NSP171A from Nuvoton 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 | BP00 | bidirectional | General input/output pin, individually settable as input (optional pull-high) or output, shared with ICPCLK and used as SCL for the host 2-I/O protocol. |
| 2 | VSS | power_in | Negative power supply for oscillation, uP and peripherals, tied to ground. |
| 3 | VDD | power_in | Positive power supply, operating range 2.0 to 5.5 V, with 4.7uF and 0.1uF decoupling capacitors placed close to the chip. |
| 4 | PWM+ | output | PWM driver positive output to drive the speaker directly, rated for +250 mA into 8 ohm. |
| 5 | PWM- | output | PWM driver negative output to drive the speaker directly, rated for -250 mA into 8 ohm. |
| 6 | VSS_SPK | power_in | Negative power supply for the speaker driver, connected to ground. |
| 7 | /RESET | input | IC reset input, active low, with a 0.1uF capacitor to ground in the typical application. |
| 8 | BP01 | bidirectional | General input/output pin, individually settable as input (optional pull-high) or output, shared with ICPDATA and used as SDA for the host 2-I/O protocol. |
