Product details
Overview
W25Q80EWUXIE TR from Winbond is an 8 M-bit (1 MB) serial NOR flash memory IC supporting Dual/Quad SPI and QPI interfaces, operating from 1.65V to 1.95V, with 104 MHz max clock, 4 KB uniform sector erase, and 1 µA power-down current. It enables XIP (execute-in-place) code execution, firmware storage, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q80EWUXIE TR datasheet, W25Q80EWUXIE TR pinout, W25Q80EWUXIE TR application, or W25Q80EWUXIE TR equivalent, key selection considerations include Quad Enable (QE) bit configuration, USON 2×3 mm package compatibility, 1.8 V supply tolerance, and Fast Read Quad I/O (EBh) timing compliance.
Technical Context
The W25Q80EWUXIE TR implements a SPI-compatible command set with mode-selectable operation: Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), and QPI (4-line instruction + data). Its architecture includes a 256-byte page buffer, 256 × 4 KB erasable sectors, and dual status registers with non-volatile QE bit enabling Quad I/O mode.
It supports JEDEC JESD216 SFDP v1.5 for discoverable parameters, 64-bit unique serial number, three 256-byte security registers with OTP locks, and Erase/Program Suspend & Resume-enabling concurrent background operations without host intervention.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 M-bit (1,048,576 bytes), organized as 4,096 × 256-byte pages |
| Supply Voltage | 1.65 V to 1.95 V - ensures compatibility with low-voltage SoCs and battery-powered designs |
| Max Clock Frequency | 104 MHz for SPI/Dual/Quad I/O - enables 416 MB/s effective throughput in Quad I/O mode |
| Erase Granularity | Uniform 4 KB sectors (256 total), plus 32 KB and 64 KB blocks - supports fine-grained firmware partitioning |
| Endurance & Retention | 100,000 program-erase cycles per sector; >20 years data retention at 25°C |
| Interface Modes | Standard SPI, Dual SPI, Quad SPI, and QPI - selectable via instruction; QE bit in Status Register-2 controls Quad I/O activation |
| Power Consumption | 1 mA active current; <1 µA deep power-down - critical for always-on IoT sensor nodes |
Pinout & Package
W25Q80EWUXIE TR is packaged in an 8-pad USON 2×3 mm (package code UXIE), with wettable flank leads for automated optical inspection. Pin functions are identical across SOIC, VSOP, WSON, and USON variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO/IOx when deasserted; required low-to-high transition before new instruction acceptance |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad/QPI modes; falls on CLK edge per SPI mode |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware write lock for status register when QE=0; becomes IO2 in Quad/QPI modes (QE=1) |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable timing and noise immunity |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad/QPI; rises on CLK edge per SPI mode |
| 6 CLK | Serial Clock Input | Master-generated timing signal; supports Mode 0 and Mode 3; determines data sampling edges for all instructions |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing read/write when asserted low (QE=0); becomes IO3 in Quad/QPI modes (QE=1) |
| 8 VCC | Power Supply | 1.65–1.95 V core supply; decoupling capacitor required within 5 mm for stable 104 MHz operation |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead by 75% vs. standard SPI - only 2 clocks needed to send 8-bit opcodes instead of 8 |
| Erase/Program Suspend & Resume | Allows host to pause long erase/program operations and service interrupts, then resume from exact point - no data loss or timeout risk |
| 64-bit Unique Serial Number | Factory-programmed per-device ID - enables secure device authentication, firmware binding, and field failure traceability |
| Security Registers (3 × 256 B) | OTP-lockable zones for keys, certificates, or calibration data - prevents unauthorized readback or overwrite after lock |
| SFDP v1.5 Compliance | Self-describing parameter table accessible via 5Ah instruction - eliminates hard-coded timing assumptions in bootloader/firmware |
| Hardware Write Protection | /WP pin + BP/TB/SEC bits enable selective 4 KB sector locking - protects boot code while allowing runtime parameter updates |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L8006EM1I-12G | 3 V supply (2.7–3.6 V); same 8 M-bit density, SOIC-8 only; no QPI mode; 86 MHz max clock | Requires level-shifting for 1.8 V systems; lacks suspend/resume and SFDP; limited to Standard/Dual SPI | Select only if legacy 3 V design exists and Quad I/O/XIP is unnecessary. |
| AT25SF041-SSHD-B | 1.7–2.0 V supply; 4 M-bit density (half capacity); supports XIP but no QPI; 104 MHz clock; 2.5 mm × 3 mm USON | Insufficient capacity for full firmware images; lacks security registers and unique ID; no Erase Suspend | Use only for cost-sensitive, low-complexity applications where 4 MB suffices and security features are optional. |
Compared with MX25L8006EM1I-12G and AT25SF041-SSHD-B, the W25Q80EWUXIE TR uniquely delivers 1.8 V operation with QPI, 64-bit UID, suspend/resume, and SFDP in the same USON 2×3 mm footprint - making it the only option for secure, high-speed, low-power XIP in modern ultra-compact designs.

FAQ
What is the package type and lead finish of W25Q80EWUXIE TR?
W25Q80EWUXIE TR uses an 8-pad USON package measuring 2 mm × 3 mm with wettable flank leads and matte tin (Sn) surface finish. This package supports automated optical inspection (AOI) and is optimized for high-density PCB layouts in portable and space-constrained applications. The "UXIE" suffix explicitly denotes the USON 2×3 mm variant with industrial temperature range (-40°C to +85°C).
Does W25Q80EWUXIE TR support execute-in-place (XIP) operation?
Yes, W25Q80EWUXIE TR supports XIP via Dual SPI and Quad SPI interfaces using Fast Read Dual I/O (BBh) and Fast Read Quad I/O (EBh) instructions. With up to 416 MB/s effective throughput in Quad I/O mode and low-latency random access, it enables direct code execution from flash on compatible microcontrollers - eliminating the need for RAM shadowing in many embedded applications.
How is Quad SPI mode enabled on W25Q80EWUXIE TR?
Quad SPI mode on W25Q80EWUXIE TR is enabled by setting the Quad Enable (QE) bit in Status Register-2 (SR2) using the Write Status Register-2 (31h) instruction. Once QE = 1 (non-volatile), pins /WP and /HOLD become IO2 and IO3 respectively. The device must be powered-cycled or reset after writing QE to activate Quad I/O functionality - standard SPI commands remain available until QE is set.
What security features does W25Q80EWUXIE TR provide beyond basic write protection?
W25Q80EWUXIE TR provides layered security: hardware /WP pin protection, software-configurable sector/block locking (BP/TB/SEC bits), volatile/non-volatile status register protection (SRP/SRL), 64-bit unique serial number, three 256-byte OTP-lockable security registers, and JEDEC SFDP for authenticated parameter discovery. These features collectively support secure boot, firmware attestation, and tamper-resistant data storage in regulated environments.
Can W25Q80EWUXIE TR operate reliably at 1.65 V supply voltage?
Yes, W25Q80EWUXIE TR is fully specified for operation across 1.65 V to 1.95 V. All AC/DC electrical characteristics - including 104 MHz maximum clock, 1 µA power-down current, and valid setup/hold timing - are guaranteed at the 1.65 V minimum. This makes W25Q80EWUXIE TR suitable for single-cell Li-ion or coin-cell powered devices where voltage droop occurs during peak current draw.
