BR25H320NUX-5ACTR

ROHM Semicon · EEPROM · VSON-8(2x3)

BR25H320NUX-5ACTR from ROHM Semicon, in a VSON-8(2x3). 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 CSB input Chip select input for the SPI bus; when HOLD status is entered, CSB must be held Low, and setting CSB High during HOLD resets the IC so communication cannot be restarted.
2 SO output Serial data output; it goes to high impedance (High-Z) during HOLD status, and the datasheet gives IOLMAX 10 mA and IOHMAX -10 mA limits for this pin.
3 WPB input Write protect input; when WPEN = 1 and WPB is Low, the Write Status Register command is disabled, while WRITE, WRID and LID remain writable.
4 GND power_in All input/output reference voltage, 0 V.
5 SI input Serial data input for the SPI bus; its value is Don't Care during HOLD status.
6 SCK input Serial clock input for the SPI bus, with clock frequency up to 20 MHz (Max) stated in the key specifications.
7 HOLDB input Hold input; pulling it Low while SCK is Low pauses serial communication (HOLD status) and setting it High while SCK is Low releases HOLD.
8 VCC power_in Power supply, with the operating supply voltage range given as 1.7 V to 5.5 V.
9 EXP-PAD passive Exposed pad (from the footprint; not named in the datasheet pin table).

  • Symbol: BR25H320NUX-5ACTR
  • Footprint: Package_SON:SON-8-1EP_3x2mm_P0.5mm_EP1.4x1.6mm
  • 3D model: VSON-8(2x3), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.9 mm nominal QFN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
  • 3D model files: br25h320nux-5actr-etched.step / br25h320nux-5actr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); br25h320nux-5actr.step / br25h320nux-5actr.glb are the bare package body.
