# M93C46-WDW6TP

**STMicroelectronics** · EEPROM · TSSOP-8

M93C46-WDW6TP from STMicroelectronics, in a TSSOP-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; a pull-down resistor on S ensures no device is selected if the bus master leaves S in high impedance. |
| 2 | C | input | Serial Clock input for the MICROWIRE bus, operating at 2 MHz or less. |
| 3 | D | input | Serial Data input. |
| 4 | Q | output | Serial Data output, high impedance when the device is not selected. |
| 5 | VSS | power_in | Ground. |
| 6 | ORG | input | Organization Select input that configures the memory array as bytes (x8) or words (x16). |
| 7 | DU | unconnected | Don't use: reserved for ST test sequences, may be left unconnected or connected to VCC or VSS. |
| 8 | VCC | power_in | Supply voltage, 2.5 V to 5.5 V for M93Cx6-W devices. |
