93AA66BT-I from Microchip Tech, in a SOT-23-6. 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 | DO | output | Data Out outputs read data synchronously with CLK (TPD after the positive CLK edge) and shows Ready/Busy status during erase and write cycles when CS is brought high. |
| 2 | VSS | power_in | Ground reference pin for the device. |
| 3 | DI | input | Data In clocks in the Start bit, opcode, address and data synchronously with the CLK input. |
| 4 | CLK | input | Serial Clock synchronizes host communication; opcodes, address and data are clocked in on the positive CLK edge and CLK is a don't care while CS is low. |
| 5 | CS | input | A high level selects the device and a low level deselects it into Standby mode; CS must be low for 250 ns minimum (TCSL) between consecutive instructions. |
| 6 | VCC | power_in | Power supply pin; the Device Selection Table lists the 93AA66B VCC range as 1.8V-5-5V (printed text), and WRAL operation requires VCC of at least 4.5V. |
