P25Q16SH-SSH-IR

PUYA · NOR FLASH · SOP-8

P25Q16SH-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 input, active low. Enables the device when driven low and puts the outputs in high-impedance when driven high. Must be toggled between each command.
2 SO/SIO1 bidirectional Serial data output (SO) in Standard SPI mode (1x I/O). Acts as bidirectional I/O line SIO1 in Dual/Quad SPI and QPI modes.
3 WP#/SIO2 bidirectional Write protect input (active low) in Standard/Dual SPI modes; asserts hardware protection of the status register per SRP bits. Acts as bidirectional I/O line SIO2 in Quad SPI and QPI modes.
4 GND power_in Ground reference for the device. All signal voltages are referenced to this pin.
5 SI/SIO0 bidirectional Serial data input (SI) in Standard SPI mode (1x I/O). Acts as bidirectional I/O line SIO0 in Dual/Quad SPI and QPI modes.
6 SCLK input Serial interface clock input. Data on SI/SIOx is latched on the rising edge and data on SO/SIOx is shifted out on the falling edge. Supports SPI Mode 0 and Mode 3, up to 133 MHz.
7 HOLD#/RESET#/SIO3 bidirectional Hardware Reset (active low) or Hold input to pause the device without deselecting it, in Standard/Dual SPI modes. Acts as bidirectional I/O line SIO3 in Quad SPI and QPI modes.
8 VCC power_in Power supply input, 2.3V to 3.6V. Should be decoupled with a 100nF ceramic capacitor placed close to the pin.
