W25X40CLUXIG TR

Winbond Elec · NOR FLASH · USON8-EP(2x3)

W25X40CLUXIG TR from Winbond Elec, in a USON8-EP(2x3). 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 input, active low. Drive low to select the device and initiate an instruction; drive high to deselect and force DO/IO0/IO1 to high impedance. Must transition high-to-low after power-up before the first instruction; may require an external pull-up to VCC.
2 DO (IO1) bidirectional Serial Data Output in Standard SPI mode (unidirectional output, sampled on falling edge of CLK). Acts as bidirectional IO1 in Dual I/O SPI mode. High impedance when /CS is high or /HOLD is low.
3 /WP input Write Protect input, active low. Used with Status Register SRP/TB/BP bits to hardware-protect all or a portion of the memory array from Write Status Register instructions.
4 GND power_in Ground reference for the device.
5 DI (IO0) bidirectional Serial Data Input in Standard SPI mode (unidirectional input, sampled on rising edge of CLK). Acts as bidirectional IO0 in Dual I/O SPI mode.
6 CLK input SPI Serial Clock input. Provides timing for serial input (sampled on rising edge) and serial output (driven on falling edge). Supports clock frequencies up to 104 MHz.
7 /HOLD input Hold input, active low. When brought low while /CS is low, DO goes high impedance and DI/CLK are ignored, allowing the SPI bus to be shared with another device without deselecting the flash. Return high to resume the paused operation.
8 VCC power_in Power supply. Single 2.3V to 3.6V supply. Active current ~1mA typ, power-down current <1uA typ.
