Product details
Overview
W25Q64JVDAIQ TR from Winbond is a 64M-bit (8MB) serial NOR flash memory with Quad SPI interface, supporting up to 133 MHz clock frequency and 532 MB/s equivalent Quad I/O throughput. It features uniform 4KB sectors, 32KB/64KB blocks, 256-byte page programming, hardware /RESET on SOIC-16 and TFBGA packages, and integrated security registers. It is used for code execution in place (XIP), firmware storage, and parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q64JVDAIQ TR datasheet, W25Q64JVDAIQ TR pinout, W25Q64JVDAIQ TR application, or W25Q64JVDAIQ TR equivalent, this page delivers verified electrical specs, package mapping to DA (8-pin PDIP 300-mil), confirmed Quad SPI timing behavior, JEDEC ID compliance, and real-world XIP and firmware update use cases - all validated against Winbond's official Revision C datasheet (June 2016).
Technical Context
The W25Q64JVDAIQ TR implements a standard SPI bus with Mode 0 and Mode 3 support, plus Dual and Quad SPI instruction sets requiring explicit QE bit enablement in Status Register-2. Its internal architecture includes a 256-byte page buffer, sector/block erase logic, and three 256-byte security registers accessible via dedicated instructions (42h/44h/48h).
It supports hardware reset via /RESET pin (available only on SOIC-16 and TFBGA packages), while the DA package variant uses software reset (66h + 99h). Write protection relies on volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP), OTP lock options (special order), and power-down state retention.

| Individual Sector Lock | Per-sector write protection via 36h/39h instructions - isolates bootloader region from application firmware corruption |
| SFDP Register | JEDEC-standard Serial Flash Discoverable Parameters (5Ah) enables automatic driver configuration without hard-coded timing values |
| Wrap-Around Burst | Set Burst with Wrap (77h) allows continuous sequential reads across page boundaries without address wrap interruption - simplifies DMA streaming |
Applications
| Bootloader Storage | Firmware Over-the-Air (OTA) |
|---|---|
Use Scenario: Storing immutable bootloader code in embedded devices where recovery from corrupted application firmware is essential. IC Role / Device Role / Timing Role: Non-volatile code storage with hardware-level write protection (BP bits, SEC, TB) preventing accidental overwrite during field updates. Use Value: Ensures system always boots reliably; supports dual-bank OTA by locking one sector while updating the other. | Use Scenario: Receiving encrypted firmware images over low-bandwidth wireless links (e.g., NB-IoT, LoRaWAN) and verifying integrity before installation. IC Role / Device Role / Timing Role: Secure storage of signed firmware binaries and cryptographic keys in OTP security registers. Use Value: Enables authenticated, tamper-resistant updates without external secure elements - reduces BOM cost and PCB area. |
| Industrial HMI Configuration | Automotive Diagnostic Module |
Use Scenario: Retaining user-specific display layouts, calibration offsets, and language settings across power cycles in human-machine interface panels. IC Role / Device Role / Timing Role: Parameter storage with 4KB sector granularity enabling fine-grained wear leveling and fast individual setting updates. Use Value: Eliminates need for battery-backed SRAM; supports >100K write cycles per sector for daily configuration changes over 10+ years. | Use Scenario: Logging diagnostic trouble codes (DTCs), sensor calibration data, and event timestamps in automotive-grade telematics units. IC Role / Device Role / Timing Role: High-reliability data logger with -40°C to +85°C operation, power-loss-safe write sequencing, and ECC-capable read paths. Use Value: Meets AEC-Q100 stress requirements for non-safety-critical modules; supports deterministic 133 MHz read bursts for real-time DTC retrieval. |
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 clock, no hardware /RESET, different SFDP layout, no security registers | Lacks OTP security registers and Quad I/O suspend/resume; supports only standard/dual SPI out-of-box | Choose when security and Quad-mode suspend are not required; verify SFDP parser compatibility |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max clock, Cypress-compatible command set, no /RESET on PDIP, no unique ID | Lower max frequency limits XIP performance; lacks 64-bit unique ID and individual sector lock commands | Prefer for legacy Cypress ecosystem designs; avoid if 133 MHz throughput or device authentication is needed |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, W25Q64JVDAIQ TR delivers higher Quad SPI bandwidth (532 MB/s vs ≤208 MB/s), integrated security registers for key storage, and deterministic erase/program suspend - making it optimal for secure, real-time firmware update architectures.

FAQ
Does W25Q64JVDAIQ TR support hardware reset via /RESET pin?
No, W25Q64JVDAIQ TR uses the DA (8-pin PDIP 300-mil) package, which does not include a /RESET pin. Hardware reset is only available on SOIC-16 (SF) and TFBGA (TB/TC) packages. For W25Q64JVDAIQ TR, system reset must be implemented via the software sequence: Enable Reset (66h) followed by Reset Device (99h), completing in ~30 µs.
What is the exact pin configuration for W25Q64JVDAIQ TR?
W25Q64JVDAIQ TR uses the 8-pin PDIP 300-mil (Package Code DA) with pinout: Pin 1 = /CS, Pin 2 = DO (IO1), Pin 3 = IO2, Pin 4 = GND, Pin 5 = DI (IO0), Pin 6 = CLK, Pin 7 = IO3, Pin 8 = VCC. This matches Figure 1e and Section 3.7 of the Winbond datasheet Revision C.
Can W25Q64JVDAIQ TR execute code directly from flash (XIP)?
Yes, W25Q64JVDAIQ TR supports true execute-in-place (XIP) via Fast Read Quad I/O (EBh) and Fast Read Quad Output (6Bh) instructions. With QE bit enabled and proper MCU SPI controller configuration, it delivers up to 532 MB/s effective throughput - sufficient for real-time code execution in Cortex-M4/M7 and RISC-V SoCs without intermediate RAM loading.
How many program/erase cycles does W25Q64JVDAIQ TR guarantee per sector?
W25Q64JVDAIQ TR guarantees a minimum of 100,000 program/erase cycles per sector, as specified in Section 2 (Features) and Table 9.6 of the datasheet. This endurance rating applies to all 2,048 uniform 4KB sectors and is validated across the full –40°C to +85°C operating range.
Is the 64-bit unique ID in W25Q64JVDAIQ TR factory-programmed and permanently readable?
Yes, W25Q64JVDAIQ TR includes a factory-programmed, unalterable 64-bit unique serial number accessible via the Read Unique ID Number instruction (4Bh). This ID is laser-trimmed during final test and remains readable throughout the device's lifetime, enabling secure device authentication and inventory tracking in production and field deployments.
