Product details
Overview
W25X10CLZPIG from Winbond is a 1 M-bit (128 KB) serial flash memory IC supporting standard SPI, dual-output SPI, and dual I/O SPI interfaces with 4 KB uniform sectors, 104 MHz clock operation, and true execute-in-place (XIP) capability via Continuous Read Mode - used for code storage, firmware boot, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25X10CLZPIG datasheet, W25X10CLZPIG pinout, W25X10CLZPIG application, or W25X10CLZPIG equivalent, this page delivers verified electrical specs, SOIC-8 and USON-2x3-mm package mapping, hardware/software write protection logic, dual I/O timing behavior, and real-world selection guidance against functionally aligned alternatives.
Technical Context
The W25X10CLZPIG implements a SPI-compatible serial flash architecture with dual I/O mode enabled via BBh instruction, using bidirectional IO0/IO1 pins for address/data transfer at up to 208 Mbps equivalent throughput. It supports SPI modes 0 and 3, with /CS tracking required during power-up to prevent spurious writes.
Its internal status register includes non-volatile BP1/BP0 and TB bits for configurable top/bottom 4 KB–64 KB memory protection, coupled with volatile WEL and BUSY flags. Write protection is enforced by both software (SRP + BP bits) and hardware (/WP pin low), with automatic WEL clearing after program/erase completion.

Pinout & Package
W25X10CLZPIG is available in two RoHS-compliant packages: 8-pin SOIC-150-mil (package code SN) and 8-pad USON 2×3-mm (package code UX). Both share identical pin functions and signal mapping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; must track VCC at power-up; high-impedance DO when deasserted |
| DO (IO1) | Serial Data Output / Dual I/O | Unidirectional output in standard SPI; bidirectional I/O in dual SPI (BBh/3Bh) |
| /WP | Hardware Write Protect Input | Active-low; locks status register when SRP=1, enabling hardware-enforced read-only mode |
| GND | Ground Reference | Signal and power return path; requires low-impedance connection to minimize noise coupling |
| DI (IO0) | Serial Data Input / Dual I/O | Unidirectional input in standard SPI; bidirectional I/O in dual SPI (BBh/3Bh) |
| CLK | Serial Clock Input | Edge-triggered timing source; supports modes 0 and 3; must be stable before /CS assertion |
| /HOLD | Operation Pause Control | Active-low; suspends ongoing SPI transaction without resetting internal state - useful in multi-device bus sharing |
| VCC | Power Supply | 2.3–3.6 V supply; decoupling capacitor (0.1 µF) required within 10 mm of pin for stable operation |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AT25DF021A-SSHN-B | 2 M-bit density, 3.0–3.6 V supply only, no dual I/O mode, supports 85 MHz max clock | Lacks BBh instruction and Continuous Read Mode - limits XIP performance and increases instruction overhead | Choose when higher density is needed and dual I/O bandwidth is not required; verify /WP and /HOLD timing compatibility |
| S25FL032A0XMFI001 | 32 M-bit density, quad SPI support, 1.7–2.0 V and 2.7–3.6 V dual supply, 80 MHz max clock | Quad SPI interface adds pin count and complexity; no native dual I/O mode like W25X10CLZPIG's BBh | Prefer for scalable designs needing future capacity headroom; avoid if pin count or 2.3–3.6 V single-supply operation is mandatory |
Compared with AT25DF021A-SSHN-B and S25FL032A0XMFI001, the W25X10CLZPIG delivers optimal balance of 1 M-bit capacity, 2.3–3.6 V single-supply operation, dual I/O bandwidth, and ultra-low power-down current - making it ideal for compact, battery-aware, and cost-sensitive embedded systems where precise 4 KB sector control and XIP efficiency are design priorities.

FAQ
What is the maximum clock frequency supported by W25X10CLZPIG in dual I/O mode?
The W25X10CLZPIG supports up to 104 MHz clock frequency in dual I/O mode using the BBh instruction, delivering an effective data transfer rate of 208 Mbps. This is confirmed in Section 9.6 AC Electrical Characteristics of the datasheet, where tV and tVH timing parameters are specified for CLK ≤104 MHz. The device maintains full functionality and timing compliance at this rate across its −40°C to +85°C operating range. W25X10CLZPIG does not support higher frequencies in dual I/O mode.
Does W25X10CLZPIG support execute-in-place (XIP) operation?
Yes, W25X10CLZPIG supports true XIP operation via its Continuous Read Mode, which reduces instruction overhead to as few as 16 clocks per 24-bit address. This allows microcontrollers to fetch and execute code directly from the flash without copying to RAM. The feature is enabled using the Fast Read Dual Output (3Bh) or Fast Read Dual I/O (BBh) instructions, and is explicitly documented in Section 1 General Description and Section 7.1.2 Dual SPI Instructions of the datasheet. W25X10CLZPIG's low latency and deterministic timing make it suitable for real-time XIP use cases.
What package types are available for W25X10CLZPIG?
W25X10CLZPIG is offered in two package variants: 8-pin SOIC-150-mil (package code SN) and 8-pad USON 2×3-mm (package code UX). Both packages share identical pinout and electrical characteristics, as confirmed in Sections 3, 4, and 5.1 of the datasheet. The ZPIG suffix specifically denotes the USON 2×3-mm package with lead-free, halogen-free, and RoHS-compliant construction. No other package types (e.g., TSSOP, WSON, or KGD) are listed for W25X10CLZPIG in the official ordering information.
How does hardware write protection work on W25X10CLZPIG?
Hardware write protection on W25X10CLZPIG is implemented via the /WP pin in conjunction with the Status Register Protect (SRP) bit. When SRP = 1 and /WP is driven low, writes to the status register (including BP and TB bits) are locked out - preventing accidental reconfiguration of memory protection. This behavior is detailed in Section 8.1.6 and Table on page 11 of the datasheet. The /WP pin has no effect when SRP = 0 (factory default), allowing full software control. W25X10CLZPIG requires both conditions to be met for hardware-enforced protection.
What is the endurance and data retention specification for W25X10CLZPIG?
W25X10CLZPIG guarantees ≥100,000 program/erase cycles per sector and ≥20 years of data retention at +25°C, as stated in Section 2 Features and confirmed in Section 9.4 DC Electrical Characteristics of the datasheet. These values are measured under standard operating conditions (VCC = 2.7–3.6 V, TA = 25°C) and apply uniformly across all 4 KB sectors. The 20-year retention is not derated for temperature - actual retention at +85°C is ≥10 years per JEDEC JESD22-A117 stress testing methodology. W25X10CLZPIG does not specify accelerated retention at elevated temperatures beyond this.
