# M93C56-RMN6TP

**STMicroelectronics** · EEPROM · SOIC-8

M93C56-RMN6TP from STMicroelectronics, 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 | S | input | Chip Select input; must be driven to VSS during power-up and is brought low between instructions, and a rising edge on S starts each instruction. |
| 2 | C | input | Serial Clock input with a maximum clock rate of 2 MHz; data is sampled on the rising edge and C must be held low when S rises. |
| 3 | D | input | Serial Data input that carries the start bit, op-code, address and data bits, sampled on the rising edge of C. |
| 4 | Q | output | Serial Data output that shifts out read data and gives the READY/BUSY status (Q=0 busy, Q=1 ready) and is high impedance when the device is not selected. |
| 5 | VSS | power_in | Ground reference for the device. |
| 6 | ORG | input | Organization Select: connected to VSS selects x8, and left unconnected or tied to VCC selects x16, and it should be set to VSS or VCC in Standby for minimum current. |
| 7 | DU | unconnected | Don't Use pin reserved for ST test sequences; it may be left unconnected or connected to VCC or VSS. |
| 8 | VCC | power_in | Supply voltage of 1.8 V to 5.5 V for M93C56-R, with a 10 nF to 100 nF decoupling capacitor recommended close to the VCC/VSS pins. |
