W25Q128JWSIQ TR

Winbond Elec · NOR FLASH · SOIC-8-208mil

W25Q128JWSIQ TR from Winbond Elec, in a SOIC-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 Chip select input (active low) that selects the device and enables instruction acceptance; when high, device is deselected and output pins are high-impedance.
2 DO (IO1) output Data output in standard SPI mode on the falling edge of CLK; functions as bidirectional IO1 in dual and quad SPI modes.
3 /WP (IO2) input Write protect input (active low) that prevents status register writes when used with SRP bit in standard/dual SPI modes; functions as bidirectional IO2 in quad SPI mode when QE bit is set to 1.
4 GND power_in Ground; 0V reference.
5 DI (IO0) input Data input in standard SPI mode sampled on the rising edge of CLK; functions as bidirectional IO0 in dual and quad SPI modes.
6 CLK input Serial clock input providing timing for serial input and output operations; maximum 133 MHz for quad I/O (EBh) instructions, 104 MHz for other instructions.
7 /HOLD or /RESET (IO3) input Hold input (active low) in standard/dual SPI modes to pause operation while /CS is low; becomes bidirectional IO3 in quad SPI mode when QE bit is set; hardware reset function only available on SOIC-16 and TFBGA packages.
8 VCC power_in Power supply input; operating voltage range 1.7V to 1.95V at -40°C to +85°C for industrial grade per section 9.2.
