25LC512T-E

Microchip Tech · EEPROM · SOIC-8

25LC512T-E from Microchip Tech, in a SOIC-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 CS input A low level selects the device, and a high level deselects it and forces it into Standby mode, with SO going high-impedance.
2 SO output Transfers data out of the 25LC512, with data shifted out after the falling edge of the serial clock.
3 WP input With WPEN set, a low level disables writes to the nonvolatile STATUS register bits, and hardware write protection is disabled when WP is high or WPEN is low.
4 VSS power_in Ground reference for the device.
5 SI input Receives instructions, addresses and data, latched on the rising edge of SCK.
6 SCK input Synchronizes communication with the host; SI is latched on the rising edge and SO updates after the falling edge.
7 HOLD input Pulling it low while SCK is low pauses serial communication without resetting the sequence, and it must be held high when this function is not used.
8 VCC power_in Supply voltage, specified from 2.5V to 5.5V in the electrical characteristics.

CAD (KiCad official)

  • Symbol: 25LC512T-E
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: 25lc512t-e-etched.step / 25lc512t-e-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 25lc512t-e.step / 25lc512t-e.glb are the bare package body.
