Product details
Overview
W25Q80JVSNIQ TR from Winbond is an 8 M-bit (1 MB) serial NOR flash memory with Dual/Quad SPI interface, organized as 4,096 × 256-byte pages, supporting 4 KB sector, 32 KB block, 64 KB block and chip erase, operating from 2.7 V to 3.6 V with <1 µA typical power-down current, and used for code shadowing, XIP execution, and firmware/data storage in space-constrained embedded systems.
For engineers reviewing the W25Q80JVSNIQ TR datasheet, W25Q80JVSNIQ TR pinout, W25Q80JVSNIQ TR application, or W25Q80JVSNIQ TR equivalent, key selection criteria include Quad SPI enable status, 133 MHz max clock support, 4 KB uniform sector architecture, hardware write protection granularity, and SOIC-8 150-mil package compatibility with legacy PCB footprints.
Technical Context
The W25Q80JVSNIQ TR implements a standard SPI bus (Mode 0/3) with optional Dual/Quad I/O modes enabled via the non-volatile Quad Enable (QE) bit in Status Register-2. It supports Fast Read Quad I/O (EBh) at up to 133 MHz clock, delivering up to 532 MHz effective throughput and 66 MB/s continuous read rate.
Its memory array features 256 erasable 4 KB sectors and 16 erasable 64 KB blocks, with flexible protection schemes including volatile/non-volatile Block Protect (BP2–BP0), Top/Bottom (TB), Sector Protect (SEC), Complement (CMP), and Individual Block Lock bits - all configurable via Write Status Register instructions and supported by three 256-byte Security Registers with OTP lock capability.

W25Q80JVSNIQ TR is supplied in an 8-pin SOIC-150-mil package (Package Code SN), with gull-wing leads, 1.27 mm pitch, and JEDEC MS-012AC compliant footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance outputs when deasserted; must track VCC during power-up/down |
| 2 DO (IO1) | Serial Data Output / I/O1 | Output in Standard/Dual SPI; bidirectional I/O in Dual/Quad mode; supports fast read dual output (3Bh) |
| 3 IO2 | Serial Data I/O2 | Bidirectional quad I/O pin; required for Quad SPI instructions (e.g., EBh); high-impedance when not active |
| 4 GND | Ground Reference | Primary signal return path; decoupling capacitor must be placed adjacent to this pin |
| 5 DI (IO0) | Serial Data Input / I/O0 | Input in Standard SPI; bidirectional I/O in Dual/Quad mode; carries all instructions and addresses |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| 7 IO3 | Serial Data I/O3 | Bidirectional quad I/O pin; required for full Quad SPI operation; unused in Standard/Dual modes |
| 8 VCC | Power Supply | 2.7–3.6 V supply; requires local 0.1 µF ceramic decoupling; internal voltage regulator enables stable core operation |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI Interface (QE bit) | Non-volatile Quad Enable bit allows persistent 4-line I/O mode without reconfiguration on every power cycle |
| 4 KB Uniform Sector Architecture | Enables fine-grained firmware partitioning - e.g., separate sectors for bootloader, app image, and NV parameters |
| Erase/Program Suspend & Resume | Allows background operations (e.g., logging) to pause flash writes, minimizing system latency impact |
| Three 256-byte Security Registers | OTP-lockable storage for cryptographic keys, calibration data, or device-specific secrets - isolated from main array |
| 64-bit Unique ID | Factory-programmed per-device serial number - enables secure device identity binding in cloud-connected systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| W25Q80DVSNIG | Same density, voltage, and SOIC-8 package; differs in revision (DV vs JV) and lacks factory-qualified QE bit - requires software initialization each power-on | Less suitable for XIP-critical systems where guaranteed Quad SPI persistence is required at reset | Select W25Q80JVSNIQ TR when Quad SPI must be active immediately post-reset without host intervention |
| AT25SF041-SSHD-B | 4 M-bit density (half capacity); supports 104 MHz Quad SPI; includes hardware reset (/RESET) pin not present on W25Q80JVSNIQ TR | Preferred where board-level reset coordination is needed and 4 MB suffices for firmware footprint | Choose W25Q80JVSNIQ TR when 8 M-bit capacity, 133 MHz performance, and JEDEC SFDP compliance are mandatory |
Compared with W25Q80DVSNIG, W25Q80JVSNIQ TR guarantees Quad SPI readiness at power-on via non-volatile QE; versus AT25SF041-SSHD-B, it doubles capacity and raises max clock by 29 MHz but omits dedicated /RESET - impacting system-level fault recovery design.

FAQ
What is the factory default Quad SPI enable state for W25Q80JVSNIQ TR?
The W25Q80JVSNIQ TR ships with the Quad Enable (QE) bit in Status Register-2 set to 1, enabling Quad SPI mode immediately after power-up without host initialization. This non-volatile setting persists across power cycles and distinguishes it from earlier revisions like the DV series, where QE defaults to 0 and requires explicit write to SR-2.
Does W25Q80JVSNIQ TR support Execute-in-Place (XIP) operation?
Yes, W25Q80JVSNIQ TR supports true XIP via Fast Read Quad I/O (EBh) and Set Burst with Wrap (77h) instructions, allowing microcontrollers to execute code directly from flash with minimal latency. Its 133 MHz Quad SPI clock and 66 MB/s sustained read rate meet real-time XIP timing budgets for ARM Cortex-M and RISC-V cores.
How many 4 KB sectors does W25Q80JVSNIQ TR contain, and what is their erase behavior?
W25Q80JVSNIQ TR contains exactly 256 uniform 4 KB sectors. Each sector can be erased independently using the Sector Erase (20h) instruction in ~100 ms (typ.), with no inter-sector coupling - enabling safe over-the-air firmware updates where only modified sectors are rewritten while preserving intact application partitions.
Is there a hardware reset pin on W25Q80JVSNIQ TR?
No, W25Q80JVSNIQ TR does not include a dedicated /RESET pin. Reset functionality is software-only via the Enable Reset (66h) + Reset Device (99h) instruction sequence. Hardware reset is only available on select Winbond packages (e.g., SOIC-16, TFBGA), not on the SOIC-8 variant used in W25Q80JVSNIQ TR.
What write protection mechanisms are implemented in W25Q80JVSNIQ TR?
W25Q80JVSNIQ TR implements layered write protection: (1) Status Register-based (BP2–BP0, TB, SEC, CMP, SRL), (2) Individual Block/Sector Lock bits (36h/39h), (3) Power-down instruction lockout, and (4) OTP-locked Security Registers. All are configurable via Write Status Register and lock instructions - no external hardware pins required.
