Mysentech · Float Level Senors · QFN-24-EP(4x4)

MCP61S from Mysentech, in a QFN-24-EP(4x4). 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 PA3 bidirectional General-purpose I/O port PA3. Standard TC-level I/O; input signal must not exceed VDD. Alternate functions: USART1_RX, USART2_SCK, SPI1_NSS; additional function: ADC1_VIN[2].
2 PA14/NRST bidirectional General-purpose I/O port PA14. Standard TC-level I/O. Alternate functions: SWCLK, USART1_TX, SPI1_SCK. When RCC_SYSCFG SFT_NRST_RMP bit is set to 1, PA14 is remapped as NRST external reset input; reset low pulse must be at least 4 µs.
3 PB0/OSCIN bidirectional General-purpose I/O port PB0, also serves as external HSE clock input (OSCIN, up to 48 MHz). Standard TC-level I/O. Alternate function: USART2_SCK; additional function: ADC1_VIN[1].
4 PA1 bidirectional General-purpose I/O port PA1. Standard TC-level I/O; input signal must not exceed VDD. Alternate functions: USART1_SCK, USART2_TX, I2C1_SDA, SPI1_MOSI.
5 VDD power_in Main digital power supply. Operating range 2.5 V to 5.5 V (typ. 3.3 V); absolute max 5.8 V. Decouple to GND near the pin.
6 PA15 bidirectional General-purpose I/O port PA15. Standard TC-level I/O. Alternate functions: SPI1_NSS, TIM1_CH3N, SPI1_MOSI, TIM3_CH3; additional function: ADC1_VIN[6].
7 GND power_in Digital ground reference. Tie to system ground plane.
8 PA0 bidirectional General-purpose I/O port PA0. Standard TC-level I/O. Alternate functions: SPI1_NSS, USART1_RX, TIM1_CH3N, I2C1_SCL, TIM3_CH3.
9 PA4 bidirectional General-purpose I/O port PA4. Standard TC-level I/O. Alternate functions: TIM1_BKIN, I2C1_SDA, TIM3_CH4.
10 PA5 bidirectional General-purpose I/O port PA5. Standard TC-level I/O. Alternate functions: SPI1_SCK, TIM1_CH1N, I2C1_SCL.
11 GND power_in Digital ground reference. Tie to system ground plane.
12 VDDA power_in Analog power supply for the CAP-AFE and ADC. Same 2.5-5.5 V range as VDD; typically tied to VDD through an isolation filter for best analog performance.
13 GNDA power_in Analog ground reference for the CAP-AFE and ADC. Tie to the system ground plane (typically star-connected to GND).
14 C0N input Channel 0 capacitive sensor input, negative side of the differential pair. Connect together with C0P to the measured differential capacitor plates.
15 C0P input Channel 0 capacitive sensor input, positive side of the differential pair. Connect together with C0N to the measured differential capacitor plates (typ. sensor capacitance range 1-1000 pF).
16 VT output Temperature voltage output; a negative-temperature-coefficient voltage used with an external ADC (10-bit is sufficient) for approximate temperature measurement. Recommend a 1 nF external capacitor to GND for a ~1 ms settling time.
17 C1N input Channel 1 capacitive sensor input, negative side of the differential pair. Typically used for the reference capacitor of the ratiometric measurement.
18 C1P input Channel 1 capacitive sensor input, positive side of the differential pair. Typically used with C1N for the reference capacitor of the ratiometric measurement.
19 NC unconnected No connect. Leave floating or tie to GND per PCB practice.
20 RUP bidirectional External resistance pin for the CAP-AFE. Requires an external pull-up resistor (recommended 10 kΩ) to VDD per the typical application circuit.
21 PA10 bidirectional General-purpose I/O port PA10. Standard TC-level I/O. Alternate functions: SPI1_MISO, TIM1_CH3, TIM1_CH2, MCO (main clock output), USART1_TX.
22 PA13 bidirectional General-purpose I/O port PA13. Standard TC-level I/O. Alternate functions: SWDIO (serial-wire debug data), USART1_RX, USART2_RX, I2C1_SCL, SPI1_MISO.
23 PA2 bidirectional General-purpose I/O port PA2. Standard TC-level I/O. Alternate functions: TIM1_CH2N, SPI1_MISO, TIM3_CH2; additional function: ADC1_VIN[5].
24 PA12 bidirectional General-purpose I/O port PA12. Standard TC-level I/O. Alternate function: USART1_TX; additional function: ADC1_VIN[3].
