MX25R4035FZUIL0TR

MXIC(Macronix) · NOR FLASH · USON-8(2x3)

MX25R4035FZUIL0TR from MXIC(Macronix), in a USON-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 for the serial interface, as listed in the pin description table (CS# is the only function given for this pin).
2 SO/SIO1 bidirectional Serial Data Output for 1 x I/O mode, and Serial Data Input & Output (SIO1) for 4 x I/O read mode.
3 WP#/SIO2 bidirectional Write Protection, active low, or Serial Data Input & Output (SIO2) for 4 x I/O read mode; the internal pull-up stays active while the pin is not physically connected in the system, and is disabled if the system connects to it.
4 GND power_in Ground.
5 SI/SIO0 bidirectional Serial Data Input for 1 x I/O mode, and Serial Data Input & Output (SIO0) for 4 x I/O read mode.
6 SCLK input Clock Input for the serial interface.
7 RESET#/SIO3 bidirectional Hardware Reset pin, active low, or Serial Data Input & Output (SIO3) for 4 x I/O read mode; for this part number (MX25R4035FZUIL0, RESET# option) the pin is RESET#, and the internal pull-up stays active while the pin is not physically connected.
8 VCC power_in Power Supply; the operating range for this part is 1.65V-3.6V per the ordering information.
9 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).

  • Footprint: Package_SON:SON-8-1EP_3x2mm_P0.5mm_EP1.4x1.6mm
  • 3D model: USON-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: mx25r4035fzuil0tr-etched.step / mx25r4035fzuil0tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); mx25r4035fzuil0tr.step / mx25r4035fzuil0tr.glb are the bare package body.
