AT25FF161A-SSHN-T

Adesto Technologies · NOR FLASH · SOIC-8

AT25FF161A-SSHN-T from Adesto Technologies, 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, active low: asserting CS 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 (I/O1) bidirectional Serial output clocked out on the falling edge of SCK, becoming I/O1 in multi-I/O read modes and high-impedance when the device is deselected.
3 WP (I/O2) bidirectional Write protect input, internally pulled high and recommended to be connected to VCC, becoming I/O2 when the QE bit is set.
4 GND power_in Ground reference for the power supply; should be connected to the system ground.
5 SI (I/O0) bidirectional Serial input latched on the rising edge of SCK, becoming I/O0 in multi-I/O read modes and ignored while the device is deselected.
6 SCK input Serial clock: command, address and input data on SI are latched on the rising edge, and output data on SO is clocked out on the falling edge.
7 HOLD/RESET (I/O3) bidirectional Pauses serial communication while asserted with CS low, or acts as a device RESET per Status Register 3 bit 7, internally pulled high and becoming I/O3 when QE is set.
8 VCC power_in Supplies the source voltage to the device; operation at invalid VCC voltages may produce spurious results and should not be attempted.
