FM25Q16A-SOB-T-G

FUDAN MICRO · NOR FLASH · SOP-8-208mil

FM25Q16A-SOB-T-G from FUDAN MICRO, in a SOP-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 input that enables device operation when low and disables when high, placing output pins in high impedance state.
2 DO (DQ1) bidirectional Data Output (DQ1) - output in standard SPI mode or bidirectional DQ1 in dual/quad SPI modes; driven to high impedance when device is deselected (CS# high).
3 WP# (DQ2) bidirectional Write Protect Input (DQ2) - active-low input that prevents status register writes in standard mode or serves as DQ2 for bidirectional dual/quad I/O when QE bit is set in Status Register-2.
4 VSS power_in Ground - power supply ground connection required for proper device operation.
5 DI (DQ0) bidirectional Data Input (DQ0) - bidirectional input in standard SPI mode or DQ0 in dual/quad SPI modes; input data is sampled on the rising edge of CLK.
6 CLK input Serial Clock Input - provides timing for all serial input and output operations; supports clock frequencies up to 104 MHz in FAST_READ mode.
7 HOLD# (DQ3) bidirectional Hold Input (DQ3) - active-low input that pauses device operation while CS# is low in standard mode or serves as DQ3 for bidirectional dual/quad I/O when QE bit is set.
8 VCC power_in Power Supply - positive supply voltage (2.3V to 3.6V); bypass capacitor recommended near this pin.
