Winbond Electronics Corporation W25X10VSNIG

Overview

W25X10VSNIG from Winbond is a 1M-bit (128KB) serial Flash memory IC designed for embedded code storage and data logging in space-constrained systems. It features 4KB uniform sectors, dual-output SPI interface supporting up to 75MHz clock (150Mbps effective), and operates from a single 2.7–3.6V supply with 5mA active and 1µA power-down current. It is commonly used in firmware boot storage for microcontrollers in industrial controllers and IoT edge nodes.

For engineers reviewing the W25X10VSNIG datasheet, W25X10VSNIG pinout, W25X10VSNIG application, or W25X10VSNIG equivalent, key selection criteria include sector granularity (4KB), dual-output read performance, hardware/software write protection flexibility, and SOIC-150-mil package compatibility with legacy PCB footprints.

Technical Context

The W25X10VSNIG implements a standard SPI bus compliant with Modes 0 and 3, using four dedicated pins: /CS, CLK, DIO (bidirectional), and DO (dedicated output). Its dual-output capability activates only during Fast Read Dual Output (3Bh) instruction, repurposing DIO as a second data output line to double throughput without altering clock frequency.

Internal architecture includes a 512-page × 256-byte array, programmable via Page Program (02h) with ≤2ms latency per 256-byte page, and erasable in 4KB sectors (20h), 64KB blocks (D8h), or full chip (C7h). Write protection combines volatile WEL bit control, non-volatile BP/TB/SRP bits in status register, and hardware /WP pin assertion.

Key Specifications

FAQ

What is the maximum SPI clock frequency supported by W25X10VSNIG?

W25X10VSNIG supports up to 75 MHz SPI clock frequency in Fast Read Dual Output mode, delivering an effective data rate of 150 Mbps. In standard single-output read mode, it operates reliably at up to 40 MHz. These values are specified under VCC = 2.7–3.6 V and TA = −40°C to +85°C per the June 2007 datasheet Revision L.

Does W25X10VSNIG support dual-output SPI read operations?

Yes, W25X10VSNIG supports dual-output SPI via the Fast Read Dual Output instruction (0x3B). During this command, both DO and DIO pins output alternating data bits on each clock cycle, doubling read throughput without increasing clock frequency. This feature is confirmed in Section 9.1.2 and Table 10.2.9 of the official datasheet.

What package type does W25X10VSNIG use, and what are its dimensions?

W25X10VSNIG uses an 8-pin SOIC 150-mil package (package code SN), with body dimensions of 3.9 mm × 4.9 mm and lead pitch of 1.27 mm. This is explicitly defined in Section 3 ("PIN CONFIGURATION SOIC 150-MIL") and Section 12.1 of the datasheet, and matches the "VSNIG" suffix per Winbond's ordering nomenclature.

How many erase/write cycles does W25X10VSNIG guarantee?

W25X10VSNIG guarantees a minimum of 100,000 program/erase cycles per sector, with 20-year data retention at +85°C. This endurance specification is stated in Section 11.3 ("Endurance and Data Retention") and applies across the full operating temperature range.

Can W25X10VSNIG be used with a 3.3 V microcontroller without level shifters?

Yes, W25X10VSNIG operates natively from 2.7 V to 3.6 V and is fully compatible with 3.3 V logic families. Its input thresholds and output drive levels meet SPI electrical requirements at 3.3 V, eliminating the need for external level-shifting circuitry when interfacing with standard 3.3 V MCUs.
