AT24C32N

HGSEMI · EEPROM · DIP-8

AT24C32N from HGSEMI, in a DIP-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 E0 input Slave address input bit 0. Hardware-addressed; internally pulled down to Vss if left floating. Allows up to 8 devices to share the I2C bus.
2 E1 input Slave address input bit 1. Hardware-addressed; internally pulled down to Vss if left floating.
3 E2 input Slave address input bit 2. Hardware-addressed; internally pulled down to Vss if left floating.
4 Vss power_in Ground reference for the Vcc supply.
5 SDA bidirectional Bidirectional serial data line for the I2C bus. Open-drain output; requires an external pull-up resistor and may be wire-OR'ed with other open-drain devices.
6 SCL input I2C serial clock input. Positive-edge clocks data into the device; negative-edge clocks data out. Supports 400 kHz / 1 MHz operation.
7 WCB input Write Control, active-low enable. Tie to Vcc to inhibit all memory write operations; tie to Vss to allow normal writes. Internally pulled down to Vss if left floating.
8 VCC power_in Supply voltage. Operating range 1.7 V to 5.5 V. Read current ~0.2 mA and write current ~0.8 mA typical at 400 kHz.

Two STEP files. Same geometry, different body top:

File Size Use it when
at24c32n.step 271 KB You want the bare part, or you mark your own boards.
at24c32n-etched.step 1.7 MB You want the part with AT24C32N already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 419 faces against 148 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

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

  • Datasheet: HGSEMI datasheet (20 pp, sha256 7e4214ab634175eb, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
