Product details
Overview
W25Q80EWSVIG 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, 4 KB uniform sector erase, and 1 µA power-down current. It serves as non-volatile code storage and XIP execution memory in space-constrained embedded systems.
For engineers reviewing the W25Q80EWSVIG TR datasheet, W25Q80EWSVIG TR pinout, W25Q80EWSVIG TR application, or W25Q80EWSVIG TR equivalent, key selection considerations include Quad Enable bit configuration, /WP and /HOLD pin reassignment in Quad mode, 4 KB sector granularity for firmware partitioning, and JEDEC-compliant SFDP register support for auto-configuration.
Technical Context
The W25Q80EWSVIG 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). Mode switching requires explicit instruction execution (e.g., 38h to enter QPI) and non-volatile QE bit setting in Status Register-2.
Its memory array comprises 4,096 × 256-byte pages organized into 256 erasable 4 KB sectors and 16 erasable 64 KB blocks. Erase/program suspend/resume capability enables concurrent background operations, while hardware write protection uses /WP pin + status register bits (BP2–BP0, TB, SEC) for top/bottom/complement array locking.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 8 M-bit (1,048,576 bytes), enabling compact firmware storage for microcontrollers with limited PCB area. |
| Supply Voltage | 1.65V–1.95V single supply, compatible with 1.8V logic domains without level shifting. |
| Max Clock Frequency | 104 MHz SPI clock; supports 208 MHz dual-I/O and 416 MHz quad-I/O effective throughput for fast code shadowing. |
| Erase Granularity | Uniform 4 KB sectors (256 total), allowing fine-grained firmware update partitioning without disturbing adjacent code/data. |
| Write Endurance | Minimum 100,000 program-erase cycles per sector, supporting field firmware upgrades over product lifetime. |
| Data Retention | 20+ years at +25°C, ensuring long-term reliability in industrial and automotive applications. |
| Power Consumption | 1 mA active current; <1 µA power-down current, critical for battery-powered IoT edge nodes. |
Pinout & Package
W25Q80EWSVIG TR is packaged in an 8-pin VSOP 150-mil (package code SV), with lead-free, RoHS-compliant construction and surface-mount compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable signal; device enters high-impedance output state when high, reducing bus contention in multi-device SPI systems. |
| 2 DO (IO1) | Data Output / I/O1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad SPI/QPI; used for read data and status feedback. |
| 3 /WP (IO2) | Write Protect Input / I/O2 | Hardware lock for status register writes when QE=0; becomes IO2 in Quad mode (QE=1), disabling hardware WP function. |
| 4 GND | Ground Reference | Signal and power return path; must be low-impedance to maintain timing integrity and noise immunity during high-speed reads. |
| 5 DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad SPI/QPI; carries instructions, addresses, and program data. |
| 6 CLK | Serial Clock Input | Master-generated timing reference; supports SPI modes 0 and 3; edge-triggered for instruction/data latching. |
| 7 /HOLD (IO3) | Hold Input / I/O3 | Pauses ongoing SPI transaction when low (CS active); becomes IO3 in Quad mode (QE=1), disabling hold functionality. |
| 8 VCC | Power Supply | 1.65–1.95V core supply; decoupling capacitor required near pin to suppress switching noise and ensure stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead by transmitting 8-bit opcodes in 2 clocks (vs. 8 in SPI), accelerating XIP boot sequences in resource-limited SoCs. |
| Erase/Program Suspend & Resume | Allows interruption of long erase/program operations to service time-critical interrupts, then resumption without data loss or corruption. |
| 64-bit Unique Serial Number | Enables device-level traceability and secure firmware binding in certified industrial and medical systems. |
| SFDP Register Support | Provides standardized, read-only parameter table for automatic driver initialization-eliminating hardcoded timing values in bootloader code. |
| 3×256-byte Security Registers | OTP-lockable storage for cryptographic keys or calibration data, isolated from main array to prevent accidental overwrite during firmware updates. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L8006EM1I-12G | Same 8 M-bit density, 1.65–1.95V supply, and SOIC/VSOP packaging; supports only Standard/Dual SPI (no QPI or Quad I/O). | Lacks Quad SPI and QPI modes, limiting maximum read throughput to ~104 MB/s vs. 416 MB/s on W25Q80EWSVIG TR. | Select when QPI/XIP acceleration is unnecessary and cost sensitivity outweighs performance needs. |
| S25FL008K0XMFI011 | 8 M-bit, 1.7–2.0V supply, supports Quad SPI and QPI; includes built-in ECC and configurable dummy cycles not present in W25Q80EWSVIG TR. | Higher reliability for extended temperature operation (+105°C), but larger 8-pin SOIC 208-mil footprint vs. VSOP 150-mil. | Prefer for automotive under-hood applications where extended temp range and ECC are mandatory. |
Compared with MX25L8006EM1I-12G and S25FL008K0XMFI011, the W25Q80EWSVIG TR delivers superior quad-I/O throughput and compact VSOP packaging, making it optimal for space-constrained, high-performance embedded designs requiring flexible interface modes and low-power operation.

FAQ
What interface protocols does the W25Q80EWSVIG TR support?
The W25Q80EWSVIG TR supports Standard SPI (4-wire), Dual SPI (4-wire), Quad SPI (6-wire), and Quad Peripheral Interface (QPI, 6-wire). QPI mode requires issuing the Enter QPI (38h) instruction after setting the Quad Enable (QE) bit in Status Register-2. All modes operate within the same 1.65–1.95V supply range and share identical pin assignments on the VSOP package.
How is hardware write protection implemented on the W25Q80EWSVIG TR?
Hardware write protection on the W25Q80EWSVIG TR uses the /WP pin in conjunction with Block Protect (BP2–BP0), Top/Bottom (TB), Sector Protect (SEC), and Complement Protect (CMP) bits in the status register. When /WP is pulled low and QE=0, status register writes are inhibited. The /WP pin becomes IO2 in Quad mode (QE=1), disabling this hardware lock-so software-based protection must then be used.
What is the significance of the 64-bit Unique Serial Number in the W25Q80EWSVIG TR?
The 64-bit Unique Serial Number in the W25Q80EWSVIG TR is factory-programmed and read-only, enabling device-level traceability, secure firmware binding, and anti-counterfeiting measures. It is accessed via the Read Unique ID Number (4Bh) instruction and remains unchanged across program/erase cycles, supporting regulatory compliance in medical and industrial applications.
Can the W25Q80EWSVIG TR perform erase or program operations while servicing interrupts?
Yes-the W25Q80EWSVIG TR supports Erase/Program Suspend and Resume functions. By issuing the Erase/Program Suspend (75h) instruction, ongoing operations pause and release the SPI bus, allowing the host MCU to handle time-critical interrupts. After servicing, Resume (7Ah) restores the suspended operation without data loss or requiring restart.
What package type does the W25Q80EWSVIG TR use, and how does it differ from other W25Q80EW variants?
The W25Q80EWSVIG TR uses an 8-pin VSOP 150-mil package (package code SV), distinguished by its 150-mil body width and gull-wing leads. This differs from SOIC 208-mil (SS), WSON 6x5-mm (ZP), USON 2x3-mm (UX), and WLCSP (BY) variants-each with distinct thermal, mechanical, and layout requirements. The SV variant offers optimal balance of hand-solderability, board space, and thermal performance for industrial PCBs.
