AT45DB641E-SHN-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 pin used for shifting data into the device; all data including command and address sequences are latched on the rising edge of SCK and ignored when the device is deselected (CS deasserted). |
| 2 | SCK | input | Serial Clock pin used to provide clock to the device and control the flow of data to and from the device; command, address, and input data on SI pin are latched on the rising edge of SCK, while output data on SO pin are clocked out on the falling edge of SCK. |
| 3 | RESET | input | Reset pin; a low state will terminate the operation in progress and reset the internal state machine to an idle state; the device will remain in the reset condition as long as a low level is present on this pin and normal operation resumes once the pin is brought back to a high level. |
| 4 | CS | input | Chip Select pin; a high-to-low transition is required to start an operation and a low-to-high transition is required to end an operation; when deasserted (high), the device is placed in standby mode and the SO pin goes to high-impedance state. |
| 5 | SO | tri_state | Serial Output pin used to shift data out from the device; data on the SO pin is always clocked out on the falling edge of SCK and placed in a high-impedance state whenever the device is deselected (CS deasserted). |
| 6 | GND | power_in | Ground reference for the power supply; must be connected to the system ground. |
| 7 | VCC | power_in | Device power supply pin; accepts operating voltage from 1.7V minimum to 3.6V maximum for erase, program, and read operations. |
| 8 | WP | input | Write Protect pin; when asserted (low), all sectors specified for protection by the Sector Protection Register are protected against program and erase operations regardless of software control methods; internally pulled high and may be left floating if hardware protection will not be used. |
