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 VIH or VIL to set the slave address; internally recognized as VIL if left unconnected. |+| 2 | A1 | input | Device/chip select address input bit 1. Hardwire to VIH or VIL to set the slave address; internally recognized as VIL if left unconnected. |+| 3 | A2 | input | Device/chip select address input bit 2. Hardwire to VIH or VIL to set the slave address; internally recognized as VIL if left unconnected. |+| 4 | GND | power_in | Ground reference for the device. |+| 5 | SDA | bidirectional | Serial data line. Bi-directional open-drain output; must be pulled to VCC with an external resistor. Can be wired-OR with other open-drain devices on the I2C bus. |+| 6 | SCL | input | Serial clock input. Rising edge latches data into the EEPROM, falling edge clocks data out. Supports 400 kHz at 1.8V and up to 1 MHz at 2.5-5.0V. |+| 7 | WP | input | Write protect input. When tied to VIH or VCC, all programming (write) operations are disabled; when left unconnected or tied to VIL, writes are enabled. Read operations are unaffected by WP. |+| 8 | VCC | power_in | Supply voltage input. Operating range 1.8V to 5.5V. Standby current < 1 µA. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | FMD Fremont Micro Devices |+| Package | SOP-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `FT24C256A-ESR-T`+- `FT24C256A-ESR-TP`+- `FT24C256A-ESR-TEM`+- `FT24C256A-ESR-TET`+- `FT24C256A-ESR-TEU`++## CAD (KiCad official)++- Symbol: `FT24C256A-ESR-T`+- 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:** [FMD Fremont Micro Devices datasheet](docs/ft24c256a-esr-t-datasheet.pdf) (16 pp, sha256 `265daf0b084f49aa`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
