HC32F002C4PZ-TSSOP20TR

XHSC · Microcontrollers (MCU/MPU/SOC) · TSSOP-20

HC32F002C4PZ-TSSOP20TR from XHSC, in a TSSOP-20. 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	PD04/AIN4/LVDIN2	bidirectional	Port PD04 with ADC input AIN4, LVD monitor input LVD_IN2, and alternate functions GTIM_CH0, LPUART1_TXD and SPI_SCK; the ADC input range is 0 to Vref.
2	PD05/AIN5	bidirectional	Port PD05 with ADC input AIN5 and alternate functions LPUART1_TXD, ATIM3_CH0A and SPI_MISO; the ADC input range is 0 to Vref.
3	PD06/AIN6	bidirectional	Port PD06 with ADC input AIN6 and alternate functions LPUART1_RXD, GTIM_ETR and SPI_MOSI; the ADC input range is 0 to Vref.
4	RESETB/PA00	input	Active-low reset input (CMOS, with a non-disconnectable weak pull-up of about 80 kΩ) that is also port PA00; the datasheet specifies VIH 0.7VCC to VCC+0.3 V and VIL -0.3 to 0.3VCC V, with a 3 µs filtered-pulse width.
5	AIN7/PA01	bidirectional	Port PA01 with ADC input AIN7 and alternate functions LPUART0_RXD, I2C_SDA, GTIM_TOGP, HCLK_OUT and EXTCLK (external clock input, 1 to 16 MHz); the ADC input range is 0 to Vref.
6	AIN8/PA02	bidirectional	Port PA02 with ADC input AIN8 and alternate functions LPUART0_TXD, I2C_SCL, GTIM_TOGN and LVD_OUT; the ADC input range is 0 to Vref.
7	AVSS/DVSS	power_in	Analog and digital ground; all ground pins must be kept within 50 mV of each other, and the pin must be connected to the external supply system.
8	PA04	bidirectional	General-purpose I/O port PA04 with alternate functions GTIM_TOGP, LVD_OUT and SPI_NSS.
9	AVCC/DVCC	power_in	Analog and digital supply, 1.7 to 5.5 V; AVCC should be the same supply as DVCC, with no more than 300 mV difference during power-up and normal operation, and a decoupling capacitor placed close to the pin.
10	LVDIN0/PA03	bidirectional	Port PA03 with LVD monitor input LVD_IN0 and alternate functions GTIM_CH2, SPI_NSS, CTRIM_ETR and CTRIM_TOG.
11	PB05/AIN9	bidirectional	Port PB05 with ADC input AIN9 and alternate functions I2C_SDA, ATIM3_BK, CTRIM_ETR and CTRIM_TOG; this pin is a higher-drive port on the TSSOP20 package.
12	PB04/AIN10	bidirectional	Port PB04 with ADC input AIN10 and alternate functions I2C_SCL, ATIM3_CH2B and LPUART0_CTS; this pin is a higher-drive port on the TSSOP20 package.
13	PC03/LVDIN1/ExRef	bidirectional	Port PC03 with LVD monitor input LVD_IN1, ADC external reference input ExRef, and alternate functions ATIM3_CH2A, ATIM3_CH0B and LPUART0_RTS; this pin is a higher-drive port on the TSSOP20 package.
14	PC04/AIN0	bidirectional	Port PC04 with ADC input AIN0 and alternate functions ATIM3_CH0B, ATIM3_CH1B and TCLK_OUT.
15	PC05	bidirectional	General-purpose I/O port PC05 with alternate functions SPI_SCK, GTIM_CH3 and ATIM3_ETR; it has no ADC function on this package.
16	PC06/AIN1	bidirectional	Port PC06 with ADC input AIN1 and alternate functions SPI_MOSI, ATIM3_CH0A and LPUART1_RTS.
17	PC07/SWDIO	bidirectional	Port PC07 used as the SWD data pin (SWDIO) with alternate functions SPI_MISO, ATIM3_CH1A and LPUART0_RXD.
18	PD01/SWCLK	input	Port PD01 used as the SWD clock pin (SWCLK) with alternate functions GTIM_ETR, ATIM3_BK and LPUART0_TXD.
19	PD02/AIN2	bidirectional	Port PD02 with ADC input AIN2 and alternate functions GTIM_CH2, ATIM3_CH2A and LPUART1_CTS.
20	PD03/AIN3	bidirectional	Port PD03 with ADC input AIN3 and alternate functions GTIM_CH1, ATIM3_CH1A and LPUART1_RXD.
