PY25Q32HB-SSH-IR from PUYA, in a SOP-8. 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	CS#	input	Chip Select (active low). Enables the device when driven low; on rising edge the device latches command completion and enters standby.
2	SO/SIO1	bidirectional	Serial data output for standard 1x SPI (SO); serves as bidirectional IO1 for Dual and Quad SPI / QPI modes.
3	WP#/SIO2	bidirectional	Active-low Write Protect input in Standard/Dual SPI (prevents Status Register writes when combined with SRP bits). Repurposed as bidirectional IO2 in Quad SPI / QPI modes.
4	GND	power_in	Device ground reference (0 V).
5	SI/SIO0	bidirectional	Serial data input for standard 1x SPI (SI); serves as bidirectional IO0 for Dual and Quad SPI / QPI modes.
6	SCLK	input	Serial interface clock input. Supports SPI Mode 0 and Mode 3; data is latched on rising edge and driven on falling edge. Max 133 MHz.
7	HOLD#/RESET#/SIO3	bidirectional	In Standard/Dual SPI, acts as active-low Hardware Reset or HOLD (pause transactions without deselecting the device). Becomes bidirectional IO3 in Quad SPI / QPI modes.
8	VCC	power_in	Device power supply, 2.3 V to 3.6 V (absolute max 4.0 V). Typical read current 8 mA @ 85 MHz; standby 18 uA; deep-power-down 1 uA typical.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`py25q32hb-ssh-ir.step`	122 KB	You want the bare part, or you mark your own boards.
`py25q32hb-ssh-ir-etched.step`	3.1 MB	You want the part with `PY25Q32HB-SSH-IR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 758 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
