HG24C32MM

HGSEMI · EEPROM · MSOP-8

HG24C32MM from HGSEMI, in a MSOP-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. Combined with E1/E2 to give up to 8 devices on the same I²C bus. Internally pulled down to Vss if left floating.
2 E1 input Slave address input bit 1. Combined with E0/E2 for hardware address selection. Internally pulled down to Vss if left floating.
3 E2 input Slave address input bit 2. Combined with E0/E1 for hardware address selection. Internally pulled down to Vss if left floating.
4 Vss power_in Ground reference for Vcc supply.
5 SDA bidirectional I²C serial data input/output. Open-drain; requires external pull-up. Wire-OR compatible with other open-drain devices.
6 SCL input I²C serial clock input. Positive edge clocks data in; negative edge clocks data out. Supports up to 400 kHz (1 MHz in high-speed mode).
7 WCB input Write Control, active low. Tie to Vss to allow normal writes; tie to Vcc to inhibit all memory write operations. Internally pulled down to Vss if left floating.
8 VCC power_in Supply voltage input, 1.7 V to 5.5 V.

  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: hg24c32mm-etched.step / hg24c32mm-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hg24c32mm.step / hg24c32mm.glb are the bare package body.

Provenance

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

  • Datasheet: HGSEMI datasheet (20 pp, sha256 a83336a282838dca, 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).
