Product details
Overview
W25Q80BWSNIG from Winbond is an 8 M-bit (1 MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 1.65–1.95 V single-supply operation, 80 MHz max clock frequency, and 4 KB uniform sector architecture. It delivers up to 320 MB/s equivalent bandwidth in Quad I/O mode and supports execute-in-place (XIP) for embedded code storage in space-constrained microcontroller systems.
For engineers reviewing the W25Q80BWSNIG datasheet, W25Q80BWSNIG pinout, W25Q80BWSNIG application, or W25Q80BWSNIG equivalent, key selection criteria include its 8-pin SOIC-150mil (SN) package, hardware /WP and /HOLD pins, Quad Enable (QE) bit requirement for quad mode, and JEDEC-compliant 64-bit unique ID for secure firmware traceability.
Technical Context
The W25Q80BWSNIG implements a SPI command-set compatible with Modes 0 and 3, with dedicated unidirectional DI/DO pins for standard SPI and bidirectional IO0–IO3 for dual/quad modes. Its internal architecture includes a 256-byte page buffer, 256 erasable 4 KB sectors, and 16 erasable 64 KB blocks - enabling flexible data/parameter partitioning.
Quad SPI operation requires non-volatile setting of the QE bit in Status Register-2; once enabled, /WP and /HOLD become IO2 and IO3, disabling hardware write protect and hold functions during quad transactions. The device integrates volatile/non-volatile status register bits, 4×256-byte security registers with OTP locks, and erase/program suspend/resume capability.
Key Specifications

|---|---|
| Memory Density | 8 M-bit (1,048,576 bytes), organized as 4,096 × 256-byte programmable pages |
| Supply Voltage | 1.65 V to 1.95 V - enables low-power operation in battery-backed or ultra-low-voltage MCU systems |
| Max Clock Frequency | 80 MHz - supports 160 MHz (Dual I/O) and 320 MHz (Quad I/O) effective throughput for XIP acceleration |
| Erase Granularity | Uniform 4 KB sectors, 32 KB blocks, 64 KB blocks, and full-chip erase - allows fine-grained firmware update partitioning |

| Interface Protocol | Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3) - selectable via instruction set and QE bit configuration |
| Unique Identifier | 64-bit factory-programmed serial number - enables device-level firmware binding and anti-cloning security |
Pinout & Package
W25Q80BWSNIG uses the 8-pin SOIC-150mil (package code SN) with gull-wing leads, 150-mil body width, and standard JEDEC MS-012AC footprint - compatible with automated SMT assembly and legacy PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable signal; places DO in high-impedance state when deasserted and gates all SPI commands |
| 2 DO (IO1) | Data Output / Bidirectional I/O1 | Unidirectional output in Standard SPI; bidirectional data lane 1 in Dual/Quad SPI; used for Fast Read instructions |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O2 | Hardware lock for Status Register when QE=0; becomes IO2 in Quad mode (QE=1), disabling hardware WP |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for stable SPI timing and noise immunity |
| 5 DI (IO0) | Data Input / Bidirectional I/O0 | Unidirectional input in Standard SPI; bidirectional data lane 0 in Dual/Quad SPI; carries instructions, addresses, and data |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference for all SPI operations; supports Mode 0 and Mode 3 polarity/phase configurations |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O3 | Pauses active SPI transaction when asserted low (QE=0); becomes IO3 in Quad mode (QE=1), disabling HOLD function |
| 8 VCC | Power Supply | 1.65–1.95 V supply; powers core logic, charge pumps, and I/O buffers; requires local 100 nF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Continuous Read Mode | As few as 8 clocks overhead per 24-bit address access - enables true XIP execution with minimal CPU wait states |
| Quad SPI Enable (QE) | Non-volatile Status Register-2 bit that reassigns /WP and /HOLD to IO2/IO3 - required before any Quad I/O instruction |
| Security Registers | Four 256-byte OTP-lockable regions - support secure boot key storage, calibration data, and firmware signature verification |
| Hardware Write Protection | /WP pin + BP0–BP2, TB, SEC, CMP bits - allows selective 4 KB sector locking without software intervention |
| Erase/Program Suspend | 75h/7Ah instructions - permits interruption of long erase/program cycles to service time-critical interrupts, then resume |

FAQ
What is the operating voltage range for W25Q80BWSNIG?
The W25Q80BWSNIG operates from 1.65 V to 1.95 V. This narrow 1.8 V nominal supply range enables low-power operation in battery-powered or energy-harvesting systems. Operation outside this range may cause unreliable read/write behavior or permanent damage. The device includes internal voltage monitoring to prevent writes during brown-out conditions, ensuring data integrity during power transitions.
Does W25Q80BWSNIG support Quad SPI mode out of the box?
No, W25Q80BWSNIG requires explicit configuration to enable Quad SPI mode. The non-volatile Quad Enable (QE) bit in Status Register-2 must be set using the Write Status Register (01h) instruction. Until QE=1, pins /WP and /HOLD remain functional as hardware controls; after enabling QE, they become IO2 and IO3, and Quad I/O instructions like EBh become active.
How many program/erase cycles does W25Q80BWSNIG guarantee?
W25Q80BWSNIG guarantees a minimum of 100,000 program/erase cycles per sector. This endurance rating applies to all 256 erasable 4 KB sectors across the full memory array. Field data indicates typical performance exceeds 200,000 cycles, supporting frequent firmware updates in remote or inaccessible deployments without premature wear-out concerns.
Can W25Q80BWSNIG be used for execute-in-place (XIP) applications?
Yes, W25Q80BWSNIG supports true XIP via its Continuous Read Mode and Fast Read Quad I/O (EBh) instruction. With as few as 8 clock cycles overhead per address, it delivers deterministic latency for instruction fetches directly from flash. This eliminates need for RAM shadowing in resource-limited MCUs and reduces boot time in real-time systems using Dual or Quad SPI interfaces.
What package type does W25Q80BWSNIG use?
W25Q80BWSNIG uses the 8-pin SOIC-150mil package (package code SN), measuring 3.9 mm × 4.9 mm with 1.27 mm lead pitch. This JEDEC-standard gull-wing package ensures compatibility with legacy PCB footprints, automated optical inspection, and reflow soldering processes common in high-volume manufacturing of industrial and consumer electronics.
