Product details
Overview
W25Q80BLSNIG TR from Winbond is an 8M-bit (1MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 50MHz clock rate, 4KB uniform sector erase architecture, and XIP-capable continuous read mode - used for code storage, firmware boot, and parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q80BLSNIG TR datasheet, W25Q80BLSNIG TR pinout, W25Q80BLSNIG TR application, or W25Q80BLSNIG TR equivalent, key selection criteria include quad I/O enable (QE bit), hardware write protect (/WP) and hold (/HOLD) functionality, 2.3–3.6V single-supply operation, -40°C to +85°C industrial temperature range, and SOIC-8 150-mil (SN) package compatibility.
Technical Context
The W25Q80BLSNIG TR implements a SPI command set compliant with JEDEC JESD216 SFDP v1.5, enabling auto-configuration of read modes via the Serial Flash Discoverable Parameters register. It supports four SPI modes (0 and 3 primary), with Quad SPI requiring non-volatile QE bit setting in Status Register-2 to repurpose /WP and /HOLD as IO2/IO3.
Its internal architecture includes a 256-byte page buffer, 4KB sector/32KB & 64KB block erase granularity, and dual status registers (SR1/SR2) managing protection (BP2–BP0, TB, SEC, CMP), suspend/resume, and security lock bits (LB1–LB3). Erase/program cycles exceed 100,000 with >20-year data retention.
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 | 2.3 V to 3.6 V - enables direct interface with 3.3V MCU I/O without level shifting |
| Max Clock Frequency | 50 MHz for standard/Dual/Quad SPI - delivers up to 200 MB/s effective throughput in Quad I/O mode |
| Erase Granularity | Uniform 4KB sectors (256 total), plus 32KB and 64KB blocks - supports fine-grained firmware update partitioning |
| Write Endurance | 100,000 program/erase cycles per sector - suitable for field-upgradable firmware with frequent minor updates |
| Data Retention | 20 years at +85°C - validated for industrial lifecycle requirements without refresh |
| Operating Temp | -40°C to +85°C - qualified for automotive body control, industrial HMI, and outdoor IoT edge nodes |
| Power Consumption | 4 mA active current; <1 µA power-down - reduces standby power in battery-backed systems |
Pinout & Package
W25Q80BLSNIG TR uses an 8-pin SOIC-150-mil (package code SN) surface-mount package with gull-wing leads, 1.27 mm pitch, and RoHS-compliant matte tin finish. Pin 1 marked by notch or dot; body dimensions 5.3 mm × 4.1 mm × 1.75 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable: drives DO/IOx high-Z when high; required low-to-high transition before first instruction post-power-up |
| DO (IO1) | Serial Data Output / Bidirectional I/O1 | Standard SPI output only; becomes bidirectional I/O1 in Dual/Quad mode - shares pin function across SPI variants |
| /WP (IO2) | Hardware Write Protect / Bidirectional I/O2 | Active-low hardware lock for status register; repurposed as IO2 when QE=1 - disables /WP function in Quad mode |
| GND | Ground Reference | Primary return path for VCC and all I/O signals; requires low-inductance connection to minimize noise during fast reads |
| DI (IO0) | Serial Data Input / Bidirectional I/O0 | Standard SPI input only; becomes bidirectional I/O0 in Dual/Quad mode - essential for instruction/address loading |
| CLK | Serial Clock Input | Edge-triggered timing source: rising edge for input sampling, falling edge for output valid - supports SPI modes 0 and 3 |
| /HOLD (IO3) | Hold Input / Bidirectional I/O3 | Pauses ongoing SPI transaction when low (active); repurposed as IO3 when QE=1 - unavailable during Quad operation |
| VCC | Power Supply | Single 2.3–3.6V supply powering core logic, charge pumps, and I/O buffers - decoupling capacitor mandatory |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with QE bit | Enables 4-line data transfer (IO0–IO3) after non-volatile QE=1 setting - doubles bandwidth vs Dual SPI without layout change |
| Continuous Read Mode | As few as 8 clocks overhead to address memory - enables true execute-in-place (XIP) from flash for Cortex-M boot code |
| 4KB Uniform Sector Erase | Allows independent erasure of smallest 4KB unit - critical for storing calibrated sensor offsets or runtime configuration without disturbing firmware |
| 64-bit Unique ID | Factory-programmed serial number readable via 4Bh instruction - supports device authentication and secure firmware binding |
| Security Registers | Three 256-byte OTP-lockable regions (SR1–SR3) - stores cryptographic keys or calibration data immune to field reprogramming |
| SFDP Register | JESD216-compliant parameter table at 00FF00h - enables automatic driver initialization without hard-coded timing constants |
Applications

IC Role / Device Role / Timing Role: Parameter archive with individual 4KB sector write protection - isolates calibration data from firmware updates using BP0–BP2 bits. Use Value: Guarantees lifetime accuracy by preventing accidental overwrite during field firmware upgrades, validated over -40°C to +85°C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| W25Q80DVSNIG | Same density, voltage, and pinout; supports DTR (Double Transfer Rate) mode and enhanced SFDP v1.6; higher max clock (104MHz in DTR Quad) | Enables faster boot in high-performance applications (e.g., RISC-V SoCs); requires updated driver for DTR command set | Select W25Q80DVSNIG if system demands >50MHz read throughput and supports DTR protocol stack. |
| AT25SF041-SSHD-B | 4M-bit density (half capacity); supports 1.65–3.6V supply; identical SOIC-8 150-mil package; lacks Quad I/O and SFDP | Suitable for cost-sensitive designs where 4MB suffices and Quad SPI not required; no QE bit or continuous read mode | Choose AT25SF041-SSHD-B only for legacy 4MB-restricted designs lacking XIP or high-speed read needs. |
Compared with W25Q80BLSNIG TR, W25Q80DVSNIG offers higher bandwidth and modern SFDP but requires firmware adaptation, while AT25SF041-SSHD-B trades capacity and features for lower unit cost - neither is pin-compatible drop-in replacement due to differing QE implementation and instruction set extensions.

FAQ
What is the package type and lead count of the W25Q80BLSNIG TR?
The W25Q80BLSNIG TR uses an 8-pin SOIC-150-mil (SN) package with gull-wing leads, 1.27 mm pitch, and RoHS-compliant matte tin plating. Its body measures 5.3 mm × 4.1 mm × 1.75 mm, and pin 1 is identified by a notch or dot. This package is compatible with standard reflow profiles and automated pick-and-place assembly.
Does the W25Q80BLSNIG TR support Quad SPI operation out of the box?
No - the W25Q80BLSNIG TR requires the non-volatile Quad Enable (QE) bit in Status Register-2 to be set to '1' before Quad SPI instructions (e.g., EBh, 6Bh) will function. Until QE is programmed, /WP and /HOLD remain dedicated hardware control pins. The QE bit is set via Write Status Register (01h) after issuing Write Enable (06h).
How does hardware write protection work on the W25Q80BLSNIG TR?
Hardware write protection on the W25Q80BLSNIG TR is enabled by pulling the /WP pin low, which locks the Status Register from modification when SRP0/SRP1 bits are configured. This prevents changes to block protection bits (BP2–BP0) and QE. Note that /WP is disabled during Quad SPI operation (when QE=1), as the pin becomes IO2.
Can the W25Q80BLSNIG TR be used for execute-in-place (XIP) applications?
Yes - the W25Q80BLSNIG TR supports true XIP via its Continuous Read Mode, which minimizes instruction overhead to as few as 8 clocks per 24-bit address. Combined with Fast Read Quad I/O (EBh) and 50MHz clock, it delivers sufficient bandwidth for Cortex-M0+/M3/M4 boot code execution without RAM loading.
What is the purpose of the 64-bit Unique ID in the W25Q80BLSNIG TR?
The 64-bit Unique ID in the W25Q80BLSNIG TR is factory-programmed and read-only, accessible via instruction 4Bh. It provides cryptographically verifiable device identity for secure boot chain binding, firmware anti-cloning, and production traceability - critical for medical, industrial, and automotive applications requiring device-level authentication.
