FM25040B-GTR

Infineon Cypress Semicon · FRAM · SOIC-8

FM25040B-GTR from Infineon Cypress Semicon, 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 Active LOW chip select input that activates the device; device enters standby mode and ignores other inputs when CS is HIGH.
2 SO tri_state Serial output driven on the falling edge of SCK during read operations; remains tri-stated at all other times including when HOLD is LOW.
3 WP input Active LOW write protect input that prevents all write operations including Status Register modification when LOW; must be tied to VDD if not used.
4 VSS power_in Power supply ground reference; must be connected to the system ground.
5 SI input Serial input pin sampled on the rising edge of SCK; must always be driven to a valid logic level to meet IDD specifications.
6 SCK input Serial clock input that synchronizes all I/O activity; operating frequency may be 0 to 20 MHz and may be interrupted at any time.
7 HOLD input HOLD input used to interrupt memory operations without aborting them; when LOW with SCK LOW, operation is suspended; must be tied to VDD if not used.
8 VDD power_in Power supply input with operating voltage range of 4.5 V to 5.5 V; provides power for all internal device circuits.

CAD (KiCad official)

  • Symbol: FM25040B-GTR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: fm25040b-gtr-etched.step / fm25040b-gtr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); fm25040b-gtr.step / fm25040b-gtr.glb are the bare package body.

Provenance

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