M93S66-WMN6TP from STMicroelectronics, in a SO-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 | S | input | Chip select input; low deselects the device (Q high-impedance, standby unless a write is in progress) and high selects it for active power mode. |
| 2 | C | input | Serial clock input; instructions, addresses and data on D are latched on its rising edge, and Q changes after the rising edge, with a maximum frequency of 2 MHz. |
| 3 | D | input | Serial data input that receives instructions, addresses and data to be written, latched on the rising edge of C. |
| 4 | Q | tri_state | Serial data output that shifts data out on the rising edge of C, provides the ready/busy status during programming, and is high-impedance when S is low. |
| 5 | VSS | power_in | Ground, the reference for the VCC supply voltage. |
| 6 | W | input | Write protect input; when held low writes to the memory are disabled while other operations remain enabled, and it must be driven high or low and not left floating. |
| 7 | PRE | input | Protection register enable input that must be driven high before and during instructions accessing the Protection Register. |
| 8 | VCC | power_in | Supply voltage of 2.5 V to 5.5 V that must be stable during operation, with a 10 nF to 100 nF decoupling capacitor recommended close to the VCC/VSS pins. |
