HG24LC64M

HGSEMI · EEPROM · SOP-8

HG24LC64M 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 A0 input Device address input bit 0. Hard-wired to VCC or GND to set one of the three user-selectable device address bits (up to eight devices per two-wire bus).
2 A1 input Device address input bit 1. Hard-wired to VCC or GND to select the device on the two-wire bus.
3 A2 input Device address input bit 2. Hard-wired to VCC or GND to select the device on the two-wire bus.
4 GND power_in Ground reference for the device.
5 SDA bidirectional Serial data line for the two-wire (I2C) interface. Open-drain output; requires an external pull-up resistor. Bi-directional for reads and writes.
6 SCL input Serial clock input for the two-wire (I2C) interface. Data is latched into the EEPROM on the positive edge and clocked out on the negative edge. Supports 1 MHz at 5V and 400 kHz at 1.8/2.5/2.7V.
7 WP input Write Protect. Tie to GND for normal read/write operation. Tie to VCC to hardware-write-protect the full 64K array.
8 VCC power_in Positive supply voltage, 1.8V to 5.5V operating range (absolute max 6.5V).

CAD (KiCad official)

  • Symbol: HG24LC64M
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: hg24lc64m-etched.step / hg24lc64m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); hg24lc64m.step / hg24lc64m.glb are the bare package body.

Provenance

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

  • Datasheet: HGSEMI datasheet (14 pp, sha256 4178d79f29490d4d, 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).
