Product details
Overview
W25Q80BWSSIG TR from Winbond is an 8 M-bit (1 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 80 MHz clock frequency, 4 KB uniform sector architecture, and 1.65–1.95 V single-supply operation - used for code storage, XIP execution, and firmware parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q80BWSSIG TR datasheet, W25Q80BWSSIG TR pinout, W25Q80BWSSIG TR application, or W25Q80BWSSIG TR equivalent, this page delivers verified pin functions, Quad SPI timing behavior, sector/block erase granularity, hardware write protection via /WP and /HOLD, and JEDEC-compliant identification - all confirmed for the SOIC-8 (150-mil, package code SN) variant marked "W25Q80BWSSIG TR".
Technical Context
The W25Q80BWSSIG TR implements a SPI-compatible command set with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI (IO0–IO3 enabled by QE bit in Status Register-2). It supports Fast Read Quad I/O (EBh) at up to 320 MHz equivalent bandwidth and Continuous Read Mode with ≤8-clock instruction overhead for true execute-in-place (XIP) capability.
Its memory array comprises 4,096 × 256-byte pages organized into 256 erasable 4 KB sectors and 16 erasable 64 KB blocks. Erase/program suspend/resume functionality enables concurrent background operations, while volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1, QE) provide granular software-controlled protection independent of /WP and /HOLD hardware pins.

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; device enters high-impedance output state when high; must transition high→low after power-up before first instruction |
| DO (IO1) | Data Output / Quad I/O Line 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes; used for read data and status |
| /WP (IO2) | Write Protect Input / Quad I/O Line 2 | Hardware lock for Status Register when QE = 0; repurposed as IO2 in Quad mode (QE = 1) |
| GND | Ground Reference | Primary signal return path; must be low-impedance connection to system ground plane |
| DI (IO0) | Data Input / Quad I/O Line 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes; carries instructions, addresses, and write data |
| CLK | Serial Clock Input | Edge-triggered timing reference; supports SPI Mode 0 and Mode 3; rising edge for input, falling edge for output |
| /HOLD (IO3) | Hold Input / Quad I/O Line 3 | Pauses ongoing SPI transfer when low (active-low); disabled in Quad mode (repurposed as IO3 when QE = 1) |
| VCC | Power Supply | 1.65–1.95 V supply; internal voltage regulators support stable core operation across full range |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with QE control | Enables 320 MHz equivalent bandwidth via IO0–IO3; requires non-volatile QE bit set in Status Register-2 |
| Continuous Read Mode | Reduces instruction overhead to ≤8 clocks per 24-bit address; enables deterministic XIP execution without prefetch stalls |
| 4 KB uniform sector erase | Allows fine-grained firmware partitioning - e.g., separate boot loader, app image, and NV config sectors - without over-erasure |
| Hardware + software write protection | /WP pin + BP/TB/SEC/CMP bits allow overlapping protection layers: top/bottom 4 KB, complement, or arbitrary sector ranges |
| 64-bit unique serial number | JEDEC-compliant per-device ID accessible via 4Bh instruction - supports secure device authentication and traceability |
| Erase/program suspend/resume | Permits interruption of long-duration erase or program operations to service time-critical interrupts, then resume from same address |

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 | Same density and pinout, but uses newer 1.7–2.0 V supply range and includes enhanced security registers with OTP locks | Required for new designs targeting extended voltage margin or mandatory secure boot key storage | Select W25Q80DVSSIG TR if migrating to Winbond's updated process node; not drop-in due to VCC min/max shift |
| AT25SF041-SSHD-B | 4 M-bit density (half capacity), 2.3–3.6 V supply, no Quad SPI support - only Standard and Dual SPI | Suitable for cost-sensitive, lower-code-footprint applications where 8 M-bit is unnecessary | Choose AT25SF041-SSHD-B only if design can accommodate reduced capacity and lacks Quad SPI dependency |
Compared with W25Q80BWSSIG TR, W25Q80DVSSIG TR offers tighter voltage tolerance and stronger security features but requires layout review for VCC compatibility, while AT25SF041-SSHD-B trades capacity and interface performance for broader supply range and lower unit cost - neither is pin- or functionally identical.

FAQ
What is the exact package type and marking for W25Q80BWSSIG TR?
W25Q80BWSSIG TR is packaged in an 8-pin SOIC-150-mil (package code SN) with gull-wing leads and JEDEC MS-012AC dimensions. The top-side marking reads "W25Q80BW" followed by date code and traceability symbols; "TR" denotes tape-and-reel packaging per AEC-Q200-compliant handling standards.
Does W25Q80BWSSIG TR support Quad SPI out of the box?
No - W25Q80BWSSIG TR requires the Quad Enable (QE) bit in Status Register-2 to be set via Write Status Register (01h) instruction before Quad SPI commands (e.g., EBh) become functional. Until QE = 1, /WP and /HOLD remain dedicated hardware protection pins, not IO2/IO3.
What is the minimum VCC voltage required for reliable operation of W25Q80BWSSIG TR?
W25Q80BWSSIG TR operates reliably from 1.65 V to 1.95 V. Below 1.65 V, the device enters reset state (VWI threshold), disabling all instructions. Power-up timing requires tPUW delay (~10 ms) after VCC exceeds 1.65 V before enabling Write Enable or Program commands.
Can W25Q80BWSSIG TR be used for Execute-in-Place (XIP) applications?
Yes - W25Q80BWSSIG TR supports true XIP via Continuous Read Mode with ≤8-clock instruction overhead and Fast Read Quad I/O (EBh), delivering up to 320 MHz equivalent bandwidth. This enables deterministic instruction fetch directly from flash without RAM shadowing in resource-constrained MCUs.
How does hardware write protection work on W25Q80BWSSIG TR?
W25Q80BWSSIG TR implements dual-layer hardware write protection: the /WP pin disables Status Register writes when pulled low, and the /HOLD pin pauses active transfers. Both are active-low and function only in Standard and Dual SPI modes - they are reassigned as IO2/IO3 in Quad mode when QE = 1.
