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 | Device address input bit 0. Hardwired to VCC or VSS to set the chip's I2C slave address (combined with E1/E2 allows up to 8 devices on one bus). Internally pulled down to VSS when left floating. |+| 2 | E1 | input | Device address input bit 1. Hardwired to VCC or VSS to set the chip's I2C slave address (combined with E0/E2 allows up to 8 devices on one bus). Internally pulled down to VSS when left floating. |+| 3 | E2 | input | Device address input bit 2. Hardwired to VCC or VSS to set the chip's I2C slave address (combined with E0/E1 allows up to 8 devices on one bus). Internally pulled down to VSS when left floating. |+| 4 | VSS | power_in | Ground reference (0 V) for the device. |+| 5 | SDA | bidirectional | Serial data input/output for the I2C bus. Open-drain output; requires an external pull-up resistor (typical 1.3 kΩ at 2.5-5.5V or 10 kΩ at 1.7V per AC characteristics). |+| 6 | SCL | input | Serial clock input for the I2C bus. Data is clocked in on the positive edge and out on the negative edge. Max clock 400 kHz (1.7-2.5V) or 1 MHz (2.5-5.5V). |+| 7 | WCB | input | Write Control (active low). Tie to VSS to allow normal write operations; tie to VCC to write-protect the entire memory array. Internally pulled down to VSS when left floating. |+| 8 | VCC | power_in | Supply voltage input. Operating range 1.7V to 5.5V (M grade); absolute maximum 6.25V. Typical read current 0.2 mA and write current 0.8 mA at 400 kHz. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | PUYA |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `P24C256B-SSH-MIR`+- `P24C256B-SSH-MIRDP`+- `P24C256B-SSH-MIRMS`+- `P24C256B-SSH-MIRTS`+- `P24C256B-SSH-MIRDN`+- `P24C256B-SSH-MIRUN`+- `P24C256B-SSH-MIRST`++## CAD (KiCad official)++- Symbol: `P24C256B-SSH-MIR`+- 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:** [PUYA datasheet](docs/p24c256b-ssh-mir-datasheet.pdf) (None pp, sha256 `918ff15899ef313c`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
