AT45DB641E-MHN2B-T from RENESAS, in a UDFN-8(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 in all command, address and data bits, latched on the rising edge of SCK, and is ignored whenever the device is deselected (CS deasserted). |
| 2 | SCK | input | Serial Clock controls data flow to and from the device, with input on SI 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; drive it high externally if unused. |
| 4 | CS | input | Active-low Chip Select selects the device when asserted, while deasserting it deselects the device into standby (not Deep Power-Down) and puts SO in high impedance; a high-to-low transition starts an operation and a low-to-high transition ends it. |
| 5 | WP | input | Active-low Write Protect protects all sectors specified in the Sector Protection Register against program and erase regardless of the Enable Sector Protection command; it is internally pulled high and may float if hardware protection is unused, though connecting it to VCC is recommended. |
| 6 | VCC | power_in | Device power supply (1.7 V to 3.6 V); operation at invalid VCC voltages can produce spurious results and must not be attempted. |
| 7 | GND | power_in | Ground reference for the power supply, which must be connected to system ground. |
| 8 | SO | output | 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 (CS deasserted). |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
