Product details
Overview
W25X80AVSSIG from Winbond is an 8M-bit (1MB) serial Flash memory IC with uniform 4KB sectors and dual-output SPI interface, operating at 2.7–3.6V supply, supporting up to 100MHz clock and 200Mbps data transfer via Fast Read Dual Output (3Bh), used for code shadowing, firmware storage, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25X80AVSSIG datasheet, W25X80AVSSIG pinout, W25X80AVSSIG application, or W25X80AVSSIG equivalent, key selection considerations include sector-erase granularity (4KB), hardware/software write protection (/WP pin + BP/TB bits), SOIC-208-mil package compatibility, and JEDEC ID (EFh/3014h) verification.
Technical Context
The W25X80AVSSIG implements a standard SPI bus (Modes 0 and 3) with dedicated DO and bidirectional DIO pins, enabling dual-output read mode where DIO functions as a second data output during Fast Read Dual Output (3Bh) instruction. Its internal architecture supports page-program (256B max, <2ms), sector-erase (4KB), block-erase (64KB), and chip-erase operations.
Write protection is enforced through both hardware (/WP pin active-low control of Status Register writes when SRP=1) and software (BP2–BP0 and TB bits in Status Register defining protected address ranges), with factory-default unprotected state and >100,000 erase/write cycles. The device enters power-down mode (1µA typical) via B9h instruction and resumes via ABh.

Pinout & Package
W25X80AVSSIG is packaged in an 8-pin SOIC 208-mil (Package Code SS), with gull-wing leads, 1.27 mm pitch, and body dimensions of 5.33 mm × 5.33 mm. Pin 1 marked by notch or dot; pin 4 = GND, pin 8 = VCC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; must transition high→low before instruction acceptance; controls DO high-impedance state |
| DO | Serial Data Output | Unidirectional output; data shifted out on CLK falling edge; used in standard and dual-output reads |
| /WP | Write Protect Input | Hardware lock for Status Register writes when SRP=1; active-low; enables top/bottom array protection |
| GND | Ground Reference | Signal and power return path; decoupling capacitor required near pin 4 for noise immunity |
| DIO | Serial Data I/O | Bidirectional SPI data line; latched on CLK rising edge; serves as second output during 3Bh instruction |
| CLK | Serial Clock Input | Master-generated timing signal; supports Modes 0 and 3; defines setup/hold timing for DIO/DO |
| /HOLD | Hold Input | Pauses ongoing SPI operation while /CS remains low; isolates DIO/CLK; useful in multi-device bus sharing |
| VCC | Power Supply | 2.7–3.6 V core supply; requires local 0.1 µF ceramic decoupling between pins 4 and 8 |
Key Features
| Feature | Design Value |
|---|---|
| Dual Output SPI Interface | Enables 200 Mbps read throughput using Fast Read Dual Output (3Bh), doubling standard SPI bandwidth for fast code loading |

| Low-Power Power-down Mode | B9h instruction reduces current to 1 µA typical, ideal for battery-backed systems requiring long-term non-volatile retention |
| Industrial Temperature Range | Guaranteed operation from −40°C to +85°C, validated across voltage and timing margins for automotive and industrial control applications |
Applications
| Firmware Storage | Bootloader Execution |

Use Scenario: Hosting secure bootloader code that validates application integrity before execution in medical diagnostic equipment. IC Role / Device Role / Timing Role: Trusted code source verified at power-on reset; uses hardware /WP and BP bits to lock bootloader region against runtime corruption. Use Value: Factory-configurable top/bottom protection (TB bit) ensures bootloader resides in immutable memory, meeting IEC 62304 safety requirements. |
| Parameter Configuration | Audio Data Caching |
Use Scenario: Retaining calibration coefficients and user preferences across power cycles in industrial motor drives. IC Role / Device Role / Timing Role: Parameter store accessed infrequently but requiring high endurance; erased/written per 4KB sector to minimize wear. Use Value: >100,000 erase/write cycles and 20-year retention guarantee stable operation over product lifetime without refresh logic. |
Use Scenario: Buffering compressed audio samples for real-time playback in portable voice assistants. IC Role / Device Role / Timing Role: High-speed read buffer; leverages Fast Read Dual Output (3Bh) to sustain 200 Mbps streaming to DAC controller. Use Value: 100 MHz clock support and dual-output capability eliminate need for larger parallel Flash, reducing BOM cost and layout complexity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial Flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| W25Q80DVSSIG | Successor with Quad SPI (QPI) support, 3-byte addressing, and enhanced security registers; same pinout and voltage range | Required for designs needing faster random-access reads or QPI protocol compatibility (e.g., XIP-capable MCUs) | Select W25Q80DVSSIG if migrating to newer Winbond generation with quad-mode capability; not drop-in for legacy dual-SPI-only firmware |
| AT25DF081A-SSH-T | 8 M-bit SPI Flash from Microchip; supports standard SPI only (no dual-output); identical SOIC-208 package and 2.7–3.6 V operation | Suitable where dual-output bandwidth is unnecessary and cross-manufacturer second sourcing is prioritized | Choose AT25DF081A-SSH-T for pin-compatible replacement with simplified driver stack; verify timing margins due to different tPP/tSE values |
Compared with W25X80AVSSIG, W25Q80DVSSIG adds quad-SPI and security features but requires firmware updates, while AT25DF081A-SSH-T offers direct pin compatibility with reduced feature set-making it suitable for cost-sensitive, bandwidth-tolerant replacements.

FAQ
What is the memory organization of the W25X80AVSSIG?
The W25X80AVSSIG contains 8 M-bit (1,048,576 bytes) of NOR Flash memory, organized into 4096 programmable pages of 256 bytes each, grouped into 256 uniform 4KB sectors and 16 erasable 64KB blocks. This structure enables flexible updates-such as modifying individual configuration sectors without affecting firmware code stored elsewhere-and is explicitly defined in the "General Description" section of the August 2009 datasheet.
Does the W25X80AVSSIG support dual-output SPI reads, and how is it enabled?
Yes, the W25X80AVSSIG supports dual-output SPI reads using the Fast Read Dual Output instruction (0x3B). When this command is issued, the DIO pin functions as a second data output alongside DO, delivering two bits per clock cycle and achieving up to 200 Mbps throughput at 100 MHz clock. This mode is distinct from standard SPI and requires explicit instruction initiation-not automatic activation-and is documented in Section 9.1.2 of the datasheet.
How does hardware write protection work on the W25X80AVSSIG?
Hardware write protection on the W25X80AVSSIG is implemented via the /WP pin in conjunction with the Status Register Protect (SRP) bit. When SRP = 1, asserting /WP low disables all Status Register writes-including Block Protect (BP2–BP0) and Top/Bottom (TB) bit modifications-preventing unauthorized memory lockdown. This mechanism is independent of software write-enable state and is detailed in Sections 7.4 and 9.2.1 of the datasheet.
What package type does the W25X80AVSSIG use, and what are its mechanical identifiers?
The W25X80AVSSIG uses an 8-pin SOIC 208-mil package (Package Code SS), with body dimensions of 5.33 mm × 5.33 mm, 1.27 mm lead pitch, and gull-wing leads. It is distinct from the 150-mil SOIC (SN) and WSON (ZP) variants-only W25X40A and W25X80A are offered in this 208-mil variant per Section 7.1 of the datasheet, and the "VSSIG" suffix confirms this packaging.
Can the W25X80AVSSIG be used in industrial temperature applications?
Yes, the W25X80AVSSIG is rated for operation from −40°C to +85°C, as specified in Section 11.2 ("Operating Ranges") of the datasheet. This industrial temperature grade is guaranteed across all electrical parameters-including timing, endurance, and data retention-making it suitable for deployment in motor drives, industrial HMIs, and outdoor sensor nodes without derating.
