Product details
Overview
W25Q64JWTBIQ TR from Winbond is a 64M-bit (8MB) 1.8V serial NOR flash memory supporting Standard, Dual, and Quad SPI interfaces with up to 133MHz clock frequency, 66MB/s continuous read throughput, and industrial-grade -40°C to +105°C operation. It features uniform 4KB sectors, 32KB/64KB blocks, erase/program suspend/resume, and hardware write protection via /WP pin - deployed in embedded boot code storage, firmware update partitions, and XIP-capable microcontroller systems.
For engineers reviewing the W25Q64JWTBIQ TR datasheet, W25Q64JWTBIQ TR pinout, W25Q64JWTBIQ TR application, or W25Q64JWTBIQ TR equivalent, key selection criteria include Quad SPI enable (QE bit), /HOLD vs /RESET pin availability per package, 1.7–1.95V supply compliance, sector-level lock granularity, and JEDEC SFDP register support for auto-configuration.
Technical Context
The W25Q64JWTBIQ TR implements a SPI-compatible command set with three operational modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), where Quad mode requires non-volatile QE bit setting in Status Register-2. Its architecture includes a 256-byte page buffer, 2,048 erasable 4KB sectors, and dedicated security registers (3 × 256 bytes).
It supports hardware reset only on TFBGA and SOIC-16 packages - not on the WSON 8x6-mm (ZE) package used by W25Q64JWTBIQ TR - and uses /HOLD as IO3 in Quad mode. Write protection combines volatile/non-volatile status bits (BP2–BP0, TB, SEC, CMP) with dedicated /WP pin control and OTP-lockable security registers.
Key Specifications

Pinout & Package
W25Q64JWTBIQ TR uses the 8-pad WSON 8x6-mm package (Package Code ZE), with exposed thermal pad. Pin functions are identical across SOIC/WSON/XSON/USON variants except for /RESET pin absence - this variant does not include a dedicated /RESET pin.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; high-impedance DO/IOs when deasserted; required edge transition before instruction acceptance |
| DO (IO1) | Serial Data Output / Quad I/O 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad mode; falls on CLK edge |
| /WP (IO2) | Write Protect Input / Quad I/O 2 | Active-low hardware lock for status register; becomes IO2 when QE=1 in Quad mode |
| GND | Ground Reference | Primary return path for all I/O and core logic; must be low-impedance for timing integrity |
| DI (IO0) | Serial Data Input / Quad I/O 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad mode; rises on CLK edge |
| CLK | Serial Clock Input | Master-generated timing reference; supports Mode 0 and Mode 3; max 133 MHz in Quad I/O |
| /HOLD (IO3) | Hold Input / Quad I/O 3 | Pauses active transfers when low; becomes IO3 in Quad mode; not available as /HOLD when QE=1 |
| VCC | Power Supply | 1.7–1.95 V core supply; decoupling capacitor required near pin for stable read/write margins |
Key Features
| Feature | Design Value |
|---|---|
| Dual/Quad SPI Read Acceleration | Enables 66 MB/s continuous reads via Fast Read Quad I/O (EBh), reducing boot time by >4× vs Standard SPI |
| Erase/Program Suspend & Resume | Allows background execution of time-critical tasks while flash operations pause - critical for real-time OS integration |
| Uniform 4KB Sector Architecture | Permits independent locking and erasing of firmware configuration sections without affecting adjacent application code |
| Hardware + Software Write Protection | Combines /WP pin control with BP/TB/SEC/CMP bits to prevent accidental corruption during power transients or SW faults |
| JEDEC SFDP Register Support | Enables automatic driver initialization via standardized parameter table - eliminates hard-coded timing constants in BSPs |
| 64-bit Unique Serial Number | Provides device-level traceability for secure provisioning, anti-cloning, and field failure root-cause analysis |
Applications

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 | 3.3V supply, 104MHz max Quad SPI, no /HOLD pin in 8-pin SOIC, lacks SFDP register | Requires level-shifting in 1.8V systems; no auto-configuration support; lower temperature grade (–40°C to +85°C) | Select only if legacy 3.3V design constraints prohibit voltage translation and SFDP is unused. |
| S25FL164K0XMFI011 | 1.8V supply, 80MHz Quad SPI, 128KB sector minimum erase, no /WP pin in 8-pin WSON | Coarser erase granularity limits firmware partitioning flexibility; missing hardware write protect pin increases software dependency. | Prefer for cost-sensitive designs where 128KB erase alignment is acceptable and /WP is not required for safety-critical lock. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI011, the W25Q64JWTBIQ TR uniquely combines 1.8V operation, 133MHz Quad SPI, 4KB sector erase, integrated /WP pin, and SFDP - making it optimal for new industrial and automotive designs requiring both performance and configurability.

FAQ
What is the package type and footprint of W25Q64JWTBIQ TR?
W25Q64JWTBIQ TR uses the 8-pad WSON 8x6-mm package (JEDEC MO-255, Package Code ZE) with an exposed thermal pad. It shares pinout compatibility with other WSON variants (ZP, XG, UU) but differs from TFBGA and SOIC packages by omitting the dedicated /RESET pin. Footprint dimensions are 8.0 mm × 6.0 mm × 0.75 mm height, with 0.8 mm pad pitch.
Does W25Q64JWTBIQ TR support hardware reset (/RESET pin)?
No, W25Q64JWTBIQ TR does not support hardware reset. The /RESET pin is only available on SOIC-16 and TFBGA packages per Winbond documentation. This WSON 8x6-mm variant relies solely on software reset (66h + 99h instructions). Designers must implement robust power sequencing and software-initiated recovery instead of hardware assertion.
How is Quad SPI mode enabled on W25Q64JWTBIQ TR?
Quad SPI mode on W25Q64JWTBIQ TR is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 using the Write Status Register-2 (31h) instruction. Once QE=1, pins /WP and /HOLD become IO2 and IO3 respectively. The change persists across power cycles unless explicitly cleared, and is verified via Read Status Register-2 (35h).
What is the minimum supply voltage required for reliable operation of W25Q64JWTBIQ TR?
W25Q64JWTBIQ TR requires a minimum supply voltage of 1.7 V for guaranteed specification compliance across its full operating temperature range (–40°C to +105°C). Operation below 1.7 V may result in undefined behavior, failed writes, or incomplete erase cycles - especially during power-up sequences where internal regulators require stable VCC before accepting commands.
Can W25Q64JWTBIQ TR be used for Execute-in-Place (XIP) applications?
Yes, W25Q64JWTBIQ TR supports Execute-in-Place (XIP) via Dual and Quad SPI interfaces. Its 133 MHz Quad I/O clock and Fast Read Quad I/O (EBh) instruction deliver up to 66 MB/s sustained read throughput, enabling direct code execution from flash on compatible microcontrollers - eliminating need for RAM shadowing in resource-constrained embedded systems.
