25LC160C-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, a high level deselects it and forces Standby mode, and a low-to-high transition after a valid write sequence starts an internal write cycle. |
| 2 | SO | tri_state | Serial data output that shifts data out after the falling edge of SCK and goes to the high-impedance state when the device is deselected. |
| 3 | WP | input | Write-protect pin that, together with the WPEN STATUS register bit, disables writes to the nonvolatile STATUS register bits when low and has no effect on a write cycle already in progress. |
| 4 | VSS | power_in | Ground reference pin for the device. |
| 5 | SI | input | Serial data input that 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 updates after its falling edge. |
| 7 | HOLD | input | Hold input that pauses serial communication when pulled low while SCK is low, must be held high when unused, and tri-states SO when lowered. |
| 8 | VCC | power_in | Supply voltage pin; for the 25LC160C it is 2.5-5.5V per the device selection table. |
