Product details
Overview
W25X10VSNIG T&R from Winbond is a 1M-bit (128KB) serial flash memory IC with uniform 4KB sectors and dual-output SPI interface, operating from 2.7V to 3.6V, supporting up to 75MHz clock and 150Mbps effective data rate via Fast Read Dual Output (3Bh). It delivers 100,000 program/erase cycles and 20-year data retention, used for code storage, firmware boot, and parameter logging in space-constrained embedded systems.
For engineers reviewing the W25X10VSNIG T&R datasheet, W25X10VSNIG T&R pinout, W25X10VSNIG T&R application, or W25X10VSNIG T&R equivalent, key selection criteria include SOIC-8 150-mil package compatibility, /WP and /HOLD hardware control support, sector-level write protection granularity, and dual-output SPI timing compliance at 75MHz.
Technical Context
The W25X10VSNIG T&R implements a standard SPI bus (Modes 0 and 3) with four dedicated pins-CLK, /CS, DIO, and DO-and supports dual-output operation exclusively during Fast Read Dual Output (3Bh) instruction execution, where DIO functions as a second output. Its internal architecture features a 512-page array (256 bytes/page), organized into 32 erasable 4KB sectors and 2 erasable 64KB blocks.
Write protection combines software-configurable status register bits (BP2–BP0, TB, SRP) with hardware inputs (/WP, /HOLD), enabling top/bottom array locking and status register write disable when /WP is low and SRP = 1. The device enters automatic write-disable state after power-up or any program/erase cycle, requiring explicit Write Enable (06h) before modification.
Key Specifications

| Architecture | Uniform 4KB sectors (32 total) and 64KB blocks (2 total) for flexible data partitioning |
| SPI Interface | Standard and dual-output SPI; Fast Read Dual Output (3Bh) enables 150 Mbps effective throughput |

Pinout & Package
W25X10VSNIG T&R uses an 8-pin SOIC 150-mil (Package Code SN) surface-mount package, pin-compatible with legacy SPI flash footprints and PCB layouts designed for narrow-body SOIC-8.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO and standby power state when high |
| 2 DO | Serial Data Output | Primary output for standard read; outputs MSB-first on falling CLK edge |
| 3 /WP | Write Protect Input | Hardware lock for status register writes when low and SRP = 1 |
| 4 GND | Ground Reference | System ground return path for all I/O and core logic |
| 5 DIO | Serial Data I/O | Input for instructions/addresses; dual-output during Fast Read Dual Output (3Bh) |
| 6 CLK | Serial Clock Input | Edge-triggered timing source; rising edge latches input, falling edge clocks output |
| 7 /HOLD | Hold Input | Pauses ongoing SPI transaction without deselecting device; preserves internal state |
| 8 VCC | Power Supply | 2.7–3.6 V core and I/O supply; requires local decoupling per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Dual-output SPI mode | Enables 150 Mbps effective read bandwidth using DIO as secondary output during 3Bh instruction |
| Hardware write protection | /WP pin combined with SRP bit prevents unintended status register changes under noise or brown-out |
| Flexible sector/block erase | Independent 4KB sector (25 ms) and 64KB block (100 ms) erase commands minimize update latency |
| Auto-write-disable recovery | Automatic WEL clear after every program/erase/write-status cycle eliminates persistent latch risk |
| Top/bottom memory protection | TB bit configures BP2–BP0 to protect upper or lower address region, enabling secure bootloader partitioning |
Applications
| Boot Code Storage | Firmware Over-the-Air (OTA) |
|---|---|
Use Scenario: Storing primary boot loader and initial firmware image executed directly from flash on MCU reset. IC Role / Device Role / Timing Role: Non-volatile code storage with fast sequential read capability via Fast Read Dual Output (3Bh) to reduce boot time.

IC Role / Device Role / Timing Role: High-throughput serial memory providing burst-read access to display resources via Fast Read Dual Output. Use Value: Dual-output SPI delivers sustained 150 Mbps reads, eliminating bottlenecks when loading large bitmap assets from flash to display controller FIFO. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25DF011-SSH-T | 1 M-bit SPI flash; supports 85 MHz clock but lacks dual-output mode; uses different status register map and instruction set | No Fast Read Dual Output; slower effective read bandwidth (~85 Mbps); no /HOLD pin | Select when dual-output is unnecessary and legacy Atmel footprint compatibility is required |
| MX25L1006EZNI-12G | 1 M-bit SPI flash; supports 104 MHz clock and dual-output SPI (3Bh), but requires 2.7–3.6 V and has 50,000-cycle endurance | Higher max clock but lower endurance; identical pinout and instruction compatibility with W25X10 family | Select when higher speed is critical and 50K-cycle lifetime suffices for the use case |
Compared with AT25DF011-SSH-T and MX25L1006EZNI-12G, W25X10VSNIG T&R provides balanced performance with guaranteed 100K-cycle endurance, native /HOLD support for multi-device SPI sharing, and proven dual-output timing at 75 MHz - making it optimal for boot-critical and OTA-update applications demanding reliability and deterministic timing.

FAQ
What is the maximum SPI clock frequency supported by W25X10VSNIG T&R?
W25X10VSNIG T&R supports up to 75 MHz SPI clock frequency in standard and Fast Read modes. When using the Fast Read Dual Output (3Bh) instruction, the effective data transfer rate reaches 150 Mbps due to simultaneous output on DO and DIO pins. This timing is validated per AC Electrical Characteristics section of the June 2007 datasheet, with tV and tQV specifications defined for 75 MHz operation.
Does W25X10VSNIG T&R support hardware write protection independent of software configuration?
Yes, W25X10VSNIG T&R supports hardware write protection via the /WP pin in conjunction with the Status Register Protect (SRP) bit. When SRP = 1 and /WP is driven low, all writes to the status register-including block protection bits-are disabled, even if the Write Enable instruction has been issued. This provides robust immunity against spurious writes during power transients or noise events.
What package type does W25X10VSNIG T&R use, and is it compatible with standard SOIC-8 footprints?
W25X10VSNIG T&R uses an 8-pin SOIC 150-mil package (Package Code SN), with 1.27 mm pitch and 3.9 mm body width. It is fully compatible with industry-standard SOIC-8 land patterns designed for 150-mil width, including IPC-7351B SOIC127P600X215-8 footprint. Pin assignments match Figures 1a and 7 in the datasheet.
How many program/erase cycles and data retention years does W25X10VSNIG T&R guarantee?
W25X10VSNIG T&R guarantees a minimum of 100,000 program/erase cycles and 20 years of data retention at +85°C ambient temperature. These values are specified in Section 11.3 (Endurance and Data Retention) of the official datasheet and apply across the full industrial temperature range (–40°C to +85°C).
Can W25X10VSNIG T&R be used in dual-output SPI mode with existing single-output SPI controllers?
Yes - W25X10VSNIG T&R operates in standard single-output SPI mode by default (using DO only). Dual-output mode is activated exclusively by issuing the Fast Read Dual Output instruction (3Bh); all other instructions, including standard Read (03h) and Fast Read (0Bh), use DO only. Legacy controllers can ignore dual-output functionality and retain full compatibility.
