Product details
Overview
W25Q80BLSNIG from Winbond is an 8M-bit (1MB) serial NOR flash memory IC designed for code storage and XIP execution in space-constrained embedded systems. It supports Standard, Dual, and Quad SPI interfaces, operates from 2.3V to 3.6V, delivers up to 200MHz equivalent data transfer rate in Quad I/O mode, and features 4KB uniform sectors, 256-byte page programming, and hardware/software write protection.
For engineers reviewing the W25Q80BLSNIG datasheet, W25Q80BLSNIG pinout, W25Q80BLSNIG application, or W25Q80BLSNIG equivalent, key selection considerations include its SOIC-8 150-mil (SN) package, Quad Enable (QE) bit dependency for 4-wire I/O, sector/block erase flexibility, JEDEC ID and SFDP register support, and compatibility with microcontroller boot ROM interfaces requiring fast read latency and low-power standby.
Technical Context
The W25Q80BLSNIG implements a SPI-compatible command set with three operational modes: Standard (4-pin: CLK, /CS, DI, DO), Dual I/O (6-pin: CLK, /CS, IO0, IO1, /WP, /HOLD), and Quad I/O (8-pin: CLK, /CS, IO0–IO3). Its internal architecture includes a 256-byte page buffer, status register-1/2 with non-volatile QE bit, and dedicated logic for suspend/resume during erase/program cycles.
It supports SPI modes 0 and 3, requires QE=1 in Status Register-2 to enable Quad I/O functionality (reassigning /WP and /HOLD as IO2/IO3), and provides hardware write protection via active-low /WP pin - disabled in Quad mode. The device integrates SFDP (Serial Flash Discoverable Parameters) for automatic configuration and a 64-bit unique serial number per unit.

Pinout & Package
W25Q80BLSNIG uses an 8-pin SOIC-150-mil package (package code SN), with gull-wing leads and standard JEDEC outline. Pin 1 is marked by a beveled corner or dot; pin numbering follows counter-clockwise orientation when viewing top side markings.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable signal; high-impedance outputs and standby power when high |
| DO (IO1) | Serial Data Output / Bidirectional I/O1 | Unidirectional output in Standard SPI; bidirectional in Dual/Quad modes; used for read data and status |
| /WP (IO2) | Write Protect Input / Bidirectional I/O2 | Hardware write lock for status register; repurposed as IO2 when Quad Enable (QE=1) is set |
| GND | Ground Reference | Primary return path for all digital and analog circuitry; must be low-impedance connection |
| DI (IO0) | Serial Data Input / Bidirectional I/O0 | Unidirectional input in Standard SPI; bidirectional in Dual/Quad modes; carries instructions, addresses, and write data |
| CLK | Serial Clock Input | Synchronous timing reference for all SPI operations; supports Mode 0 and Mode 3 polarity/phase |
| /HOLD (IO3) | Hold Input / Bidirectional I/O3 | Pauses ongoing SPI transaction while /CS remains low; repurposed as IO3 when QE=1 |
| VCC | Power Supply | Single 2.3–3.6 V supply; powers internal charge pumps, logic, and I/O buffers |
Key Features
| Feature | Design Value |
|---|---|

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 | Newer revision with enhanced reliability, improved deep power-down current (<0.5 µA), and extended endurance (≥200k cycles) | Same pinout and instruction set; preferred for new designs requiring longer lifecycle and lower standby power | Select W25Q80DVSNIG if long-term availability, lower power, or higher endurance is required; W25Q80BLSNIG remains valid for legacy qualification. |
| AT25SF041-SSHN-B | 4 M-bit density (half capacity), supports 104 MHz Quad SPI, includes independent sector protection bits not present in W25Q80BL | Not drop-in compatible due to smaller memory size; requires firmware address map adjustment | Choose AT25SF041-SSHN-B only when 4 M-bit capacity suffices and independent sector locks are critical; verify layout compatibility with SOIC-8 footprint. |
Compared with W25Q80BLSNIG, W25Q80DVSNIG offers measurable improvements in endurance and power-down current while maintaining full software and pin compatibility; AT25SF041-SSHN-B trades capacity and instruction parity for differentiated protection granularity, necessitating design-level validation.

FAQ
What is the package type and lead finish for W25Q80BLSNIG?
W25Q80BLSNIG uses an 8-pin SOIC-150-mil package (SN code) with matte tin lead finish, RoHS-compliant and halogen-free. The body dimensions are 5.3 mm × 4.1 mm × 1.75 mm, and it is rated for industrial temperature operation (-40°C to +85°C). This package is compatible with standard reflow profiles and automated pick-and-place assembly.
Does W25Q80BLSNIG support execute-in-place (XIP) operation?
Yes, W25Q80BLSNIG supports true XIP via its Continuous Read Mode, which reduces instruction overhead to just 8 clock cycles for address setup and enables efficient sequential access. When paired with a microcontroller's QSPI peripheral configured for Quad I/O, W25Q80BLSNIG allows direct code execution without copying to RAM - critical for memory-constrained boot stages.
How is Quad SPI functionality enabled on W25Q80BLSNIG?
Quad SPI on W25Q80BLSNIG is enabled by setting the Quad Enable (QE) bit in Status Register-2 using the Write Status Register instruction (01h). Once QE=1, pins /WP and /HOLD become IO2 and IO3 respectively. This change is non-volatile and persists across power cycles unless explicitly cleared, ensuring consistent interface behavior after initial configuration.
What write protection mechanisms does W25Q80BLSNIG provide?
W25Q80BLSNIG provides layered write protection: hardware via active-low /WP pin (disabled in Quad mode), software via Block Protect (BP2–BP0), Top/Bottom (TB), Sector/Block (SEC), and Complement (CMP) bits in Status Register-1, and non-volatile Status Register Protect (SRP0/SRP1). These can be combined to lock individual 4KB sectors or the entire array.
Is W25Q80BLSNIG compatible with JEDEC-standard identification commands?
Yes, W25Q80BLSNIG fully supports JEDEC-standard identification: Read JEDEC ID (9Fh) returns 0xEF4014, Read Manufacturer/Device ID (90h) returns 0xEF13, and Read SFDP Register (5Ah) provides standardized parameter tables for automatic driver configuration. These ensure interoperability with generic flash abstraction layers in RTOS and bootloader frameworks.
