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 | CSB | input | Active-low chip select input. Drive low to select the device and frame an SPI transaction; drive high to deselect and place SO in high impedance. Referenced to Vcc; VIH >= 0.7*Vcc (>=0.8*Vcc below 1.7V). |+| 2 | SO | output | Serial data output (MISO). Data is shifted out MSB first on the falling edge of SCK. High-impedance when CSB is high or HOLDB is asserted. Drive strength: VOH >= Vcc-0.2 V at IOH = -2 mA (2.5-5.5 V). |+| 3 | WPB | input | Active-low hardware write-protect input. When low, the WRSR (Write Status Register) command is inhibited, locking the block-protection bits BP0/BP1 and preventing changes to write protection. |+| 4 | GND | power_in | Ground reference (0 V) for all inputs, outputs, and internal circuitry. |+| 5 | SI | input | Serial data input (MOSI). Op-code, address, and write data are shifted in MSB first on the rising edge of SCK. Setup time tDIS = 5 ns min at Vcc >= 4.5 V. |+| 6 | SCK | input | Serial clock input. Supports SPI modes (CPOL,CPHA) = (0,0) and (1,1) up to 20 MHz max at Vcc >= 4.5 V (5 MHz max at 1.7-2.5 V, 3 MHz max at 1.6-1.7 V). |+| 7 | HOLDB | input | Active-low hold input. Pulling HOLDB low while CSB is low pauses the current SPI transaction and forces SO to high impedance; the transaction resumes when HOLDB returns high. Allows the master to service higher-priority devices on a shared bus. |+| 8 | Vcc | power_in | Positive supply, 1.6 V to 5.5 V. Recommended bypass capacitor 0.1 uF to GND. Typical read current 0.1 uA standby, 2.0 mA read, 0.6 mA write at 5 V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | ROHM |+| Package | SOIC-8 |+| Category | Memory |+| Pins | 8 |++## Ordering variants++- `BR25G256FJ-3GE2`+- `BR25G256FJ-3GE2BR25G256F-3GE2`+- `BR25G256FJ-3GE2BR25G256FVT-3GE2`+- `BR25G256FJ-3GE2BR25G256-3`++## CAD (KiCad official)++- Symbol: `BR25G256FJ-3GE2`+- 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:** [ROHM datasheet](docs/br25g256fj-3ge2-datasheet.pdf) (37 pp, sha256 `6e0b88fc30c2ef44`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
