25AA02E48T-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 | Chip Select input: a low level selects the device, while a high level deselects it and forces Standby mode, and a low level is required after power-up before any sequence is initiated. |
| 2 | SO | tri_state | Serial Data Output: data is shifted out after the falling edge of SCK during a read, and the pin goes to high-impedance when the device is deselected or HOLD is low. |
| 3 | WP | input | Hardware write-protect input: when low, all writes to the array or STATUS register are disabled while other operations function normally, and the write enable latch is reset. |
| 4 | VSS | power_in | Ground reference for the device. |
| 5 | SI | input | Serial Data Input: receives instructions, addresses and data, latched on the rising edge of SCK. |
| 6 | SCK | input | Serial Clock input that synchronizes communication: SI is latched on its rising edge and SO is updated after its falling edge. |
| 7 | HOLD | input | Hold input used to pause serial communication while selected: it must be brought low while SCK is low, must be held high when unused, and tri-states SO when pulled low. |
| 8 | VCC | power_in | Supply voltage, specified for operation from 1.8V to 5.5V. |
