25AA320AT-I

Microchip Tech · EEPROM · SOIC-8

25AA320AT-I 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 Chip Select input: a low level selects the device, a high level deselects it and forces Standby mode with SO in high-impedance.
2 SO tri_state Serial Data Output: data is shifted out after the falling edge of SCK, and the pin is high-impedance when the device is deselected or HOLD is low.
3 WP input Write-Protect: with WPEN set, WP low disables writes to the nonvolatile bits of the STATUS register; when WP is high all functions operate normally.
4 VSS power_in Ground.
5 SI input Serial Data Input: receives instructions, addresses and data, latched on the rising edge of SCK.
6 SCK input Serial Clock Input: synchronizes communication, with SI latched on the rising edge and SO updated after the falling edge (maximum 10 MHz).
7 HOLD input Hold Input: pulling it low while SCK is low pauses serial communication without resetting the sequence, and it must be held high when unused.
8 VCC power_in Supply Voltage: 1.8V to 5.5V for 25AA320A, with an absolute maximum of 6.5V.

CAD (KiCad official)

  • Symbol: 25AA320AT-I
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: 25aa320at-i-etched.step / 25aa320at-i-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); 25aa320at-i.step / 25aa320at-i.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
