FT24C256A-ETR-T

FMD Fremont Micro Devices · EEPROM · TSSOP-8

FT24C256A-ETR-T from FMD Fremont Micro Devices, in a TSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 A0 input Device address input that is hardwired to VIH or VIL and is read as VIL if left unconnected.
2 A1 input Device address input that is hardwired to VIH or VIL and is read as VIL if left unconnected.
3 A2 input Device address input that is hardwired to VIH or VIL and is read as VIL if left unconnected.
4 GND power_in Ground.
5 SDA bidirectional Serial data line, bi-directional with an open-drain output that can be wire-ORed and is typically pulled high by an external resistor.
6 SCL input Serial clock input where the rising edge latches data into the EEPROM and the falling edge clocks data out.
7 WP input Write protect input that allows programming when left unconnected or at VIL and disables all programming when connected to VIH or VCC, with reads unaffected.
8 VCC power_in Supply voltage, 1.8V to 5.5V.
