BR25G128NUX-3TR

ROHM Semicon · EEPROM · VSON-8(2x3)

BR25G128NUX-3TR 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; set CSB LOW to start a command and CSB HIGH to end it, and the IC is reset if CSB goes HIGH during HOLD status.
2 SO output Serial data output, updated on the falling edge of SCK and placed in High-Z when the device is in HOLD status.
3 WPB input Write protect input; setting WPB LOW prohibits the write status register command, subject to the WPEN bit setting.
4 GND power_in All input/output reference voltage, 0V.
5 SI input Opcode, address and serial data input, latched on the rising edge of SCK.
6 SCK input Serial clock input, with a maximum SCK frequency of 20MHz at 4.5V to 5.5V.
7 HOLDB input Hold input; pulling it LOW while SCK is LOW suspends command communication (HOLD status).
8 Vcc power_in Power source, operating from 1.6V to 5.5V with an absolute maximum of -0.3 to +6.5V.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: BR25G128NUX-3TR
  • 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: br25g128nux-3tr-etched.step / br25g128nux-3tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); br25g128nux-3tr.step / br25g128nux-3tr.glb are the bare package body.

Provenance

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

  • Datasheet: ROHM Semicon datasheet (35 pp, sha256 711842223453aad1, retrieved 2026-10-30, tier: manufacturer)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-haiku-5-5 (text), consensus claude-sonnet-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
