# 93AA46A-I

**Microchip Tech** · Pre-ordered Chips · SOIC-8

93AA46A-I 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 | A high level selects the device, and CS must be low for 250 ns minimum (TCSL) between consecutive instructions. |
| 2 | CLK | input | Serial clock that synchronizes data; opcodes, address and data bits are clocked in and out on its positive edge. |
| 3 | DI | input | Data In clocks in the Start bit, opcode, address and data synchronously with the CLK input. |
| 4 | DO | output | Data Out outputs read data synchronously with CLK (TPD after the positive edge) and provides Ready/Busy status during erase and write cycles. |
| 5 | VSS | power_in | Ground reference for the device. |
| 6 | NC | unconnected | ORG pin is not connected on the 93AA46A, which is always x8 organization. |
| 7 | NC | unconnected | No internal connection. |
| 8 | VCC | power_in | Power supply input; the 93AA46A operates from 1.8 V to 5.5 V. |

## CAD (KiCad official)

- Symbol: `93AA46A-I`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `93aa46a-i-etched.step` / `93aa46a-i-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `93aa46a-i.step` / `93aa46a-i.glb` are the bare package body.
