Winbond Elec · NOR FLASH · SOIC-8-208mil
W25Q64JWSSIM 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 | SPI Chip Select (active low). When high, the device is deselected and DO/IO pins are high-impedance; when low, the device is selected and instructions can be issued. Must transition high->low after power-up before any new instruction is accepted; a pull-up to VCC is recommended. |
| 2 | DO (IO1) | bidirectional | Serial Data Output for Standard SPI (unidirectional DO); becomes bidirectional IO1 for Dual/Quad SPI and QPI modes. Data is clocked out on the falling edge of CLK in standard SPI. |
| 3 | /WP (IO2) | bidirectional | Write Protect input (active low) for Standard/Dual SPI: when low with SRP0=1, blocks Status Register writes and hardware-protects the memory array per BP bits. Reassigned as bidirectional IO2 when QE bit of Status Register-2 is set for Quad I/O / QPI. |
| 4 | GND | power_in | Device ground reference (0 V). Connect directly to system ground plane. |
| 5 | DI (IO0) | bidirectional | Serial Data Input for Standard SPI (unidirectional DI); becomes bidirectional IO0 for Dual/Quad SPI and QPI modes. Instructions, addresses and data are latched on the rising edge of CLK. |
| 6 | CLK | input | Serial Clock input. Provides the timing for all serial input/output operations; supports up to 133 MHz Quad I/O SPI clock (equivalent 532 MHz effective data rate in Quad I/O). CMOS input referenced to VCC. |
| 7 | /HOLD or /RESET (IO3) | bidirectional | Multi-function pin. In Standard/Dual SPI with QE=0: acts as /HOLD (active low) to pause an active serial operation, or optionally as software-configurable /RESET (via Status Register-3 HOLD/RST bit); DO goes Hi-Z and DI/CLK are ignored while /HOLD is low. When QE=1 (Quad enabled), becomes bidirectional IO3 for Quad SPI / QPI transfers. |
| 8 | VCC | power_in | Power supply input. 1.7 V to 1.95 V (nominal 1.8 V). Active current ~1 mA, power-down current <0.1 uA. Decouple with a 100 nF capacitor close to the pin. |
