AT45DB041E-MHN-T from Adesto Technologies, in a UDFN-8-EP(5x6). 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 | SI | input | Serial Input shifts command, address and data into the device and is latched on the rising edge of SCK, and it is ignored while CS is deasserted. |
| 2 | SCK | input | Serial Clock controls data flow to and from the device, with input latched on the rising edge and output on SO clocked out on the falling edge of SCK. |
| 3 | RESET | input | Active-low reset terminates the operation in progress and holds the internal state machine idle while low, and it should be driven high externally if unused. |
| 4 | CS | input | Active-low Chip Select selects the device, a high-to-low transition starts an operation, and when deasserted the device is deselected (normally standby) and SO goes high-impedance. |
| 5 | WP | input | Active-low Write Protect protects the sectors set in the Sector Protection Register against program and erase, is internally pulled high, and should preferably be tied to VCC if unused. |
| 6 | VCC | power_in | Device power supply pin for the 1.65V to 3.6V supply, where operation at invalid VCC voltages may produce spurious results. |
| 7 | GND | power_in | Ground reference for the power supply, to be connected to system ground. |
| 8 | SO | tri_state | Serial Output shifts data out of the device on the falling edge of SCK and is in a high-impedance state whenever the device is deselected. |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
