AT25SF041B-SSHD-T

Dialog Semiconductor · NOR FLASH · SOIC-8

AT25SF041B-SSHD-T from Dialog Semiconductor, in a SOIC-8. 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: Asserting the CS pin selects the device, and a high-to-low transition is required to start an operation while a low-to-high transition ends it.
2 SO (IO1) bidirectional SERIAL OUTPUT: Data on the SO pin is clocked out on the falling edge of SCK, and the pin is high-impedance whenever the device is deselected.
3 WP (IO2) bidirectional WRITE PROTECT: The WP pin controls the hardware locking feature and is internally pulled high, with external connection to VCC recommended whenever possible.
4 GND power_in GROUND: The ground reference for the power supply, which must be connected to the system ground.
5 SI (IO0) bidirectional SERIAL INPUT: Data on the SI pin is always latched in on the rising edge of SCK and is ignored whenever the device is deselected.
6 SCK input SERIAL CLOCK: This pin provides the clock to the device, latching SI input on the rising edge and clocking SO output on the falling edge.
7 HOLD (IO3) bidirectional HOLD: The HOLD pin temporarily pauses serial communication without deselecting or resetting the device, and is internally pulled high with external connection to VCC recommended whenever possible.
8 VCC power_in DEVICE POWER SUPPLY: The VCC pin supplies the source voltage to the device, specified as 2.7 V to 3.6 V for this ordering code.
