93LC46B

Microchip Tech · EEPROM · SOIC-8

93LC46B 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 Chip Select: a high level selects the device and a low level deselects it into standby, and CS must be low for 250 ns minimum (TCSL) between consecutive instructions.
2 CLK input Serial Data Clock that synchronizes communication, clocking opcode, address and data in (and data out) on the positive edge; it is a don't-care when CS is low.
3 DI input Serial Data Input used to clock in the START bit, opcode, address and data synchronously with CLK.
4 DO tri_state Serial Data Output that outputs data in READ mode (TPD after the CLK positive edge), provides READY/BUSY status during ERASE/WRITE, and is HIGH-Z when status is not available.
5 Vss power_in Ground.
6 NC unconnected No Connect.
7 NC unconnected No Connect.
8 Vcc power_in Power supply, +2.5V to +6.0V operating range with an absolute maximum of 7.0V.

CAD (KiCad official)

  • Symbol: 93LC46B
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: 93lc46b-etched.step / 93lc46b-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 93lc46b.step / 93lc46b.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Microchip Tech datasheet (12 pp, sha256 d3dc4146cf5515c3, retrieved 2026-10-28, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
