Product details
Overview
W25Q80DLSNIG TR from Winbond is an 8 M-bit (1 MB) serial NOR flash memory IC supporting standard, dual, and quad SPI interfaces with hardware write protection and 4 KB uniform sector architecture. It operates from 2.3 V to 3.6 V, supports up to 80 MHz dual/quad SPI clocks (160/320 MHz equivalent), delivers 40 MB/s continuous read throughput, and features a 64-bit unique ID and SFDP register for configurable timing. It is used in embedded boot code storage, firmware update partitions, and parameter retention in space-constrained IoT edge nodes.
For engineers reviewing the W25Q80DLSNIG TR datasheet, W25Q80DLSNIG TR pinout, W25Q80DLSNIG TR application, or W25Q80DLSNIG TR equivalent, key selection criteria include its 2.3–3.6 V supply range, SOIC-8 150-mil (SN) package compatibility, Quad Enable (QE) bit dependency for IO2/IO3 functionality, and hardware /WP pin behavior under standard vs. quad mode - all critical for SPI bus sharing, XIP execution, and secure firmware partitioning.
Technical Context
The W25Q80DLSNIG TR implements a SPI-compatible command set with Mode 0 and Mode 3 clock polarity support, enabling interoperability with diverse microcontroller SPI peripherals. Its dual/quad I/O operation relies on bidirectional IO0–IO3 pins, where /WP and /HOLD become IO2 and IO3 only when the non-volatile Quad Enable (QE) bit in Status Register-2 is set - otherwise they retain dedicated hardware protection functions.
Internally, the memory array is organized into 4,096 × 256-byte pages across 256 uniform 4 KB sectors and 16 × 64 KB blocks. Erase/program suspend/resume capability, >100,000 program/erase cycles, and >20-year data retention are confirmed for all sectors. The device includes three 256-byte security registers with OTP lock options and supports JEDEC-standard manufacturer/device ID and 64-bit unique serial number reads.

Pinout & Package
W25Q80DLSNIG TR is supplied in an 8-pin SOIC-150-mil package (package code SN), with gull-wing leads and standard 1.27 mm pitch. Pin 1 is marked by a beveled corner or dot; the package is RoHS-compliant and rated for industrial temperature range (−40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable: high = output tri-stated, low = device active and responsive to SPI commands |
| DO (IO1) | Serial Data Output / Bidirectional I/O1 | Standard SPI output (DO); becomes bidirectional I/O1 in dual/quad mode - requires QE=1 for quad use |
| /WP (IO2) | Write Protect Input / Bidirectional I/O2 | Hardware write lock for status register; repurposed as IO2 only when QE=1 - not available in quad mode if QE=0 |
| GND | Ground Reference | Primary return path for VCC and all I/O signals - must be low-impedance and decoupled near VCC pin |
| VCC | Power Supply | 2.3–3.6 V single supply - requires 100 nF ceramic decoupling capacitor placed within 5 mm of pin |
| /HOLD (IO3) | Hold Input / Bidirectional I/O3 | Pauses ongoing SPI transfer while /CS remains low; becomes IO3 only when QE=1 - disabled during quad operation if QE=0 |
| DI (IO0) | Serial Data Input / Bidirectional I/O0 | Standard SPI input (DI); becomes bidirectional I/O0 in dual/quad mode - required for all instruction writes |
| CLK | Serial Clock Input | Edge-triggered timing reference: rising edge for input sampling, falling edge for output valid - supports Mode 0/3 |
Key Features
| Feature | Design Value |

FAQ
What voltage range does the W25Q80DLSNIG TR support, and why is this important for system design?
The W25Q80DLSNIG TR supports a single supply voltage range of 2.3 V to 3.6 V. This wide range allows direct interfacing with both 2.5 V and 3.3 V logic families without level-shifting circuitry, simplifying power domain design in mixed-voltage systems such as battery-powered IoT nodes or industrial controllers with legacy 2.5 V peripherals. Its 2.3 V lower limit also extends operational life in brown-out conditions where VCC dips transiently.
Does the W25Q80DLSNIG TR support Quad SPI mode, and what configuration is required?
Yes, the W25Q80DLSNIG TR supports Quad SPI mode via Fast Read Quad I/O (EBh) and Fast Read Quad Output (6Bh) instructions, but only after setting the non-volatile Quad Enable (QE) bit in Status Register-2. Once QE=1, the /WP and /HOLD pins become IO2 and IO3 respectively. This configuration is persistent across power cycles and must be performed once during programming - it cannot be toggled dynamically during operation.
How does hardware write protection work on the W25Q80DLSNIG TR, and can it coexist with software protection?
Hardware write protection on the W25Q80DLSNIG TR is implemented via the active-low /WP pin, which locks the status register when asserted - preventing changes to block protect bits or QE configuration. It fully coexists with software protection: the /WP pin controls physical access to the status register, while status register bits (BP0–BP2, TB, SEC) define which memory regions are protected. Both layers must be configured correctly to achieve robust, layered firmware security.
What is the purpose of the 64-bit unique ID in the W25Q80DLSNIG TR, and how is it accessed?
Each W25Q80DLSNIG TR unit contains a factory-programmed, unalterable 64-bit unique serial number used for device-level identification and cryptographic binding. It is accessed via the Read Unique ID Number instruction (4Bh), requiring a 4-byte address dummy cycle followed by 8 bytes of read data. This ID enables secure provisioning, anti-cloning, and firmware-to-hardware attestation in certified IoT and medical devices.
Can the W25Q80DLSNIG TR be used for execute-in-place (XIP) applications, and what performance can be expected?
Yes, the W25Q80DLSNIG TR is optimized for XIP operation using its Quad SPI interface. With 80 MHz clock and Quad I/O, it achieves up to 320 MHz effective throughput and 40 MB/s sustained read rates - sufficient for real-time execution of control algorithms or GUI assets directly from flash. Its uniform 4 KB sectors also allow precise memory mapping and cache line alignment to minimize instruction fetch stalls.
