Product details
Overview
W25Q64FVZPIF TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating at up to 104 MHz clock frequency with 50 MB/s continuous read throughput, 4KB uniform sector erase granularity, and single 2.7–3.6 V supply - deployed for code execution (XIP), firmware storage, and parameter retention in microcontroller-based embedded systems.
For engineers reviewing the W25Q64FVZPIF TR datasheet, W25Q64FVZPIF TR pinout, W25Q64FVZPIF TR application, or W25Q64FVZPIF TR equivalent, key selection considerations include Quad Enable (QE) bit configuration for IO2/IO3 remapping, /WP and /HOLD pin availability in standard vs. quad mode, 4KB sector flexibility for OTA updates, and JEDEC ID (EF4017h) validation during initialization.
Technical Context
The W25Q64FVZPIF TR implements a SPI-compatible command set with hardware- and software-based write protection, including top/bottom block protect (TB), sector/block protect bits (BP2–BP0), and status register lock (SRP0/SRP1). Its architecture supports erase/program suspend/resume for real-time interrupt handling during flash operations.
It features three 256-byte security registers with OTP locks, a 64-bit unique serial number, SFDP register for discoverable parameters, and QPI mode enabling 2-clock instruction cycles to reduce protocol overhead - all while maintaining full backward compatibility with legacy SPI controllers via mode switching.

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 | 64Mb, 104 MHz max, same SOIC-8 package; lacks QPI mode and SFDP register | No auto-configuration support; requires fixed timing setup in host driver | Preferred where QPI or SFDP is unused and cost sensitivity outweighs future-proofing |
| S25FL164K0XMFI010 | 64Mb, 80 MHz max, supports HyperBus but not QPI; includes ECC and configurable latency | Better error resilience for long-life deployments; higher latency in standard SPI mode | Chosen when system-level ECC coverage is mandated and QPI bandwidth is not required |
Compared with W25Q64FVZPIF TR, MX25L6433FZNI-10G offers identical pinout and basic SPI functionality at lower cost but omits QPI and SFDP - limiting configurability. S25FL164K0XMFI010 adds ECC and latency tuning but trades 24 MHz clock speed and lacks QPI acceleration, making it less suitable for XIP-critical designs.

FAQ
What interface protocols does the W25Q64FVZPIF TR support?
The W25Q64FVZPIF TR supports Standard SPI (4-wire), Dual SPI (2 I/O), Quad SPI (4 I/O), and Quad Peripheral Interface (QPI) with 2-clock opcodes. QPI mode requires issuing the Enable QPI (38h) command and setting the Quad Enable (QE) bit in Status Register-2. All modes share the same physical pins but differ in signal usage and timing - for example, /WP and /HOLD become IO2 and IO3 in Quad/QPI modes.
How is the W25Q64FVZPIF TR pinout configured in SOIC-8 package?
The W25Q64FVZPIF TR in SOIC-8 (package code SS) has pin 1 = /CS, pin 2 = DO (IO1), pin 3 = /WP (IO2), pin 4 = GND, pin 5 = DI (IO0), pin 6 = CLK, pin 7 = /HOLD (IO3), and pin 8 = VCC. This matches the 8-pin VSOP and PDIP variants. The /WP and /HOLD pins function as hardware write-protect and hold controls only when QE=0; they serve as IO2 and IO3 in Quad/QPI mode (QE=1).
Does the W25Q64FVZPIF TR support execute-in-place (XIP) operation?
Yes, the W25Q64FVZPIF TR supports true XIP via Continuous Read Mode and Quad SPI/QPI interfaces. With as few as 8 clocks to initiate address fetch and wrap lengths up to 64 bytes, it delivers deterministic latency for direct code execution from flash. Verified performance reaches 50 MB/s sustained read throughput using Fast Read Quad I/O (6Bh) or QPI instructions, outperforming many parallel flash alternatives in space-constrained designs.
What security features are implemented in the W25Q64FVZPIF TR?
The W25Q64FVZPIF TR includes hardware write-protection (/WP pin + TB/BP bits), volatile/non-volatile status register locks (SRP0/SRP1), three 256-byte OTP-lockable security registers, a factory-programmed 64-bit unique serial number, and JEDEC-standard SFDP register for parameter discovery. Security registers can store cryptographic keys or calibration data and are permanently locked via OTP fuses - preventing post-deployment modification or readout.
What is the endurance and data retention specification for the W25Q64FVZPIF TR?
The W25Q64FVZPIF TR guarantees ≥100,000 program/erase cycles per 4KB sector and ≥20 years of data retention at +25°C ambient temperature. Retention is derated per JEDEC JESD22-A117, with minimum 10-year retention validated at +85°C. Endurance applies uniformly across all sectors; no wear-leveling controller is integrated - system-level management is required for longevity-critical applications.
