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/chip select address input bit 0. Hardwire to VCC (VIH) or GND (VIL) to set the low bit of the 3-bit slave address; recommend a 10kΩ or smaller pull to a known state to avoid capacitive-coupling ambiguity. Internally recognized as VIL if left unconnected. |+| 2 | A1 | input | Device/chip select address input bit 1. Tie to VCC or GND to set the middle bit of the slave-address field; recommend ≤10kΩ pull. Internally recognized as VIL if left floating. |+| 3 | A2 | input | Device/chip select address input bit 2 (MSB of the 3-bit hardware address). Tie to VCC or GND; recommend ≤10kΩ pull. Internally recognized as VIL if left floating. |+| 4 | GND | power_in | Device ground return (0 V reference). |+| 5 | SDA | bidirectional | Serial data line for the 2-wire (I²C-compatible) bus. Open-drain output; requires an external pull-up resistor to VCC and may be wire-ORed with other open-drain devices. |+| 6 | SCL | input | Serial clock input for the 2-wire bus. Rising edge latches data into the EEPROM; falling edge clocks data out. Schmitt-trigger filtered input; supports 1000 kHz at 2.5-5V and 400 kHz at 1.8V. |+| 7 | WP | input | Hardware write-protect input. When tied to VIH/VCC, all programming (write) operations to the EEPROM array are disabled; when tied low (VIL) or left floating, writes are enabled. Read operations are unaffected. Recommend a ≤10kΩ pull to a known state. |+| 8 | VCC | power_in | Main supply input, 1.8V to 5.5V. Decouple locally with a ceramic bypass capacitor (typ. 100 nF) to GND. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | XBLW 24C32N XBLW |+| Package | DIP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `24C32NN`+- `24C32NBN`+- `24C32NMN`+- `24C32NTN`+- `24C32NDN`+- `24C32ND6`+- `24C32NS`++## CAD (KiCad official)++- Symbol: `24C32N`+- Footprint: `Package_DIP:DIP-8_W7.62mm`+- 3D model: DIP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [XBLW 24C32N XBLW datasheet](docs/24c32n-datasheet.pdf) (18 pp, sha256 `e4967cc78153e97f`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
