25AA512T-I from Microchip Tech, 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 | A low level on this pin selects the device, while a high level deselects it and forces it into Standby mode. |
| 2 | SO | output | Data is shifted out on this pin after the falling edge of the serial clock during a read cycle, and SO goes high-impedance when the device is deselected. |
| 3 | WP | input | When WP is low and WPEN is high, writing to the nonvolatile bits in the STATUS register is disabled while all other operations function normally. |
| 4 | VSS | power_in | Ground reference pin for the device. |
| 5 | SI | input | Receives instructions, addresses and data, which are latched on the rising edge of the serial clock. |
| 6 | SCK | input | Synchronizes communication with the host: SI is latched on the rising clock edge and SO is updated after the falling clock edge. |
| 7 | HOLD | input | Pulling HOLD low while SCK is low suspends serial communication without resetting the sequence, and it must be held high when this function is not used. |
| 8 | VCC | power_in | Supply voltage pin; the device VCC range is 1.8-5.5V per the Device Selection Table. |
