Product details
Overview
W25Q80DLUXIE from Winbond is an 8 M-bit (1 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with uniform 4 KB sectors and 64 KB blocks. It operates from 2.3 V to 3.6 V, supports up to 80 MHz Quad SPI clocking (320 MHz equivalent), delivers 40 MB/s continuous read throughput, and features hardware /WP and /HOLD pins plus non-volatile Quad Enable (QE) bit for XIP-capable embedded boot code storage.
For engineers reviewing the W25Q80DLUXIE datasheet, W25Q80DLUXIE pinout, W25Q80DLUXIE application, or W25Q80DLUXIE equivalent, this device is selected for low-voltage microcontroller boot memory, firmware update storage in space-constrained IoT nodes, and secure parameter retention requiring JEDEC ID, 64-bit unique serial number, and programmable sector-level write protection.
Technical Context
The W25Q80DLUXIE implements a SPI-compatible command set with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI (IO0–IO3), where /WP and /HOLD become IO2 and IO3 only when QE=1 in Status Register-2. Its architecture includes a 256-byte page buffer, 256 erasable 4 KB sectors, and 16 erasable 64 KB blocks, enabling flexible data partitioning.
It integrates volatile and non-volatile status register bits (including BP0–BP2, TB, SEC, CMP, SRP0/SRP1, SUS, LB1–LB3, and QE), supports Erase/Program Suspend & Resume, and provides 3×256-byte OTP-locked security registers. Power-down current is <1 µA (typ.), and data retention exceeds 20 years.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| W25Q80DVSSIG | Higher voltage range (2.7–3.6 V); 104 MHz Quad SPI clock; 50 MB/s read rate | Better suited for 3.3 V systems requiring maximum throughput; not rated for 2.3 V operation | Select W25Q80DVSSIG only if system VCC ≥2.7 V and bandwidth >40 MB/s is required. |
| MX25L8006EM1I-12G | Same density and 2.3–3.6 V range; supports 86 MHz Quad SPI; includes dual-plane erase and deep power-down mode | Offers faster erase suspend/resume and lower standby current (100 nA vs 1 µA), but lacks 64-bit unique ID | Prefer MX25L8006EM1I-12G for ultra-low-power battery applications where unique ID is not mandatory. |
Compared with W25Q80DLUXIE, W25Q80DVSSIG trades low-voltage operation for higher speed, while MX25L8006EM1I-12G improves power efficiency and erase flexibility at the cost of device identity assurance - making W25Q80DLUXIE optimal for 2.3 V–3.6 V designs needing secure, traceable firmware storage.

FAQ
What is the operating voltage range of the W25Q80DLUXIE?
The W25Q80DLUXIE operates from 2.3 V to 3.6 V, making it compatible with both 2.5 V and 3.3 V microcontroller I/O domains without level translation. This low-voltage capability supports energy-efficient designs in battery-powered applications, and its power-down current is specified at less than 1 µA (typical), ensuring minimal quiescent drain during sleep modes. The W25Q80DLUXIE maintains full functionality-including Quad SPI access and status register reads-across this entire range.
Does the W25Q80DLUXIE support Quad SPI mode out of the box?
No, the W25Q80DLUXIE requires the Quad Enable (QE) bit in Status Register-2 to be set to '1' before Quad SPI instructions (e.g., Fast Read Quad I/O EBh) will function. By default, QE=0 after power-up or reset, so Standard or Dual SPI must be used initially to issue Write Status Register (01h) with appropriate byte values. Once enabled, /WP and /HOLD pins become IO2 and IO3, and the device achieves up to 320 MB/s effective bandwidth. The W25Q80DLUXIE datasheet specifies this behavior in Section 7.1.10.
How many program/erase cycles does the W25Q80DLUXIE guarantee?
The W25Q80DLUXIE guarantees a minimum of 100,000 program/erase cycles per sector, validated across all 256 uniform 4 KB sectors. This endurance rating applies under standard operating conditions (25 °C, VCC = 2.3–3.6 V) and includes margin for temperature and voltage variation. Each sector may be cycled independently, allowing wear leveling in firmware - critical for applications like logging or configuration storage where certain regions are updated more frequently than others. The W25Q80DLUXIE retains data for over 20 years post-last-write.
What package type is used by the W25Q80DLUXIE?
The W25Q80DLUXIE uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 2 mm × 3 mm × 0.6 mm, with wettable flank leads and RoHS-compliant finish. This package code is 'UX' per Winbond's ordering nomenclature and is optimized for high-density PCB assembly, automated optical inspection (AOI), and thermal performance in compact enclosures. Unlike SOIC or WSON variants, the USON UX package offers superior board-level reliability in vibration-prone environments due to its solder-joint geometry.
Can the W25Q80DLUXIE be used for secure boot applications?
Yes, the W25Q80DLUXIE supports secure boot through multiple hardware-enforced mechanisms: a 64-bit unique serial number for device identity, JEDEC-standard Manufacturer/Device ID (90h/9Fh), SFDP register for verified timing parameters, and three 256-byte security registers with OTP (One-Time Programmable) lock bits (LB1–LB3). These features allow cryptographic key binding, firmware signature verification, and immutable configuration storage - all accessible via standard SPI commands. The W25Q80DLUXIE's hardware /WP pin and status register protection further prevent unauthorized modification during boot sequence execution.
