AT25SF041B-SSHB-B

Dialog/Adesto · NOR FLASH · SOIC-8

AT25SF041B-SSHB-B from Dialog/Adesto, 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 is active low: a high-to-low transition starts an operation and a low-to-high transition ends it, and a 10k Ohm pull-up from CS to VCC is recommended for power-up sequencing.
2 SO (IO1) bidirectional Serial output is clocked out on the falling edge of SCK and is high-impedance when the device is deselected; it serves as IO1 in the dual and quad read commands.
3 WP (IO2) bidirectional Write protect is internally pulled high and can be left floating, and it is asserted low to protect the Status Registers only when QE = 0 and SRP1/SRP0 = 0/1; when QE = 1 it is used as IO2 and must not be used for write protection.
4 GND power_in Ground reference for the power supply, to be connected to system ground.
5 SI (IO0) bidirectional Serial input carries all command, address and data input and is latched on the rising edge of SCK, and it becomes IO0 in the dual and quad output read commands and is ignored while the device is deselected.
6 SCK input Serial clock: SI is latched in on the rising edge of SCK and SO is clocked out on the falling edge of SCK.
7 HOLD (IO3) bidirectional HOLD pauses serial communication without resetting the clock sequence while CS is low, is internally pulled high and can be left floating, and becomes IO3 when QE = 1.
8 VCC power_in Device power supply pin that supplies the source voltage to the device, specified at 2.7 V to 3.6 V for this ordering code.
