Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | CS | input | Chip Select (active LOW). When HIGH, the device enters low-power standby mode, ignores other inputs, and tri-states the output. A falling edge on CS internally activates the SCK signal and must occur before every opcode. |+| 2 | SO | output | Serial Output (MISO). Driven during a read and tri-stated at all other times, including when HOLD is LOW. Data transitions on the falling edge of SCK. |+| 3 | WP | input | Write Protect (active LOW). Prevents write operations to the Status Register when WPEN=1. Must be tied to VDD if not used. |+| 4 | VSS | power_in | Ground reference for the device. Must be connected to system ground. |+| 5 | SI | input | Serial Input (MOSI). All data is input on this pin, sampled on the rising edge of SCK. Should always be driven to a valid logic level to meet IDD specs. May be tied to SO for a single-pin data interface. |+| 6 | SCK | input | Serial Clock. All I/O activity is synchronized to this clock. Inputs are latched on the rising edge and outputs occur on the falling edge. Clock frequency 0 to 20 MHz; may be interrupted at any time. |+| 7 | HOLD | input | HOLD (active LOW). When LOW, suspends the current SPI operation; device ignores transitions on SCK and CS. Transitions must occur while SCK is LOW. Must be tied to VDD if not used. |+| 8 | VDD | power_in | Power supply input to the device. Operating range 2.7 V to 3.65 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Infineon |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `FM25CL64B-GTRG`+- `FM25CL64B-GTRGTR`+- `FM25CL64B-GTRDG`+- `FM25CL64B-GTRDGTR`++## CAD (KiCad official)++- Symbol: `FM25CL64B-GTR`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOIC-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Infineon datasheet](docs/fm25cl64b-gtr-datasheet.pdf) (21 pp, sha256 `7c6df2f70b3e907d`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
