BR93G66NUX-3TTR

ROHM Semicon · Pre-ordered Chips · VSON-8(2x3)

BR93G66NUX-3TTR 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 CS input Chip select input; must be held low at power ON/OFF, and when low all inputs are cancelled and the device is in standby.
2 SK input Serial clock input; DI is sampled on the rising edge of SK, and the built-in Schmitt trigger has about 0.2V hysteresis.
3 DI input Start bit, ope code, address, and serial data input.
4 DO output Serial data output and READY/BUSY STATUS output; High-Z except during READY/BUSY status and read data output.
5 GND power_in Ground, the 0V reference voltage for all inputs and outputs.
6 ORG input Pin 6 is ORG for the blank pin-assignment code (no 'A') in the part numbering table; the datasheet gives no function or pin description for ORG.
7 DU passive Don't-use terminal; may be set to high, low, or left open.
8 VCC power_in Supply voltage, 1.7V to 5.5V recommended operating range (absolute maximum -0.3 to +6.5V).
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

CAD (KiCad official)

  • Symbol: BR93G66NUX-3TTR
  • 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: br93g66nux-3ttr-etched.step / br93g66nux-3ttr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); br93g66nux-3ttr.step / br93g66nux-3ttr.glb are the bare package body.
