Hard-wired to VCC or GND to select one of up to 8 devices sharing the I2C bus. Internally biased to logic low if left floating. |+| 2 | A1 | input | Device address input bit 1. Hard-wired to VCC or GND to select one of up to 8 devices sharing the I2C bus. Internally biased to logic low if left floating. |+| 3 | A2 | input | Device address input bit 2. Hard-wired to VCC or GND to select one of up to 8 devices sharing the I2C bus. Internally biased to logic low if left floating. |+| 4 | GND | power_in | Ground reference for the device. |+| 5 | SDA | bidirectional | Bidirectional I2C serial data line. Open-drain output; requires an external pull-up resistor to VCC. May be wire-ORed with other open-drain/open-collector devices. |+| 6 | SCL | input | I2C serial clock input. Positive edges clock data into the EEPROM; negative edges clock data out. Supports 100 kHz, 400 kHz, and 1 MHz bus speeds. |+| 7 | WP | input | Hardware write protect. Tie to GND for normal read/write operation; tie to VCC to write-protect the full 128 Kbit array. |+| 8 | VCC | power_in | Positive supply voltage input. Single-supply operation up to 1 MHz interface speed. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `AT24C128AM/TR`+- `AT24C128AMAN`+- `AT24C128AMM/TR`+- `AT24C128AMADQ/TR`++## CAD (KiCad official)++- Symbol: `AT24C128AM`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/at24c128am-datasheet.pdf) (15 pp, sha256 `ed9771daf6536261`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
