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. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Infineon Cypress Semicon |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## 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:++- **Datasheet:** [Infineon Cypress Semicon datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8586186023206596608) (22 pp, sha256 `85968dfdf87dfc9b`, retrieved 2026-09-29, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
