Product details
Overview
W25Q64JWBYIQ TR from Winbond is a 1.8V, 64M-bit (8MB) serial NOR flash memory supporting Standard, Dual, and Quad SPI interfaces with up to 133MHz clock frequency, 66MB/s continuous read throughput, and 4KB uniform sector architecture - deployed for code execution (XIP), firmware storage, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q64JWBYIQ TR datasheet, W25Q64JWBYIQ TR pinout, W25Q64JWBYIQ TR application, or W25Q64JWBYIQ TR equivalent, this page delivers verified package mapping (8-pin USON 4x3-mm), confirmed Quad I/O timing behavior, JEDEC ID and SFDP register support, hardware write protection via /WP, and suspend/resume capability for real-time system interrupt handling.
Technical Context
The W25Q64JWBYIQ TR implements a quad I/O SPI interface requiring the non-volatile Quad Enable (QE) bit in Status Register-2 to be set; when enabled, /WP becomes IO2 and /HOLD becomes IO3. It supports SPI modes 0 and 3, with dual/quad instructions enabling 2×–6× faster data transfer versus standard SPI.
Its architecture includes 32,768 programmable pages (256 bytes each), 2,048 erasable 4KB sectors, and 128 erasable 64KB blocks. Erase/program suspend & resume functions allow background operations to be paused for higher-priority tasks without data loss.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 M-bit (8 MB) - supports full firmware images for mid-tier microcontrollers without external memory expansion. |
| Supply Voltage | 1.7 V to 1.95 V - compatible with modern low-voltage SoCs and battery-powered designs; eliminates level-shifting requirements. |
| Max Clock Frequency | 133 MHz Quad I/O - enables 532 MB/s theoretical bandwidth (133 MHz × 4 lines), critical for fast XIP boot and OTA update streaming. |
| Erase Granularity | Uniform 4 KB sectors - allows fine-grained firmware partitioning (e.g., bootloader + app + config) with independent update capability. |
| Endurance & Retention | 100,000 program-erase cycles / 20+ years data retention - validated for industrial lifecycle requirements in automotive ECUs and medical devices. |
| Security Features | 64-bit unique ID, three 256-byte security registers, OTP lock bits, and SFDP register - enables secure device authentication and encrypted firmware binding. |
| Operating Temperature | −40°C to +85°C - qualified for extended industrial environments including motor control, smart meters, and edge gateways. |
Pinout & Package
W25Q64JWBYIQ TR is supplied in an 8-pad USON 4x3-mm package (package code UU), with wettable flank side walls for automated optical inspection (AOI) and enhanced solder joint reliability in high-volume SMT assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable signal; must transition high→low before instruction acceptance; controls device power state (standby vs active). |
| DO (IO1) | Data Output / Quad I/O Line 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad mode; used for read data and status feedback. |
| /WP (IO2) | Write Protect Input / Quad I/O Line 2 | Hardware-level protection for status register and memory array; active-low; repurposed as IO2 when QE=1. |
| GND | Ground Reference | Primary return path for all I/O and core logic; requires low-impedance PCB connection to minimize noise coupling during high-speed reads. |
| DI (IO0) | Data Input / Quad I/O Line 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad mode; carries instructions, addresses, and program data. |
| CLK | Serial Clock Input | Synchronizes all SPI transfers; supports modes 0 and 3; timing-critical for achieving 133 MHz Quad I/O operation. |
| /HOLD (IO3) | Hold Input / Quad I/O Line 3 | Pauses ongoing transfers while /CS remains asserted; disabled in Quad mode (repurposed as IO3); active-low with internal pull-up. |
| VCC | Power Supply | 1.7–1.95 V supply; internal voltage regulation ensures stable core operation across voltage tolerance and temperature range. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O Read Performance | 66 MB/s continuous transfer rate - reduces boot time by >4× vs standard SPI, enabling sub-100ms firmware load in resource-limited MCUs. |
| Erase/Program Suspend & Resume | Allows interruption of long erase (up to 100 ms) or program (up to 1.2 ms) operations to service real-time interrupts without corruption. |
| Hardware Write Protection | /WP pin + BP/SEC/TB bits provide layered protection - prevents accidental overwrite of bootloader or calibration data during field updates. |
| JEDEC ID & SFDP Support | Enables automatic driver detection and configuration in Linux/RTOS environments; eliminates hardcoded timing parameters in BSPs. |
| Unique 64-bit Serial Number | Factory-programmed per-device ID - used for secure provisioning, anti-cloning, and traceability in certified production workflows. |

FAQ
What is the operating voltage range for the W25Q64JWBYIQ TR?
The W25Q64JWBYIQ TR operates from 1.7 V to 1.95 V. This narrow 1.8V nominal range ensures compatibility with modern ultra-low-power microcontrollers and eliminates the need for external voltage translation. Operation outside this range may cause undefined behavior or permanent damage. The W25Q64JWBYIQ TR includes built-in power-on reset circuitry that holds the device in reset until VCC stabilizes within specification.
Does the W25Q64JWBYIQ TR support Quad SPI mode out of the box?
No - the W25Q64JWBYIQ TR requires the Quad Enable (QE) bit in Status Register-2 to be set before Quad SPI operation is activated. By default, QE = 0 after power-up or reset, limiting interface to Standard or Dual SPI. Setting QE = 1 reassigns /WP and /HOLD pins to IO2 and IO3, enabling full Quad I/O functionality. This configuration is non-volatile unless explicitly cleared.
What package type does the W25Q64JWBYIQ TR use, and is it AOI-compatible?
The W25Q64JWBYIQ TR uses an 8-pad USON 4x3-mm package (package code UU) with wettable flank side walls. This geometry supports automated optical inspection (AOI) of solder joints during SMT assembly and improves reflow yield in high-volume manufacturing. Unlike traditional SOIC or WSON, the USON footprint minimizes board area while maintaining mechanical robustness for vibration-prone applications.
How does hardware write protection work on the W25Q64JWBYIQ TR?
Hardware write protection on the W25Q64JWBYIQ TR is implemented via the active-low /WP pin, which - when held low - prevents writes to the status register and memory array, regardless of software commands. Its effect is combined with volatile/non-volatile block protect (BP) bits and top/bottom (TB) flags to create hierarchical protection zones. The /WP pin remains functional even when Quad SPI is enabled, though its pin function changes to IO2.
Can the W25Q64JWBYIQ TR be used for execute-in-place (XIP) applications?
Yes - the W25Q64JWBYIQ TR supports true XIP operation via Dual and Quad SPI interfaces, with verified 133MHz clock rates enabling deterministic instruction fetch latency. Its uniform 4KB sector architecture allows precise mapping of executable code segments into MCU address space, and erase/program suspend/resume ensures real-time task preemption without corrupting active code regions. XIP performance is validated across −40°C to +85°C.
