Product details
Overview
W25Q80BVSNIG from Winbond is an 8 M-bit (1 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces. It features 4,096 × 256-byte pages, 4 KB uniform sector erase, 104 MHz max clock rate, and operates from 2.5V to 3.6V. It is used for code storage, XIP execution, and firmware parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q80BVSNIG datasheet, W25Q80BVSNIG pinout, W25Q80BVSNIG application, or W25Q80BVSNIG equivalent, key selection considerations include Quad SPI enable (QE bit), /WP and /HOLD dual-role behavior in Quad mode, 4 KB sector granularity, JEDEC ID compatibility, and continuous read mode timing for XIP efficiency.
Technical Context
The W25Q80BVSNIG implements a SPI command set with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where /WP and /HOLD become IO2 and IO3 only when the non-volatile Quad Enable (QE) bit in Status Register-2 is set. Its architecture includes a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers with OTP lock capability.
It supports erase suspend/resume, hardware write protection via active-low /WP (disabled in Quad mode), and hold functionality active only in Standard/Dual SPI. Power-down current is <1 µA, and data retention exceeds 20 years with >100,000 program/erase cycles.
Key Specifications

Pinout & Package
W25Q80BVSNIG uses an 8-pin SOIC 208-mil package (package code SS), with gull-wing leads and standard JEDEC outline. Pin 1 is marked with a notch or dot; pin numbering follows counter-clockwise convention from top-left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: device enters high-impedance output state when high; required low-to-high transition resets instruction pipeline |
| 2 DO (IO1) | Data Output / I/O1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad SPI; outputs status/data on CLK falling edge |
| 3 /WP (IO2) | Write Protect Input / I/O2 | Hardware write protect for status register when QE=0; becomes IO2 in Quad mode (QE=1) |
| 4 GND | Ground Reference | Primary signal return path; must be low-impedance and decoupled near VCC pin |
| 5 DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad SPI; accepts instructions/addresses/data on CLK rising edge |
| 6 CLK | Serial Clock Input | Synchronous timing reference; supports SPI modes 0 and 3; max 104 MHz frequency |
| 7 /HOLD (IO3) | Hold Input / I/O3 | Pauses ongoing SPI transaction when low (Standard/Dual only); becomes IO3 in Quad mode (QE=1) |
| 8 VCC | Power Supply | 2.5–3.6 V supply; requires local 0.1 µF ceramic decoupling capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with QE bit | Enables 4-line bidirectional I/O (IO0–IO3) for 4× bandwidth vs Standard SPI; requires non-volatile QE=1 setting |
| Continuous Read Mode | Reduces instruction overhead to ≤8 clocks per 24-bit address; enables true execute-in-place (XIP) from flash without RAM copy |
| Uniform 4 KB Sector Erase | Allows fine-grained firmware update and parameter storage without disturbing adjacent code or configuration data |
| 64-bit Unique Serial Number | Provides device-level traceability and secure boot binding; readable via 4Bh instruction |
| Security Registers | Three 256-byte OTP-lockable registers for keys, certificates, or calibration data; protected by LB1–LB3 bits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L8006EM1I-12G | 8 M-bit, 104 MHz max clock, SOIC-8 208-mil, but lacks Quad SPI I/O (IO2/IO3) and SFDP register | Supports only Standard/Dual SPI; no continuous read wrap or XIP optimization | Choose when Quad SPI and XIP are unnecessary and legacy SPI controller compatibility is prioritized |
| S25FL008KAGMFI011 | 8 M-bit, 85 MHz max clock, SOIC-8 208-mil, includes Quad SPI and SFDP, but requires different QE bit location (SR1[1]) | Lower max clock limits random access speed; different status register layout affects driver porting effort | Choose when Cypress-compatible toolchain and AEC-Q100 qualification are required for automotive use |
Compared with MX25L8006EM1I-12G and S25FL008KAGMFI011, the W25Q80BVSNIG delivers higher Quad SPI bandwidth, standardized SFDP discovery, and finer 4 KB erase control-making it optimal for resource-constrained XIP designs requiring field-upgradable assets and secure parameter storage.

FAQ
What is the package type and lead count of the W25Q80BVSNIG?
The W25Q80BVSNIG uses an 8-pin SOIC package with 208-mil body width (package code SS). It has gull-wing leads, standard JEDEC outline, and is RoHS-compliant. This package is pin-compatible with other W25Q80BV variants in SOIC-208 format, including W25Q80BVSNIQ and W25Q80BVSFIG.
Does the W25Q80BVSNIG support Quad SPI operation out of the box?
No-the W25Q80BVSNIG requires the Quad Enable (QE) bit in Status Register-2 to be set to '1' before Quad SPI instructions (e.g., EBh, 6Bh) will function. By default, QE=0 after power-up or reset, so /WP and /HOLD remain dedicated hardware control pins until QE is explicitly programmed via Write Status Register (01h) instruction.
How does the /HOLD pin behave in Quad SPI mode on the W25Q80BVSNIG?
In Quad SPI mode (QE=1), the /HOLD pin on the W25Q80BVSNIG functions as IO3-not as a hold control signal. The hold feature is disabled in Quad mode per datasheet specification. To pause transactions, software must rely on /CS deassertion or controller-level flow control, as hardware /HOLD is unavailable when IO3 is active.
What is the minimum erase unit size supported by the W25Q80BVSNIG?
The W25Q80BVSNIG supports 4 KB sector erase as its smallest erase unit, corresponding to one contiguous block of 16 pages (16 × 256 bytes = 4,096 bytes). This granularity enables selective firmware patching and safe parameter updates without affecting adjacent code or configuration regions.
Can the W25Q80BVSNIG be used for secure boot key storage?
Yes-the W25Q80BVSNIG includes three 256-byte security registers with One-Time Programmable (OTP) lock bits (LB1–LB3). Once locked, these registers prevent further writes and are ideal for storing cryptographic keys, device certificates, or root-of-trust seeds used in secure boot chains.
