# AT93C46N

**HGSEMI** · EEPROM · DIP-8

AT93C46N from HGSEMI, in a DIP-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 | Chip Select; must be pulled high before issuing a command on DI and pulled low for a minimum of 250 ns (tCS) before polling Ready/Busy. |
| 2 | SK | input | Serial Data Clock used with DI to clock instructions and data, up to 2 MHz at 4.5V-5.5V. |
| 3 | DI | input | Serial Data Input for the start bit, op code, address and data bits, clocked in with SK. |
| 4 | DO | tri_state | Serial Data Output that shifts out read data and indicates Ready/Busy status, and goes high impedance when CS is low. |
| 5 | GND | power_in | Ground. |
| 6 | ORG | input | Internal Organization select: connect to Vcc for x16 mode or ground it for x8 mode. |
| 7 | NC | unconnected | No Connect. |
| 8 | Vcc | power_in | Power Supply, 1.8V to 5.5V operating range with 6.25V maximum operating voltage. |

## CAD (KiCad official)

- Symbol: `AT93C46N`
- Footprint: `Package_DIP:DIP-8_W7.62mm`
- 3D model: DIP-8 (KiCad packages3D, STEP)
- 3D model files: `at93c46n-etched.step` / `at93c46n-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `at93c46n.step` / `at93c46n.glb` are the bare package body.
