25AA010A-I from Microchip Tech, in a PDIP-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 | Chip Select input: a low level selects the device, and a high level deselects it and forces it into Standby mode. |
| 2 | SO | output | Serial Data Output: data is shifted out after the falling edge of the serial clock during a read, and SO goes to high impedance when the device is deselected. |
| 3 | WP | input | Write-Protect input: when low, all writes to the array or STATUS register are disabled while other operations function normally. |
| 4 | VSS | power_in | Ground reference pin for the device. |
| 5 | SI | input | Serial Data Input: receives instructions, addresses and data, which are latched on the rising edge of the serial clock. |
| 6 | SCK | input | Serial Clock input: synchronizes communication, with SI latched on its rising edge and SO updated after its falling edge. |
| 7 | HOLD | input | Hold input: when pulled low while the device is selected, it pauses serial communication without resetting the sequence, and it must be held high when not used. |
| 8 | VCC | power_in | Supply voltage; the 25AA010A is specified for VCC = 1.8V to 5.5V. |
