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 slave-address setting bit 0. Hardwire to VCC or GND to set A0 of the 7-bit I2C slave address (allows up to 8 devices on one bus). If left floating, an internal pull-down forces this bit to 0. |+| 2 | E1 | input | Device slave-address setting bit 1. Hardwire to VCC or GND to set A1 of the 7-bit I2C slave address. If left floating, an internal pull-down forces this bit to 0. |+| 3 | E2 | input | Device slave-address setting bit 2. Hardwire to VCC or GND to set A2 of the 7-bit I2C slave address. If left floating, an internal pull-down forces this bit to 0. |+| 4 | GND | power_in | Ground reference for the device (0 V). |+| 5 | SDA | bidirectional | I2C serial data input/output. Open-drain, requires an external pull-up to VCC; can be wire-OR'd with other open-drain devices. Schmitt-triggered noise-suppressed input; output VOL <= 0.2 V at IOL = 1.5 mA (VCC = 1.7 V). |+| 6 | SCL | input | I2C serial clock input. Data is clocked in on the rising edge and clocked out on the falling edge. Supports up to 400 kHz below VCC = 2.5 V and up to 1 MHz from 2.5 V to 5.5 V. |+| 7 | WCB | input | Write control (active-low enable). Tie to GND to allow normal writes; tie to VCC to inhibit all writes to the memory array. Internally pulled down (5 M-ohm typ., 30 k-ohm max) so a floating pin defaults to write-enabled. |+| 8 | VCC | power_in | Supply voltage input. -MI grade: 1.7 V to 5.5 V, -40 C to +85 C. Standby current <= 1.0 uA (VCC = 3.3 V, 85 C); read current <= 400 uA; write current <= 1.6 mA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | PUYA |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++Same part, different packaging or reel option.++- `P24C128D-SSH-MIR`++## CAD (KiCad official)++- Symbol: `P24C128D-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/p24c128d-ssh-mir-datasheet.pdf) (25 pp, sha256 `4e7c982781c7caea`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
