93LC56BT-I from Microchip, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | CS | input | Chip Select. Active-high; a low level deselects the device and forces it into Standby mode. Must be low for TCSL = 250 ns minimum between consecutive instructions. VIH = 0.7*VCC (VCC<2.7V) or 2.0V (VCC>=2.7V). |
| 2 | CLK | input | Serial Clock. Synchronizes communication between master device and 93XX device. Opcodes, address and data bits are clocked in on the positive edge of CLK; data bits are also clocked out on positive edge. FCLK max = 2 MHz (2.5V<=VCC<5.5V) or 1 MHz (1.8V<=VCC<2.5V). |
| 3 | DI | input | Data In. Used to clock in a Start bit, opcode, address and data synchronously with the CLK input on rising edge. Input setup time TDIS = 100 ns min (2.5V<=VCC<5.5V). |
| 4 | DO | tri_state | Data Out. Outputs data synchronously with CLK input during READ (TPD after positive edge of CLK). Also provides Ready/Busy status information during erase/write cycles when CS is brought high after the minimum TCSL low time. Enters High-Z on falling edge of CS. |
| 5 | VSS | power_in | Ground reference for all signals and the internal supply return. |
| 6 | NC | unconnected | No internal connection on the 'B' version. This pin position is used as the ORG (organization select) pin on the 'C' version of the family; on the 93LC56B the x16 organization is fixed and no ORG pin function is present. |
| 7 | NC | unconnected | No internal connection. May be left floating. |
| 8 | VCC | power_in | Power supply input. Operating range 2.5V to 5.5V for the 93LC family. Absolute maximum 7.0V. Standby current typ 1 uA (I-temp). |
