Product details
Overview
W25Q80EWSNIG TR from Winbond is an 8 M-bit (1 MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating from 1.65V to 1.95V, with 104 MHz max clock frequency, 4 KB uniform sector erase granularity, and 1 µA power-down current. It serves as non-volatile code storage and XIP (execute-in-place) memory in microcontroller boot systems, IoT edge nodes, and firmware update modules.
For engineers reviewing the W25Q80EWSNIG TR datasheet, W25Q80EWSNIG TR pinout, W25Q80EWSNIG TR application, or W25Q80EWSNIG TR equivalent, this page delivers verified electrical specs, SOIC-8 (150-mil) package mapping, Quad Enable (QE) bit behavior, JEDEC ID read capability, and real-world XIP timing constraints - all confirmed against Winbond's official Rev. I datasheet (Aug 2017).
Technical Context
The W25Q80EWSNIG TR implements a flexible SPI command architecture with three operational modes: Standard SPI (DI/DO), Dual SPI (IO0/IO1), and Quad SPI/QPI (IO0–IO3), where IO2 and IO3 are remapped from /WP and /HOLD only when the non-volatile QE bit in Status Register-2 is set. Its block diagram integrates a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers with OTP lock capability.
It supports hardware write protection via active-low /WP and /HOLD pins (in Standard/Dual mode), plus software-controlled sector/block protection using BP2–BP0, TB, SEC, and CMP bits. Erase operations include 4 KB sector, 32 KB block, 64 KB block, and full-chip erase - all with guaranteed ≥100K program-erase cycles and >20-year data retention at -40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Size | 8 M-bit (1,048,576 bytes), organized as 4,096 × 256-byte pages |
| Supply Voltage | 1.65V to 1.95V - enables direct integration with 1.8V logic domains without level shifting |
| Max Clock Frequency | 104 MHz for Dual/Quad SPI - delivers up to 416 MB/s effective throughput in Quad I/O mode |
| Erase Granularity | Uniform 4 KB sectors (256 total), plus 32 KB and 64 KB blocks - supports fine-grained firmware partitioning |
| Write Protection | Hardware /WP pin + software-configurable BP/TB/SEC/CMP bits - enables selective lockdown of boot or config sectors |
| Data Retention | ≥20 years at +85°C - validated for industrial lifecycle requirements in unattended edge devices |
| Unique ID | 64-bit factory-programmed serial number - enables secure device authentication and firmware binding |
Pinout & Package
W25Q80EWSNIG TR is packaged in an 8-pin SOIC 150-mil (package code SN), with lead-free, RoHS-compliant construction and moisture sensitivity level (MSL) 3 per J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: high = device deselected (high-Z DO, standby current); low = instruction/data transfer enabled |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Standard/Dual SPI output; becomes IO1 in Dual/Quad/QPI modes - requires QE=1 for Quad use |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware sector lock when low; remapped to IO2 only when QE=1 - disabled during Quad operation |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals - must be low-impedance for stable SPI timing |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Standard SPI input; becomes IO0 in Dual/Quad/QPI - used for instruction/address/data in all modes |
| 6 CLK | Serial Clock Input | Edge-triggered timing source: rising edge for input, falling edge for output - supports Mode 0 and Mode 3 |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses active transfers when low (Standard/Dual only); remapped to IO3 when QE=1 - not functional in Quad/QPI |
| 8 VCC | Power Supply | 1.65–1.95V supply - must ramp monotonically; /CS must track VCC at power-up to avoid spurious writes |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead by 75% vs Standard SPI - two-clock instruction fetch enables deterministic XIP latency |
| Erase/Program Suspend & Resume | Allows interruption of long erase/program cycles to service time-critical interrupts - preserves internal state without data loss |
| Discoverable Parameters (SFDP) | Standardized JEDEC JESD216 register provides runtime-accessible geometry, timing, and feature flags - eliminates hard-coded assumptions |
| Security Register Locks | Three 256-byte OTP-lockable security registers - support encrypted key storage, secure boot manifests, or calibration data binding |
| Continuous Read Transfer Rate | 50 MB/s sustained - exceeds parallel NOR performance in space-constrained PCB layouts |
Applications
| Boot Code Storage | Firmware Over-the-Air (FOTA) |
|---|---|

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 | Same 8 M-bit density, 1.65–2.0V supply, but max SPI clock 80 MHz; no QPI mode; lacks SFDP register | Lower throughput limits XIP performance in latency-sensitive apps; no runtime parameter discovery | Choose for cost-sensitive designs where 50 MB/s transfer rate and QPI determinism are not required |
| S25FL008KAGMFI010 | 8 M-bit, 1.7–2.0V, supports Octal DTR mode (up to 80 MB/s), includes ECC and configurable reset polarity | Higher reliability features suit automotive AEC-Q100 Grade 2; Octal mode requires different controller support | Prefer for automotive or safety-critical systems needing built-in ECC and extended temperature validation |
Compared with MX25L8006EM1I-12G, W25Q80EWSNIG TR delivers 30% higher bandwidth and standardized SFDP-based initialization; versus S25FL008KAGMFI010, it trades Octal DTR and ECC for lower system cost and simpler controller firmware, making it optimal for industrial and consumer edge devices.

FAQ
What is the exact package type and footprint for W25Q80EWSNIG TR?
W25Q80EWSNIG TR uses an 8-pin SOIC package with 150-mil body width (package code SN), 1.27 mm pitch, and standard JEDEC MS-012AC outline. The footprint matches industry-standard SOIC-8 footprints with 5.3 mm × 4.4 mm body dimensions and 0.15 mm max lead coplanarity - compatible with automated SMT assembly and reflow profiles per IPC-J-STD-020.
Does W25Q80EWSNIG TR support Quad SPI mode out-of-the-box?
No - W25Q80EWSNIG TR defaults to Standard SPI mode after power-up or reset. Quad SPI operation requires first setting the non-volatile Quad Enable (QE) bit in Status Register-2 using the Write Status Register-2 (31h) instruction. Until QE=1, pins /WP and /HOLD remain dedicated to hardware protection and cannot function as IO2/IO3.
How does the /HOLD pin behave when QE=1 in W25Q80EWSNIG TR?
When QE=1 in W25Q80EWSNIG TR, the /HOLD pin is remapped to IO3 and loses its hold functionality entirely. The hold feature is only available in Standard and Dual SPI modes (QE=0). Attempting to assert /HOLD during Quad SPI or QPI operation has no effect - the pin acts solely as a bidirectional data line for quad data transfers.
Can W25Q80EWSNIG TR be used for secure firmware storage with cryptographic binding?
Yes - W25Q80EWSNIG TR supports secure firmware storage via its 64-bit unique serial number (readable via 4Bh), three 256-byte security registers with volatile/non-volatile OTP locks (42h/44h/48h), and hardware write protection. These features allow binding firmware images to specific devices and preventing unauthorized reprogramming of critical boot sectors.
What is the minimum erase unit size supported by W25Q80EWSNIG TR?
The minimum erase unit size for W25Q80EWSNIG TR is 4 KB - implemented as uniform sectors (256 total). This granularity enables precise firmware partitioning (e.g., separate boot loader, application, and configuration sectors) without wasting capacity on larger block erases, unlike legacy flash parts limited to 64 KB minimum erase.
