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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | HGSEMI |+| Package | MSOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `HG24C32MM/TR`+- `HG24C32MMHG24C32N`+- `HG24C32MMHG24C32M/TR`+- `HG24C32MMHG24C32MT/TR`+- `HG24C32MMHG24C32DQ3/TR`+- `HG24C32MMHG24C32M5/TR`++## CAD (KiCad official)++- Symbol: `HG24C32MM`+- Footprint: `Package_SO:MSOP-8_3x3mm_P0.65mm`+- 3D model: MSOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [HGSEMI datasheet](docs/hg24c32mm-datasheet.pdf) (20 pp, sha256 `a83336a282838dca`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
