# FT24C64A-ESR-T

**FMD Fremont Micro Devices** · EEPROM · SOP-8

FT24C64A-ESR-T from FMD Fremont Micro Devices, in a SOP-8. 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. Hardwire to VIH or VIL to set the chip select address; internally recognized as VIL if left unconnected. |
| 2 | A1 | input | Device address input bit 1. Hardwire to VIH or VIL to set the chip select address; internally recognized as VIL if left unconnected. |
| 3 | A2 | input | Device address input bit 2. Hardwire to VIH or VIL to set the chip select 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 I/O for I2C data; requires external pull-up (typ. 1.3 kOhm to VCC per AC test conditions) and can be wire-OR'd with other open-drain devices. |
| 6 | SCL | input | Serial clock input. Data is latched on the rising edge and clocked out on the falling edge. Up to 1 MHz at 2.5-5V VCC, 400 kHz at 1.8V VCC. |
| 7 | WP | input | Write protect input. Programming is allowed when WP is unconnected or tied to VIL; all programming is disabled when WP is tied to VIH or VCC. Read operations are unaffected by WP. |
| 8 | VCC | power_in | Supply voltage, 1.8V to 5.5V. Absolute maximum 8V. Typical read/write current 0.4 mA / 2.0 mA at 5.0V; standby current <1 uA. |

## CAD (KiCad official)

- Symbol: `FT24C64A-ESR-T`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOP-8 (KiCad packages3D, STEP)
- 3D model files: `ft24c64a-esr-t-etched.step` / `ft24c64a-esr-t-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ft24c64a-esr-t.step` / `ft24c64a-esr-t.glb` are the bare package body.
