Product details
Overview
W25Q64FWZPIQ TR from Winbond is a 1.8V, 64M-bit (8MB) serial NOR flash memory supporting Standard/Dual/Quad SPI and QPI interfaces. It delivers 104MHz clock rate (416MHz equivalent Quad I/O), 4KB uniform sector erase, 256-byte page programming, and true execute-in-place (XIP) capability for embedded code storage in space-constrained microcontroller systems.
For engineers reviewing the W25Q64FWZPIQ TR datasheet, W25Q64FWZPIQ TR pinout, W25Q64FWZPIQ TR application, or W25Q64FWZPIQ TR equivalent, this device is selected for low-voltage boot code storage, firmware update partitioning, and secure parameter retention in industrial controllers, IoT edge nodes, and automotive body electronics where 1.65–1.95V supply, -40°C to +85°C operation, and JEDEC-compliant ID support are required.
Technical Context
The W25Q64FWZPIQ TR implements a flexible SPI command architecture with volatile/non-volatile status register control (BP2–BP0, TB, SEC, QE, SRP0/SRP1), enabling hardware- and software-based memory protection down to 4KB sectors. Its dual-function pins (/WP and /HOLD become IO2/IO3 when QE=1) support mode-switching between Standard/Dual/Quad SPI and QPI without external logic.
It integrates three 256-byte one-time-programmable (OTP) security registers, 64-bit unique ID, SFDP register for discoverable parameters, and erase/program suspend/resume functionality - all operating within 4mA active and <1µA power-down current at 1.8V.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash memory applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L6433FZNI-10G | 64M-bit, 3V supply (2.7–3.6V); no QPI mode; 80MHz max clock; lacks security registers and unique ID | Requires level-shifting for 1.8V systems; unsuitable for secure key storage or XIP-critical latency paths | Select only if existing 3V design reuse is mandatory and security/XIP features are unused. |
| S25FL164K0XMFI010 | 64M-bit, 1.7–2.0V supply; supports Octal DDR but no QPI; includes HyperBus interface; higher pin count (16-pin SOIC) | Needs PCB redesign for 16-pin footprint; offers higher bandwidth but over-spec for most MCU-based XIP use cases | Prefer when migrating to HyperBus-capable SoCs; avoid for drop-in replacement in 8-pin WSON layouts. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64FWZPIQ TR uniquely balances 1.8V compatibility, QPI acceleration, integrated security primitives, and 8-pin WSON packaging - making it optimal for cost-sensitive, space-constrained, and security-aware embedded designs without requiring interface or voltage translation.

FAQ
What is the operating voltage range for the W25Q64FWZPIQ TR?
The W25Q64FWZPIQ TR operates from 1.65V to 1.95V. This strict 1.8V nominal range eliminates need for level shifters when interfacing with modern 1.8V microcontrollers and FPGAs. Operation outside this window risks data corruption or failure to execute commands; the device does not support 3.3V or dual-voltage operation. All electrical characteristics - including timing, current draw, and endurance - are specified and guaranteed only within this range.
Does the W25Q64FWZPIQ TR support execute-in-place (XIP) functionality?
Yes, the W25Q64FWZPIQ TR supports true XIP via Continuous Read Mode and Quad SPI/QPI interfaces. With as few as 8 clocks to initiate a read and up to 416MHz equivalent throughput, it enables direct code execution from flash without copying to RAM. The 4KB uniform sector architecture further supports safe in-field updates by allowing partial image replacement while preserving running code segments.
How is hardware write protection implemented on the W25Q64FWZPIQ TR?
Hardware write protection on the W25Q64FWZPIQ TR combines the /WP pin with non-volatile status register bits (BP2–BP0, TB, SEC). When /WP is held low and BP bits are set, writes to protected sectors - down to 4KB granularity - are blocked regardless of software commands. This dual-layer scheme prevents accidental or malicious firmware overwrite during power transients or software faults, and remains active even after reset or power cycle.
What package type does the W25Q64FWZPIQ TR use, and is it lead-free?
The W25Q64FWZPIQ TR uses an 8-pin WSON 6×5-mm package (JEDEC MO-252, Package Code ZP) with exposed thermal pad and matte tin (Sn) finish. It is RoHS-compliant and lead-free per EU Directive 2011/65/EU. The package supports standard reflow profiles (J-STD-020D) and provides superior thermal performance versus SOIC, making it ideal for compact, thermally demanding applications.
Can the W25Q64FWZPIQ TR be used in automotive applications?
Yes, the W25Q64FWZPIQ TR is rated for -40°C to +85°C operation and qualified to AEC-Q100 stress test standards for automotive-grade reliability. Its 20-year data retention, 100,000 program/erase cycles, and hardware write protection make it suitable for body control modules, infotainment boot storage, and ADAS sensor firmware - provided system-level ESD and EMC requirements are met per ISO 11452 and ISO 7637.
