PY25Q64HA-SUH-IR from PUYA, in a SOP-8-208mil. 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	Active-low chip select. Drive low to enable the device for SPI/QPI transactions; drive high to deselect and place SO/IO lines in high-impedance.
2	SO/IO1	bidirectional	Serial data output in 1x I/O (Standard SPI) mode. Acts as bidirectional data line IO1 in Dual/Quad SPI and QPI modes.
3	WP#/IO2	bidirectional	Active-low write protect input in Standard/Dual SPI (protects status-register writes when combined with SRP bits). Serves as bidirectional data line IO2 in Quad SPI and QPI modes.
4	GND	power_in	Ground reference for the device. Connect to system ground.
5	SI/IO0	bidirectional	Serial data input in 1x I/O (Standard SPI) mode. Acts as bidirectional data line IO0 in Dual/Quad SPI and QPI modes.
6	SCLK	input	Serial interface clock input. Sampled on rising/falling edges depending on SPI mode (Mode 0 and Mode 3 supported). Max 133 MHz for most instructions.
7	HOLD#/RESET#/IO3	bidirectional	Active-low hardware reset input, or HOLD# to pause the device without deselecting it (function is configurable). In Quad SPI / QPI modes this pin becomes bidirectional data line IO3.
8	VCC	power_in	Main power supply, 2.7 V to 3.6 V. Decouple with a 100 nF ceramic capacitor to GND close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`py25q64ha-suh-ir.step`	122 KB	You want the bare part, or you mark your own boards.
`py25q64ha-suh-ir-etched.step`	2.8 MB	You want the part with `PY25Q64HA-SUH-IR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 697 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.
