P25Q16SH-UXH-IR

PUYA · NOR FLASH · USON-8(2x3)

P25Q16SH-UXH-IR from PUYA, in a USON-8(2x3). 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 CS# input Chip select input; the CS# notation denotes active-low selection.
2 SO bidirectional Serial data output for 1x I/O and serial data input and output for 4x I/O read mode.
3 WP# bidirectional Write protection input, active low, and serial data input and output for 4x I/O read mode; WP# and HOLD# functions are only available for Standard/Dual SPI.
4 GND power_in Ground of the device.
5 SI bidirectional Serial data input for 1x I/O and serial data input and output for 4x I/O read mode.
6 SCLK input Serial interface clock input.
7 HOLD#/RESET# bidirectional Hardware reset pin, active low, or pauses the device without deselecting it; also serial data input and output for 4x I/O read mode, and available only for Standard/Dual SPI.
8 VCC power_in Power supply of the device, specified for 2.3V to 3.6V.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: P25Q16SH-UXH-IR
  • Footprint: Package_SON:SON-8-1EP_3x2mm_P0.5mm_EP1.4x1.6mm
  • 3D model: USON-8(2x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: p25q16sh-uxh-ir-etched.step / p25q16sh-uxh-ir-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); p25q16sh-uxh-ir.step / p25q16sh-uxh-ir.glb are the bare package body.
