Product details
Overview
W25Q128JVCIQ from Winbond is a 128M-bit (16MB) serial NOR flash memory with Dual/Quad SPI interface, operating from 2.7V to 3.6V, supporting up to 133MHz clock frequency and 66MB/s continuous read throughput. It features uniform 4KB sectors, 100K program-erase cycles per sector, and 20+ year data retention - deployed in embedded boot code storage, firmware update partitions, and XIP-capable microcontroller systems.
For engineers reviewing the W25Q128JVCIQ datasheet, W25Q128JVCIQ pinout, W25Q128JVCIQ application, or W25Q128JVCIQ equivalent, key selection criteria include Quad SPI enable (QE bit), hardware /RESET availability in TFBGA/SOIC-16 packages, 4KB sector granularity for parameter storage, and JEDEC SFDP compliance for automatic configuration discovery.
Technical Context
The W25Q128JVCIQ implements a standard SPI bus (Mode 0/3) with optional Dual/Quad I/O extensions enabled via non-volatile QE bit in Status Register-2. Its command set includes Fast Read Quad I/O (EBh), enabling 532MHz effective throughput using IO0–IO3 bidirectional pins.
Internal architecture supports concurrent erase/program suspend/resume, individual sector lock via 3×256-byte security registers with OTP locks, and flexible protection schemes including top/bottom block protect (TB), complement array (CMP), and volatile/non-volatile BP bits - all managed through dedicated /WP and /HOLD pins or software commands.

| Max Clock Frequency | 133 MHz (single I/O); 266 MHz equiv. (Dual); 532 MHz equiv. (Quad) |
| Erase Granularity | 4 KB sector / 32 KB block / 64 KB block / full chip - enables fine-grained firmware partitioning |
| Endurance & Retention | 100,000 program-erase cycles per sector; >20 years data retention at +85°C |

| Power Consumption | Typ. 1 µA in power-down mode; active read current <25 mA at 133 MHz |
Pinout & Package
W25Q128JVCIQ uses the 8-pin SOIC 208-mil package (Package Code S), with no dedicated /RESET pin - /HOLD functionality shares Pin 7. All I/O pins support Standard/Dual SPI; Quad SPI requires QE=1, repurposing /WP (Pin 3) as IO2 and /HOLD (Pin 7) as IO3.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; high-impedance DO during deselect; must transition H→L after power-up before first instruction |
| 2 DO (IO1) | Data Output / Quad I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad modes; used for status/data reads |
| 3 /WP (IO2) | Write Protect Input / Quad I/O | Hardware write lock for status register; becomes IO2 when QE=1 - enables Quad SPI data lanes |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; critical for noise immunity in high-speed SPI |
| 5 DI (IO0) | Data Input / Quad I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad modes; carries instructions/addresses |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 (CLK idle low) and Mode 3 (CLK idle high) |
| 7 /HOLD (IO3) | Hold Input / Quad I/O | Pauses ongoing SPI transfer; becomes IO3 when QE=1 - completes Quad I/O lane set (IO0–IO3) |
| 8 VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor required near pin for stable high-frequency operation |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with Wrap-Around Read | Enables true XIP execution via 8/16/32/64-byte wrap modes - reduces address overhead and improves cache efficiency |
| JEDEC SFDP Register | Provides standardized, auto-discoverable configuration parameters (e.g., erase sizes, timing, voltage) - eliminates hard-coded driver assumptions |
| 64-bit Unique ID | Factory-programmed per-device serial number - supports secure firmware binding, device authentication, and field traceability |
| Erase/Program Suspend | Allows background erase or program to be paused for urgent read/write operations - essential for real-time system responsiveness |
| Three 256-byte Security Registers | OTP-lockable storage for keys, certificates, or calibration data - isolated from main array and protected by LB1–LB3 bits |
| Flexible Block Protection | Combines volatile/non-volatile BP bits, TB, SEC, and CMP to define arbitrary protected regions - supports multi-image boot and OTA update safety |
Applications
| Boot Code Storage | Firmware Update Partition |
|---|---|
|
Use Scenario: Storing primary bootloader and application firmware for ARM Cortex-M or RISC-V microcontrollers. IC Role / Device Role / Timing Role: Non-volatile code storage with XIP capability; delivers sequential instruction fetches at up to 66 MB/s via Quad SPI.

Use Scenario: Recording timestamped operational logs (e.g., temperature, pressure, fault codes) in factory automation controllers. IC Role / Device Role / Timing Role: High-endurance cyclic buffer; exploits 100K-cycle endurance and suspend/resume for uninterrupted logging during host interrupts. Use Value: Supports >10-year continuous logging at 100ms intervals without wear leveling controller - reduces firmware complexity. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L12833FZC-10G | 128Mb, 104MHz max clock, no Quad Enable bit; uses legacy SPIMode only - no SFDP or unique ID | Lacks XIP optimization and auto-configuration; suitable for legacy SPI-only designs without security needs | Select when migrating from older Macronix platforms and Quad SPI is not required. |
| S25FL128SAGMFI000 | 128Mb, 133MHz, supports Octal DDR but requires different command set; includes on-die ECC and enhanced security engine | Higher reliability for automotive ECUs; adds ECC correction and secure debug disable - increases driver complexity | Choose for ASIL-B systems needing built-in ECC and certified security features beyond W25Q128JVCIQ scope. |
Compared with MX25L12833FZC-10G, W25Q128JVCIQ delivers faster Quad I/O throughput and standardized SFDP discovery; versus S25FL128SAGMFI000, it offers simpler integration and lower cost where ECC and automotive qualification are unnecessary.

FAQ
What is the package type and pin count of W25Q128JVCIQ?
W25Q128JVCIQ uses an 8-pin SOIC 208-mil package (Package Code S). It has no dedicated /RESET pin; Pin 7 serves as /HOLD in Standard/Dual SPI mode and becomes IO3 in Quad SPI mode when the QE bit is set. This matches the exact marking and mechanical specifications defined in Winbond's W25Q128JV datasheet Revision F.
Does W25Q128JVCIQ support Quad SPI operation out of the box?
No - W25Q128JVCIQ requires explicit configuration to enable Quad SPI. The non-volatile Quad Enable (QE) bit in Status Register-2 must be set to '1' via Write Status Register-2 (31h) instruction. Until then, Pins 3 (/WP) and 7 (/HOLD) remain dedicated hardware control lines, not I/O lanes. This behavior is confirmed in Section 4.2 and Figure 1a of the official datasheet.
How does W25Q128JVCIQ handle power-down and wake-up sequences?
W25Q128JVCIQ enters ultra-low-power mode (<1 µA typical) upon receiving Power-down (B9h) command. Wake-up occurs automatically when /CS transitions low, provided CLK remains stable. No separate release command is needed - the device resumes normal operation within tPUR (1 µs max) after /CS assertion. This sequence is specified in Section 8.2.21 and Table 9.3 of the datasheet.
Can W25Q128JVCIQ be used for secure key storage?
Yes - W25Q128JVCIQ includes three 256-byte Security Registers with One-Time-Programmable (OTP) lock bits (LB1–LB3). Once locked, these registers become read-only and are isolated from main array access. Keys written to them survive power cycles and resist software overwrite attempts - a feature documented in Sections 7.1.3 and 8.2.29–8.2.31 of the datasheet.
What is the minimum erase unit size supported by W25Q128JVCIQ?
W25Q128JVCIQ supports 4KB sector erase as its smallest erasable unit. The memory array contains 4,096 such sectors, enabling precise firmware patching and parameter updates without disturbing adjacent code or data. This granularity is fixed and cannot be subdivided - verified in Section 1 General Descriptions and Figure 2 of the datasheet.
