| Parameter | W25Q80DVSSIG | P25Q80SH-SSH-IR | Engineering note |
|---|---|---|---|
| Package and exact order code | W25Q80DVSSIG: SS package code, 8-pin SOIC 208-mil | P25Q80SH-SSH-IR: SS package code, 8-lead SOP 150-mil, tape and reel | The target footprint is narrower and is not PCB drop-in compatible with the source. The exact Puya order code for SOP8 208-mil is P25Q80SH-SUH-IR. |
| Supply range | W25Q80DV: 2.7 V to 3.6 V | P25Q80SH: 2.3 V to 3.6 V | The target has a wider operating supply range. |
| Clock frequency | 104 MHz for dual/quad and other supported commands; 50 MHz for READ (03h) | 120 MHz for FREAD and selected program/erase commands; 104 MHz for dual/quad reads; 55 MHz for READ (03h) | The target is faster at the published operating points, but frequency equivalence does not make the package or command-level firmware behavior identical. |
| Security registers | Three 256-byte OTP security registers | Three 512-byte OTP security registers | Register size differs; firmware must not assume identical payload capacity. |
| Unique ID | 64-bit unique ID | 128-bit unique ID | Firmware that reads, logs, hashes or whitelists a 64-bit ID must be reviewed. |
| Pin 7 function | /HOLD only on the 8-pin SOIC package | HOLD# / RESET# multiplexed function | Pin numbers match the standard 8-lead SPI NOR arrangement, but the added reset capability does not make the physical package compatible. |
FAE documentary review accepted only as a functional alternative for the exact Winbond W25Q80DVSSIG and Puya P25Q80SH-SSH-IR order codes. Both are 8 Mbit SPI NOR devices with 256-byte pages, 4 KiB sectors, -40 C to +85 C operation and the standard eight signal functions. The Puya SSS suffix is explicitly SOP8 150-mil, not the source's 208-mil body, so the PCB land pattern must change and pin_compatible is false. If the existing 208-mil footprint must be retained, review P25Q80SH-SUH-IR as the package-compatible Puya order code. Security-register and unique-ID sizes also differ. Document review only; not bench, reliability or production qualified.
