93LC56 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: a high level selects the device and a low level deselects it and forces Standby mode, and CS must be low for 250 ns minimum (TCSL) between consecutive instructions. |
| 2 | CLK | input | Serial Data Clock that synchronizes communication with the master, clocking opcode, address and data in on the positive edge, with a clock frequency of up to 2 MHz at VCC ≥ 4.5V and 1 MHz otherwise. |
| 3 | DI | input | Serial Data Input used to clock in the Start bit, opcode, address and data synchronously with the CLK input. |
| 4 | DO | tri_state | Serial Data Output that outputs data synchronously with CLK (TPD max 400 ns) in Read mode, gives Ready/Busy status during erase/write, is High-Z otherwise, and needs a pull-up resistor to read the Ready signal if status is checked after the cycle. |
| 5 | VSS | power_in | Ground. |
| 6 | ORG | input | Memory Configuration: tied to VCC selects x16 organization and tied to VSS selects x8, and it may be floated only for clock speeds of 1 MHz or less in x16 organization. |
| 7 | NU | unconnected | Not Utilized. |
| 8 | VCC | power_in | Power supply, with DC characteristics specified for VCC = 2.5V to 5.5V and an absolute maximum of 6.5V. |
