Zetta · NOR FLASH · USON-8(2x3)
ZD25LD40BEIGR from Zetta, 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, active low, enables device for SPI communication when pulled low |
| 2 | SO | tri_state | Serial output data for 1x I/O mode or SIO1 for 2x I/O dual mode, goes high-impedance when CS# is high |
| 3 | WP# | input | Write protection input, active low, also functions as SIO2 in dual I/O mode, hardware controls block protect and status register protect bits |
| 4 | GND | power_in | Ground, 0V reference voltage for the device |
| 5 | SI | tri_state | Serial input data for 1x I/O mode or SIO0 for 2x I/O dual mode, accepts command and address bytes in SPI communication |
| 6 | SCLK | input | Serial clock input for SPI communication, maximum frequency 85 MHz for most operations, 33 MHz for standard READ mode |
| 7 | NC | unconnected | Not connected, leave floating or connect to ground |
| 8 | VCC | power_in | Power supply input, operating voltage range 1.65V to 2.0V |
| 9 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |

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)
