Product details
Overview
W25Q80DLUXIE TR from Winbond is an 8 M-bit (1 MB) serial NOR flash memory IC supporting Dual and Quad SPI interfaces, operating from 2.3V to 3.6V, with 4 KB uniform sectors, 100,000+ program/erase cycles, and 20-year data retention - deployed in microcontroller boot code storage, firmware update partitions, and embedded configuration parameter storage.
For engineers reviewing the W25Q80DLUXIE TR datasheet, W25Q80DLUXIE TR pinout, W25Q80DLUXIE TR application, or W25Q80DLUXIE TR equivalent, key selection criteria include voltage range compatibility (2.3–3.6 V), USON 2×3-mm package footprint, Quad SPI enable (QE bit) configuration, sector-level write protection granularity, and JEDEC ID / SFDP register support for automated initialization.
Technical Context
The W25Q80DLUXIE TR implements a standard SPI bus (Mode 0/3) with optional Dual SPI (IO0/IO1) and Quad SPI (IO0–IO3) operation enabled via non-volatile QE bit in Status Register-2. It supports Fast Read Quad I/O (EBh) at up to 80 MHz clock frequency, delivering 320 MHz equivalent throughput and 40 MB/s continuous read rate.
Its architecture includes 4,096 × 256-byte pages, 256 erasable 4 KB sectors, 16 × 64 KB blocks, and dedicated security registers (3 × 256 bytes) with OTP lock capability. Write protection combines hardware (/WP pin) and software control (BP0–BP2, TB, SEC, CMP bits), with SRP0/SRP1 enabling status register lockdown.

Pinout & Package
W25Q80DLUXIE TR uses an 8-pad USON package (2 mm × 3 mm × 0.6 mm, package code UX), optimized for space-constrained PCB layouts and reflow-compatible assembly. Pin assignments follow standard SPI-compatible layout with bidirectional I/O capability under Dual/Quad modes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable signal; must transition high→low after power-up before first instruction; controls DO high-impedance state |
| DI (IO0) | Data Input / Quad I/O 0 | Standard SPI input (rising CLK edge); becomes bidirectional IO0 in Dual/Quad mode; required for all instructions |
| DO (IO1) | Data Output / Quad I/O 1 | Standard SPI output (falling CLK edge); becomes bidirectional IO1 in Dual/Quad mode; carries status/data during reads |
| /WP (IO2) | Write Protect Input / Quad I/O 2 | Hardware write protect for status register when QE=0; repurposed as IO2 in Quad mode (QE=1) |
| /HOLD (IO3) | Hold Input / Quad I/O 3 | Pauses active SPI transaction when low (CS=low); repurposed as IO3 in Quad mode (QE=1); not available during Quad operation |
| CLK | Serial Clock Input | Master-generated timing signal; supports Mode 0 (CLK idle low) and Mode 3 (CLK idle high); max 80 MHz in Quad mode |
| VCC | Power Supply | Single 2.3–3.6 V supply; powers internal charge pumps for erase/program; <1 µA typical standby current |
| GND | Ground Reference | Return path for VCC and all I/O signals; requires low-impedance connection to minimize noise on SPI lines |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Enable (QE bit) | Non-volatile Status Register-2 bit that unlocks IO2 (/WP) and IO3 (/HOLD) for 4-line data transfer - essential for XIP and high-speed boot loading |
| Erase/Program Suspend | 75h/7Ah instructions allow pausing long erase/program operations to service time-critical interrupts - preserves buffer state without data loss |
| Security Registers | Three 256-byte OTP-lockable registers (42h/44h/48h) for storing keys, calibration data, or device-specific secrets - isolated from main array |
| JEDEC ID & Unique Serial Number | 9Fh command returns manufacturer/device ID; 4Bh reads 64-bit unique ID - enables secure device authentication and BOM traceability |
| Power-down Mode | B9h instruction reduces current to <1 µA; ABh wakes device - extends battery life in always-on sensor nodes and wearables |

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 TR | Higher voltage range (2.7–3.6 V); 104 MHz Quad SPI clock; 50 MB/s read rate; SOIC-8 package | Better performance for high-speed boot and XIP; incompatible with sub-2.7 V systems | Select when system VCC ≥2.7 V and higher throughput justifies larger SOIC footprint |
| MX25L8006EM1I-12G | Same density and USON-8 package; 104 MHz Quad SPI; supports DTR mode; different SFDP layout | Requires driver adaptation for SFDP parsing; slightly higher ICC active current | Choose for cross-manufacturer supply diversification where pinout and voltage match but firmware supports alternate SFDP structure |
Compared with W25Q80DLUXIE TR, W25Q80DVSSIG TR delivers higher bandwidth but lacks 2.3 V operation, while MX25L8006EM1I-12G offers identical packaging and voltage but demands SFDP-aware driver updates - making W25Q80DLUXIE TR optimal for ultra-low-voltage, space-constrained designs requiring drop-in compatibility with Winbond's ecosystem.

FAQ
What is the minimum supply voltage supported by the W25Q80DLUXIE TR?
The W25Q80DLUXIE TR operates from 2.3 V to 3.6 V, making it compatible with single-cell Li-ion (2.5–4.2 V) and low-power 2.5 V logic systems. This 2.3 V minimum enables reliable operation during battery voltage sag, unlike the 2.7 V minimum of the W25Q80DV variant. The W25Q80DLUXIE TR maintains full functionality-including Quad SPI reads and program/erase-across this entire range.
Does the W25Q80DLUXIE TR support Quad SPI operation out of the box?
No, Quad SPI operation requires setting the non-volatile Quad Enable (QE) bit in Status Register-2 using the Write Status Register (01h) instruction. Until QE=1, /WP and /HOLD remain dedicated hardware control pins. The W25Q80DLUXIE TR defaults to Standard SPI mode at power-up; enabling Quad mode is a one-time configuration step during system initialization.
How is write protection implemented on the W25Q80DLUXIE TR?
The W25Q80DLUXIE TR provides dual-layer write protection: hardware-based via the active-low /WP pin (protects status register only), and software-configurable via Block Protect (BP0–BP2), Top/Bottom (TB), Sector/Block (SEC), and Complement (CMP) bits in the status register. These settings allow locking individual 4 KB sectors or contiguous regions without altering firmware logic - a key advantage over basic EEPROM emulation.
What package type does the W25Q80DLUXIE TR use, and what are its dimensions?
The W25Q80DLUXIE TR uses an 8-pad USON (Ultra Thin Small Outline No-lead) package measuring 2.0 mm × 3.0 mm × 0.6 mm (package code UX). Its land pattern matches JEDEC MO-252, with exposed pad thermal design for improved heat dissipation in dense layouts. This compact footprint is ideal for wearables, hearing aids, and miniaturized industrial sensors where board space is constrained.
Can the W25Q80DLUXIE TR be used for Execute-in-Place (XIP) applications?
Yes, the W25Q80DLUXIE TR supports XIP via Fast Read Quad I/O (EBh) instructions, achieving up to 40 MB/s continuous read throughput at 80 MHz clock. When paired with an MCU supporting Quad SPI memory-mapped mode (e.g., STM32H7, NXP i.MX RT), the W25Q80DLUXIE TR enables direct code execution without copying to RAM - reducing boot time and SRAM usage in real-time embedded systems.
