PMS152-S08 from PADAUK Tech, in a SOP-8. 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 | VDD | power_in | Positive power supply, operating range 1.8V to 5.5V (absolute maximum 5.5V). |
| 2 | PA7/X1 | bidirectional | Bit 7 of port A, configurable as input or output with pull-up resistor, or crystal XIN; padier bit 7 must be 0 when used for crystal oscillator to avoid leakage, and the pin can wake the system from sleep. |
| 3 | PA6/X2 | bidirectional | Bit 6 of port A, configurable as input or output with pull-up resistor, or crystal XOUT; padier bit 6 must be 0 when used for crystal oscillator to avoid leakage, and the pin can wake the system from sleep. |
| 4 | PA5/PRSTB/PG2PWM | bidirectional | Bit 5 of port A as input or open-drain output only (sink 10mA), hardware reset input PRSTB, or PWMG2 output; use a 33 ohm series resistor for noise immunity in input mode. |
| 5 | PA3/CIN0-/TM2PWM/PG2PWM | bidirectional | Bit 3 of port A as digital input or two-state output with pull-up, comparator minus input 0, Timer2 PWM output or PWMG2 output; clear padier bit 3 when used as analog input. |
| 6 | PA4/CIN+/CIN1-/INT1A/PG1PWM | bidirectional | Bit 4 of port A as digital input or two-state output with pull-up, comparator plus input or minus input 1, external interrupt 1A (rising and falling edge), or PWMG1 output; clear padier bit 4 when used as analog input. |
| 7 | PA0/CO/PG0PWM/INT0 | bidirectional | Bit 0 of port A as digital input or two-state output with pull-up, comparator output, PWMG0 output, or external interrupt 0 (rising and falling edge); clearing padier bit 0 disables wake-up. |
| 8 | GND | power_in | Ground. |
