Product details
Overview
W25Q64FVZEIG TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC designed for code storage and data logging in space-constrained embedded systems. It supports Standard/Dual/Quad SPI and QPI interfaces, delivers up to 104 MHz clock rate (416 MHz equivalent Quad I/O), operates from 2.7–3.6 V, and features 4 KB uniform sectors, 20-year data retention, and hardware write protection via /WP and /HOLD pins. It is commonly used in microcontroller boot code storage and firmware update storage.
For engineers reviewing the W25Q64FVZEIG TR datasheet, W25Q64FVZEIG TR pinout, W25Q64FVZEIG TR application, or W25Q64FVZEIG TR equivalent, key selection criteria include Quad SPI XIP capability, JEDEC ID and SFDP register support, sector-level erase granularity, security register availability, and compatibility with industrial temperature range (-40°C to +85°C) designs.
Technical Context
The W25Q64FVZEIG TR implements a flexible SPI-compatible command set with dedicated instructions for Fast Read Dual/Quad I/O (3Bh/6Bh/BBh/EBh), Quad Input Page Program (32h), and QPI mode entry (38h). Its architecture includes three 256-byte Security Registers with OTP locks, a 64-bit Unique ID, and SFDP (Serial Flash Discoverable Parameters) register for automatic configuration discovery.
It uses non-volatile status registers with configurable Block Protect (BP2–BP0), Top/Bottom (TB), Sector Protect (SEC), and Quad Enable (QE) bits. QE=1 reassigns /WP and /HOLD to IO2 and IO3, enabling full Quad I/O operation - a hardware-configurable mode requiring explicit instruction-based enable/disable sequences.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 M-bit (8 MB); enables full MCU boot image storage without external parallel bus. |
| Interface Modes | Standard SPI, Dual SPI, Quad SPI, and QPI; allows scalable bandwidth from 104 MHz (single-line) to 416 MHz equivalent (quad-line). |
| Erase Granularity | Uniform 4 KB sectors (2,048 total), plus 32 KB and 64 KB blocks; supports fine-grained firmware partitioning and OTA update safety. |
| Write Endurance | 100,000 program/erase cycles per sector; suitable for frequent field firmware updates in industrial controllers. |
| Data Retention | 20 years at +85°C; validated for long-lifecycle deployments in automotive infotainment and medical devices. |

Pinout & Package
W25Q64FVZEIG TR is packaged in an 8-pad WSON 8x6-mm (JEDEC MO-241AC, package code ZE), with exposed pad for thermal dissipation and footprint compatibility across Winbond's W25Q family.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable signal; must transition high→low before instruction acceptance; controls device power state (standby vs active). |
| DO (IO1) | Serial Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; becomes bidirectional IO1 in Dual/Quad modes; supports fast read and status polling. |
| /WP (IO2) | Hardware Write Protect / Bidirectional I/O | Active-low hardware lock for status registers; repurposed as IO2 when Quad Enable (QE) bit is set - disables hardware WP in Quad mode. |
| GND | Ground Reference | Primary return path for all I/O and core logic; requires low-impedance connection to minimize noise coupling into SPI timing. |
| DI (IO0) | Serial Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; becomes bidirectional IO0 in Dual/Quad modes; carries commands, addresses, and program data. |
| CLK | Serial Clock Input | Master-synchronized timing reference; supports SPI modes 0 and 3; max 104 MHz frequency defines real-time throughput ceiling. |
| /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing SPI transaction while /CS remains low; repurposed as IO3 when QE=1 - disables hold function in Quad mode. |
| VCC | Power Supply | Single 2.7–3.6 V supply powers core logic, charge pumps, and I/O buffers; decoupling capacitor required near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per byte in QPI mode, enabling true execute-in-place (XIP) from flash without RAM copy. |
| Continuous Read Mode | Supports wrap lengths of 8/16/32/64 bytes with only 8-clock address overhead, optimizing sequential access for streaming firmware or audio. |
| Erase/Program Suspend & Resume | Allows background interrupt handling during long erase operations (e.g., 64 KB block erase ~200 ms), critical for real-time system responsiveness. |
| JEDEC Manufacturer & Device ID | Enables automated flash detection and initialization in bootloader code using standard 90h/9Fh commands - no vendor-specific probing needed. |
| Software/Hardware Write Protection | Combines volatile/non-volatile status register bits (BP2–BP0, TB, SEC) with physical /WP pin for layered protection against accidental writes. |
| Discoverable Parameters (SFDP) | Provides standardized register (5Ah) describing erase sizes, timing, and feature flags - eliminates hardcoded assumptions in HAL/firmware. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L6433FZNI-10G | 64 M-bit, 104 MHz max, SOIC-8 and WSON-8 packages; lacks QPI mode and SFDP register. | No native execute-in-place support; requires software-managed instruction toggling instead of QPI's 2-clock efficiency. | Prefer W25Q64FVZEIG TR when XIP, SFDP auto-configuration, or security registers are required. |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max, supports HyperBus but not QPI; includes ECC and configurable latency. | Higher reliability for mission-critical logging but lower bandwidth than W25Q64FVZEIG TR's 416 MHz Quad I/O. | Choose W25Q64FVZEIG TR for cost-sensitive, high-throughput boot storage; select S25FL164K0XMFI010 only if ECC or HyperBus interface is mandatory. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64FVZEIG TR uniquely combines QPI mode, SFDP register, and three OTP-locked Security Registers - making it optimal for secure, high-speed boot and firmware update architectures where instruction efficiency and identity binding are design-critical.

FAQ
What is the maximum clock frequency supported by W25Q64FVZEIG TR in Quad SPI mode?
The W25Q64FVZEIG TR supports up to 104 MHz on the CLK pin in Quad SPI mode, delivering an effective data rate of 416 Mbps (104 MHz × 4 lines). This is confirmed in the "AC Electrical Characteristics" section (Table 8.6) of the official datasheet, with timing validated under VCC = 2.7–3.6 V and TA = -40°C to +85°C conditions. The W25Q64FVZEIG TR achieves this using Fast Read Quad I/O (6Bh) and Quad Input Page Program (32h) instructions.
Does W25Q64FVZEIG TR support execute-in-place (XIP) operation?
Yes, the W25Q64FVZEIG TR supports true XIP via Continuous Read Mode and Quad Peripheral Interface (QPI). When enabled (via 38h instruction), QPI reduces instruction overhead to two clocks per byte, allowing direct CPU execution from flash without RAM buffering. This is explicitly documented in Section 2 ("Features") and Section 6.1.4 ("QPI Instructions") of the datasheet, and validated by its use in ARM Cortex-M bootloaders.
How is hardware write protection implemented on W25Q64FVZEIG TR?
Hardware write protection on the W25Q64FVZEIG TR uses the /WP pin (active-low) in conjunction with non-volatile status register bits (BP2–BP0, TB, SEC, CMP). When /WP is held low and BP bits are set, writes to protected sectors or status registers are blocked. However, /WP is reassigned to IO2 in Quad SPI mode (when QE=1), so hardware protection is only active in Standard or Dual SPI configurations unless software-based BP locking is used concurrently.
What package type does W25Q64FVZEIG TR use, and is it pin-compatible with other W25Q64 variants?
W25Q64FVZEIG TR uses an 8-pad WSON 8x6-mm package (JEDEC MO-241AC, package code ZE). It shares identical pinout and electrical characteristics with other W25Q64FV variants in WSON-8 (e.g., ZP, ZE), SOIC-8 (SS), and PDIP-8 (DA) packages - confirmed in Sections 3.1–3.4 and Table 9.5 of the datasheet. Pin compatibility extends across all 8-pin variants, enabling drop-in replacement within same package footprint.
Does W25Q64FVZEIG TR include unique device identification?
Yes, the W25Q64FVZEIG TR includes a factory-programmed, unalterable 64-bit Unique ID accessible via the Read Unique ID Number instruction (4Bh). This ID is guaranteed unique per die and is used for secure boot binding, device authentication, and firmware licensing - detailed in Section 7.2.33 and Feature List Section 2 of the datasheet.
