 output on this pin - likely a typo, function is PWM2.) |
| 13 | P2.5/PWM3 | bidirectional | GPIO P2.5, multiplexed with PWM channel 3 output (PWM3). |
| 14 | P4.6/ICE_CLK | bidirectional | GPIO P4.6, multiplexed with Serial Wired Debugger clock pin (ICE_CLK). |
| 15 | P4.7/ICE_DAT | bidirectional | GPIO P4.7, multiplexed with Serial Wired Debugger data pin (ICE_DAT). |
| 16 | P0.7/SPICLK0 | bidirectional | GPIO P0.7, multiplexed with SPI0 serial clock (SPICLK0). |
| 17 | P0.6/MISO_0 | bidirectional | GPIO P0.6, multiplexed with SPI0 MISO (Master In, Slave Out) data line. |
| 18 | P0.5/MOSI_0 | bidirectional | GPIO P0.5, multiplexed with SPI0 MOSI (Master Out, Slave In) data line. |
| 19 | P0.4/SPISS0/PWM5 | bidirectional | GPIO P0.4, multiplexed with SPI0 slave select (SPISS0) and PWM channel 5 output (PWM5). Datasheet mux row labels SPISS0 as 'SPI1 slave select' but this is a typo - it is SPI0 on the TSSOP-20. |
| 20 | VDD | power_in | Power supply for I/O ports and LDO source for the internal PLL and digital circuit. Operating range 2.5-5.5 V per NUC029FAE DC characteristics. |
