AT45DB161E-SHD-T

Dialog Semiconductor Adesto Adesto Technologies · NOR FLASH · SOIC-8-208mil

AT45DB161E-SHD-T from Dialog Semiconductor Adesto Adesto Technologies, in a SOIC-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 SI input Serial Input (MOSI). Shifts command, address, and write data into the device; latched on the rising edge of SCK. Ignored while CS is deasserted (high).
2 SCK input Serial Clock. Provides the clock reference for the SPI interface; SI is sampled on the rising edge and SO is driven on the falling edge. Supports up to 85 MHz in RapidS mode.
3 RESET input Active-low hardware reset. A low level terminates any operation in progress and holds the internal state machine in idle; normal operation resumes when driven high. Internal power-on reset covers power-up; tie high externally if unused.
4 CS input Active-low chip select. A high-to-low transition starts an SPI operation; a low-to-high transition ends it. When high, the device is deselected, SO goes high-Z, and SI is ignored (device normally enters standby).
5 WP input Active-low write protect. When asserted, all sectors marked in the Sector Protection Register are protected against program/erase regardless of software protection state; the Sector Protection Register itself becomes non-modifiable. Internally pulled high; may be left floating but tying to VCC is recommended.
6 VCC power_in Device power supply. 2.5 V to 3.6 V for the -SHD- (D) voltage option. Operation outside the valid VCC range may produce spurious results.
7 GND power_in Ground reference for the power supply. Connect to system ground.
8 SO output Serial Output (MISO). Shifts data out of the device on the falling edge of SCK. High-impedance while CS is deasserted (high). Clock-to-output time tV of 6 ns maximum.

Two STEP files. Same geometry, different body top:

File Size Use it when
at45db161e-shd-t.step 122 KB You want the bare part, or you mark your own boards.
at45db161e-shd-t-etched.step 2.4 MB You want the part with AT45DB161E-SHD-T already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 632 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
