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. Hardware slave-address bit used to select the device on a shared 2-wire bus; tie directly to VCC or GND. Corresponds to bit 1 of the I2C device address byte. |+| 2 | A1 | input | Device Address Input bit 1. Hardware slave-address bit used to select the device on a shared 2-wire bus; tie directly to VCC or GND. Corresponds to bit 2 of the I2C device address byte. |+| 3 | A2 | input | Device Address Input bit 2. Hardware slave-address bit used to select the device on a shared 2-wire bus; tie directly to VCC or GND. Corresponds to bit 3 of the I2C device address byte. |+| 4 | GND | power_in | Ground reference for the power supply. Connect to the system ground. |+| 5 | SDA | bidirectional | Serial Data. Open-drain bidirectional I/O for the I2C bus; requires an external pull-up (<=10 kOhm) to VCC. Can be wire-ORed with other open-drain devices on the same bus. |+| 6 | SCL | input | Serial Clock input from the bus master. Input data on SDA is latched on the rising edge of SCL and output data changes on the falling edge. Must be driven high or pulled high with an external pull-up when the bus is idle. |+| 7 | WP | input | Write Protect. Active high: tie to GND for normal write operations; tie to VCC to inhibit all writes to the memory array. Internally pulled down (weakly) to GND when floating; datasheet recommends driving to a known state. |+| 8 | VCC | power_in | Device power supply, 1.7V to 5.5V (2.5V to 5.5V required for 1MHz Fast Mode Plus). Operation outside the specified VCC range may produce spurious results. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Zetta |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `ZD24C256A-SSGMBSSGMB`++## CAD (KiCad official)++- Symbol: `ZD24C256A-SSGMB`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Zetta datasheet](docs/zd24c256a-ssgmb-datasheet.pdf) (26 pp, sha256 `18ebc71abd08daef`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
