AT93C46DN-SH-T

Microchip · EEPROM · SOIC-8

AT93C46DN-SH-T from Microchip, in a SOIC-8. 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.

CAD (KiCad official)

  • Symbol: AT93C46DN-SH-T
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: at93c46dn-sh-t-etched.step / at93c46dn-sh-t-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at93c46dn-sh-t.step / at93c46dn-sh-t.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
at93c46dn-sh-t.step 122 KB You want the bare part, or you mark your own boards.
at93c46dn-sh-t-etched.step 2.4 MB You want the part with AT93C46DN-SH-T already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 598 faces against 147 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance
