Product details
Overview
W25Q64JWZPIQ from Winbond is a 1.7V–1.95V, 64M-bit (8MB) serial NOR flash memory with Dual/Quad SPI interface, organized into 32,768 × 256-byte pages and supporting 4KB/32KB/64KB erase granularity. It delivers up to 133MHz Quad I/O clocking (532MB/s equivalent bandwidth), <1µA power-down current, and operates across –40°C to +85°C - deployed in boot code storage and XIP firmware execution for microcontrollers in space-constrained IoT edge nodes.
For engineers reviewing the W25Q64JWZPIQ datasheet, W25Q64JWZPIQ pinout, W25Q64JWZPIQ application, or W25Q64JWZPIQ equivalent, this page provides verified pin functions, JEDEC-compliant ID support, SFDP register access, 64-bit unique serial number, and hardware write-protect (/WP) and hold (/HOLD) signal behavior specific to the ZPIQ (8-pad WSON 6×5-mm) package.
Technical Context
The W25Q64JWZPIQ implements a standard SPI bus (Mode 0/3) with optional Dual/Quad I/O operation enabled via non-volatile QE bit in Status Register-2. Its command set includes Fast Read Quad I/O (EBh), Quad Input Page Program (32h), and Erase/Program Suspend (75h/7Ah), enabling deterministic latency control during concurrent firmware updates and real-time data logging.
Internal architecture features a 256-byte page buffer, uniform 4KB sector layout (2,048 sectors), and three 256-byte security registers with OTP lock capability. Hardware reset (/RESET) is not available on the ZPIQ package; /HOLD pin doubles as IO3 in Quad mode, disabling hold functionality when QE=1.
Key Specifications

Pinout & Package
W25Q64JWZPIQ uses an 8-pad WSON 6×5-mm package (JEDEC MO-252, package code ZP), with exposed thermal pad. Pin 1 is marked by dot; pins are arranged counterclockwise from top-left corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; must transition high→low before instruction acceptance; high-impedance DO during deselect. |
| 2 DO (IO1) | Data Output / Quad I/O 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes; used for read data and status. |
| 3 /WP (IO2) | Write Protect Input / Quad I/O 2 | Hardware write lock for status register; becomes IO2 when QE=1; active-low, requires external pull-up if unused. |
| 4 GND | Ground Reference | Primary return path for all I/O and core logic; connects to thermal pad for thermal dissipation. |
| 5 DI (IO0) | Data Input / Quad I/O 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes; carries instructions, addresses, and write data. |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1). |
| 7 /HOLD (IO3) | Hold Input / Quad I/O 3 | Pauses ongoing transfers when low (active-low); disabled and repurposed as IO3 in Quad mode (QE=1). |
| 8 VCC | Power Supply | 1.7–1.95 V supply; decoupling capacitor (100 nF) required within 5 mm of pin for stable operation. |
Key Features
| Feature | Design Value |
|---|---|
| Dual/Quad SPI Interface | Enables scalable bandwidth: 2× (Dual) or 4× (Quad) over standard SPI - reduces firmware load time and supports XIP without external RAM buffering. |
| Erase/Program Suspend | Allows interruption of long erase/program cycles to service high-priority reads - essential for real-time systems requiring deterministic response. |
| Hardware Write Protection | /WP pin + status register BP bits provide layered protection against accidental writes - critical for bootloader and calibration data integrity. |
| JEDEC Compliance | Supports Manufacturer/Device ID (90h/9Fh), Unique ID (4Bh), and SFDP (5Ah) - ensures interoperability with standardized flash programming tools and OS drivers. |
| Security Registers | Three 256-byte OTP-capable registers store cryptographic keys or device-specific secrets - isolated from main array and lockable per sector. |
Applications
| Secure Boot Storage | Firmware Over-the-Air (OTA) |
|---|---|
Use Scenario: Storing signed bootloader images and public key certificates in immutable sectors. IC Role / Device Role / Timing Role: Primary non-volatile code storage with hardware write-protection and unique ID binding. Use Value: Prevents unauthorized firmware injection using /WP pin + BP bits and 64-bit UID for certificate chain binding. | Use Scenario: Receiving and validating delta firmware updates in battery-powered gateways. IC Role / Device Role / Timing Role: Dual-bank update storage with suspend/resume for atomic swap during live operation.

IC Role / Device Role / Timing Role: Parameter + data storage with 4KB sector granularity and 100K-cycle endurance. Use Value: Uniform 4KB sectors allow independent erasure of oldest log segment without corrupting configuration or calibration data. |
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 | 3.3V supply (vs. 1.8V); same 64M-bit density, Quad SPI, 133MHz max clock; no /HOLD pin in 8-pin SOIC variant. | Requires level-shifting in 1.8V systems; lacks /HOLD for multi-device arbitration; identical SFDP and security register support. | Select when legacy 3.3V infrastructure exists and power efficiency is secondary to toolchain compatibility. |
| S25FL164K0XMFI011 | 1.8V supply; 64M-bit; supports Octal DTR mode (up to 200MHz); different status register map and QE bit location. | Higher bandwidth potential but requires Cypress-compatible controller; no 64-bit UID; security registers limited to 128 bytes. | Choose for future-proofing with Octal-ready host controllers where sustained >500MB/s throughput justifies firmware rework. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI011, the W25Q64JWZPIQ uniquely combines 1.8V ultra-low-power operation (<1µA), integrated /HOLD for SPI bus sharing, and factory-programmed 64-bit UID - making it optimal for compact, battery-aware, and security-critical edge nodes.

FAQ
What is the operating voltage range for the W25Q64JWZPIQ?
The W25Q64JWZPIQ operates from 1.7 V to 1.95 V, optimized for 1.8 V system rails. This narrow range eliminates need for external voltage regulation in modern low-power MCUs and SoCs. Operation outside this window risks data corruption or failure to execute commands. The W25Q64JWZPIQ includes internal voltage monitoring that forces reset if VCC drops below threshold during write/erase cycles.
Does the W25Q64JWZPIQ support hardware reset via /RESET pin?
No, the W25Q64JWZPIQ does not include a dedicated /RESET pin. That function is only available on TFBGA and SOIC-16 packages (e.g., W25Q64JWxxTB or W25Q64JWxxSS variants). The ZPIQ package uses 8-pad WSON 6×5-mm and relies solely on software reset (66h + 99h instructions). System-level reset must be handled externally or via SPI command sequence.
How is Quad SPI mode enabled on the W25Q64JWZPIQ?
Quad SPI mode is enabled by setting the Quad Enable (QE) bit in Status Register-2 (SR2) to '1' using the Write Status Register-2 (31h) instruction. Once QE=1, pins /WP and /HOLD become IO2 and IO3 respectively. The W25Q64JWZPIQ retains QE state across power cycles unless cleared - ensuring persistent Quad mode without reconfiguration at boot.
What package type does the W25Q64JWZPIQ use, and what are its thermal characteristics?
The W25Q64JWZPIQ uses an 8-pad WSON 6×5-mm package (JEDEC MO-252, code ZP) with exposed thermal pad. Its θJA is 120°C/W (typ.) under standard JEDEC PCB conditions. For continuous 133MHz operation, a 25 mm² copper pour under the thermal pad and two 100-nF ceramic decoupling capacitors near VCC/GND are recommended to maintain junction temperature below 105°C.
Can the W25Q64JWZPIQ be used for secure key storage?
Yes, the W25Q64JWZPIQ includes three 256-byte security registers with One-Time-Programmable (OTP) lock capability, accessible via dedicated instructions (42h/44h/48h). These registers are electrically isolated from main memory and can be permanently locked after programming. Combined with the factory-programmed 64-bit unique ID, they support secure key binding and anti-cloning in certified bootloader implementations.
