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. When CS is high the device is selected; when low, DI is ignored and DO is high-impedance. Also used to end an instruction and (after being brought high following a write) to poll Ready/Busy on DO. |+| 2 | SK | input | Serial Data Clock. Synchronizes communication between the master and the EEPROM. Instructions, addresses and data on DI are latched on the rising edge of SK; DO is also clocked out on the rising edge of SK. |+| 3 | DI | input | Serial Data Input. Receives instructions, addresses and data into the device. Data is latched on the rising edge of SK. |+| 4 | DO | tri_state | Serial Data Output. Shifts read data out on the rising edge of SK following a read command. Also outputs the Ready/Busy status of the part when CS is brought high after being low for at least tCS during an erase/write cycle. High-impedance when device is not selected. |+| 5 | GND | power_in | Ground reference for the power supply. Connect to system ground. |+| 6 | ORG | input | Internal Organization select. Tie to VCC for x16 organization (64 words of 16 bits); tie to GND for x8 organization (128 words of 8 bits). If left floating an internal 1 MOhm pull-up selects x16. |+| 7 | NC | unconnected | No Connect. Leave floating or tie as convenient; no internal function. |+| 8 | VCC | power_in | Device power supply, 1.8V to 5.5V. Operating outside this range may produce spurious behavior. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Microchip |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `AT93C46DN-SH-TN-SH-T`+- `AT93C46DN-SH-TN`+- `AT93C46DN-SH-TP`+- `AT93C46DN-SH-TY`+- `AT93C46DN-SH-TMA`+- `AT93C46DN-SH-TU`++## CAD (KiCad official)++- Symbol: `AT93C46DN-SH-T`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Microchip datasheet](docs/at93c46dn-sh-t-datasheet.pdf) (36 pp, sha256 `a48a4419bbd78dbb`, retrieved 2026-08-17, tier: manufacturer)+- **Extractor:** `ds2sf` (Claude).
