AT24C32M

HGSEMI · EEPROM · SOP-8

AT24C32M from HGSEMI, in a SOP-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. Sets the least-significant bit of the I2C device address (A0), allowing hardware selection between up to 8 devices on the same bus. Internally pulled down to Vss when left floating.
2 E1 input Slave address input bit 1. Sets the middle bit of the I2C device address (A1). Internally pulled down to Vss when left floating.
3 E2 input Slave address input bit 2. Sets the most-significant bit of the hardware-selectable I2C device address (A2). Internally pulled down to Vss when left floating.
4 Vss power_in Ground reference for the Vcc supply. Connect to the system 0 V rail.
5 SDA bidirectional I2C serial data line. Bidirectional open-drain pin used for command, address, and data transfer. Requires an external pull-up resistor to Vcc (typical 1.3 kΩ at 2.5-5.5 V, 10 kΩ at 1.7 V). VOL = 0.4 V max at IOL = 2.1 mA.
6 SCL input I2C serial clock input. Positive edge clocks data in and negative edge clocks data out. Maximum clock frequency 100 kHz / 400 kHz / 1 MHz depending on Vcc; Schmitt-triggered with input filtering for noise suppression.
7 WCB input Write Control input, active low enable for writes. Tie to Vss to allow normal write operations; tie to Vcc to inhibit all writes to the memory array. Internally pulled down to Vss when left floating (writes enabled).
8 VCC power_in Positive supply voltage input. Operating range 1.7 V to 5.5 V. Recommended local decoupling of 100 nF to Vss close to the pin.

CAD (KiCad official)

  • Symbol: AT24C32M
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: at24c32m-etched.step / at24c32m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); at24c32m.step / at24c32m.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
at24c32m.step 122 KB You want the bare part, or you mark your own boards.
at24c32m-etched.step 1.7 MB You want the part with AT24C32M already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 427 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

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.
