Product details
Overview
W25Q64JWXGIQ TR from Winbond is a 1.8V, 64M-bit (8MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 133MHz clock frequency, 66MB/s continuous read throughput, and uniform 4KB sector erase architecture - deployed for code execution (XIP), firmware storage, and parameter retention in space-constrained embedded systems.
For engineers reviewing the W25Q64JWXGIQ TR datasheet, W25Q64JWXGIQ TR pinout, W25Q64JWXGIQ TR application, or W25Q64JWXGIQ TR equivalent, this page delivers verified electrical specs, package mapping to WSON 8x6-mm (ZE), validated Quad I/O timing behavior, JEDEC ID compliance, and real-world XIP and firmware update use cases - all grounded in Winbond's official Revision B datasheet.
Technical Context
The W25Q64JWXGIQ TR implements a quad I/O SPI interface requiring non-volatile QE bit (Status Register-2, bit 1) to be set for IO0–IO3 operation; /WP and /HOLD pins revert to IO2 and IO3 respectively in Quad mode. It supports SPI modes 0 and 3, with hardware reset available only on TFBGA/SOIC-16 packages - not on the WSON 8x6-mm (ZE) variant of this part.
Its memory array comprises 32,768 pages of 256 bytes each, organized into 2,048 erasable 4KB sectors and 128 erasable 64KB blocks. Erase/program suspend/resume functionality enables concurrent background operations, while SFDP (Serial Flash Discoverable Parameters) register enables host auto-configuration of timing and command sets.
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-power SoCs and battery-backed systems; no level-shifting required. |
| Max Clock Frequency | 133 MHz Quad I/O - enables 532 MB/s theoretical bandwidth (133 MHz × 4 lines), delivering 66 MB/s sustained read performance. |
| Erase Granularity | Uniform 4 KB sectors - allows fine-grained firmware partitioning (e.g., bootloader + app + config) without over-erasing. |
| Endurance & Retention | 100,000 program/erase cycles; >20 years data retention - suitable for field-updatable industrial firmware with infrequent writes. |
| Security Features | 64-bit unique ID, three 256-byte security registers, OTP-lockable sectors, and SFDP register - enables secure boot key binding and anti-cloning. |
| Operating Temperature | −40°C to +85°C - qualified for industrial-grade deployment in automotive ECUs, PLCs, and edge gateways. |
Pinout & Package
W25Q64JWXGIQ TR is packaged in an 8-pad WSON 8×6-mm (Package Code ZE), with exposed thermal pad. Pin functions are identical to other WSON variants per datasheet Section 3.2–3.3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; high-impedance DO/IO pins when deasserted; required to transition high→low before instruction acceptance. |
| DO (IO1) | Data Output / Bidirectional I/O1 | Unidirectional output in Standard SPI; bidirectional in Dual/Quad modes; used for status/data reads on falling CLK edge. |
| /WP (IO2) | Write Protect Input / Bidirectional I/O2 | Hardware write lock for status register; becomes IO2 in Quad mode when QE=1; active-low protection signal. |
| GND | Ground Reference | Primary return path for all I/O and core logic; must be low-impedance connection to minimize noise coupling during fast reads. |
| DI (IO0) | Data Input / Bidirectional I/O0 | Unidirectional input in Standard SPI; bidirectional in Dual/Quad modes; carries instructions/addresses on rising CLK edge. |
| CLK | Serial Clock Input | Master-generated timing reference; supports SPI modes 0 and 3; max 133 MHz for Quad I/O; requires clean edge integrity. |
| /HOLD (IO3) | Hold Input / Bidirectional I/O3 | Pauses ongoing SPI transfer when low; becomes IO3 in Quad mode when QE=1; not available as /HOLD in Quad operation. |
| VCC | Power Supply | 1.7–1.95 V core supply; internal LDO regulates internal logic; decoupling capacitor (≥1 µF) required near VCC/GND pins. |
Key Features
| Feature | Design Value |
|---|---|
| Quad I/O Read (EBh) | Enables 4-line bidirectional transfers at 133 MHz, achieving 66 MB/s sustained throughput - critical for fast XIP startup and OTA firmware streaming. |
| Erase/Program Suspend | Allows pausing a long erase or program operation to service urgent reads, then resuming - essential for real-time systems with mixed latency demands. |
| JEDEC ID & SFDP | Returns standardized manufacturer/device ID (9Fh) and SFDP register (5Ah) - enables automatic driver initialization and timing configuration in Linux/Bare-Metal bootloaders. |
| Individual Sector Lock | Per-sector (4KB) software/hardware lock via 32-bit security register - prevents unauthorized modification of bootloader or calibration data without full chip erase. |
| Low-Power Power-Down | 1 µA typical standby current - extends battery life in always-on IoT nodes and enables rapid wake-on-CS without voltage rail sequencing delays. |

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, 1.65–2.0V supply, 104MHz max Quad SPI, no /RESET pin in 8-pin SOIC/WSON | Lacks hardware reset and SFDP register; JEDEC ID differs - requires driver revalidation | Choose for cost-sensitive designs where SFDP auto-config and reset pin are unnecessary. |
| S25FL164K0XMFI010 | 64Mb, 2.7–3.6V supply, 80MHz Quad SPI, integrated ECC, 100K cycles, 20-year retention | Higher voltage range incompatible with 1.8V systems; includes on-die ECC but no security registers | Select only if migrating from 3.3V platforms and ECC for bit-flip mitigation is prioritized over security features. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64JWXGIQ TR uniquely combines 1.8V operation, SFDP support, 64-bit UID, and three security registers - making it optimal for secure, low-voltage, auto-configurable firmware storage where cryptographic binding and power efficiency are mandatory.

FAQ
What is the package type and footprint compatibility of the W25Q64JWXGIQ TR?
The W25Q64JWXGIQ TR uses an 8-pad WSON 8×6-mm package (JEDEC MO-241AC, Winbond code ZE) with exposed thermal pad. It shares pinout and footprint with other WSON variants (ZP, XG, UU) in the W25Q64JW family, enabling layout reuse across voltage or density variants - but requires verification of thermal pad soldering and clearance per IPC-7351B.
Does the W25Q64JWXGIQ TR support hardware reset (/RESET pin)?
No - the W25Q64JWXGIQ TR does not include a dedicated /RESET pin. Hardware reset is only available on SOIC-16 and TFBGA-24 packages per datasheet Section 4.6 and Note 1. This part relies solely on software reset (66h + 99h instructions) for recovery, which requires functional SPI communication.
How is Quad SPI mode enabled on the W25Q64JWXGIQ TR?
Quad SPI mode is enabled by setting the non-volatile Quad Enable (QE) bit (bit 1 of Status Register-2) via Write Status Register-2 (31h) instruction. Once set, /WP and /HOLD pins become IO2 and IO3 respectively, allowing 4-line bidirectional transfers using instructions like Fast Read Quad I/O (EBh).
What security mechanisms does the W25Q64JWXGIQ TR provide for firmware protection?
The W25Q64JWXGIQ TR provides hardware /WP pin locking, volatile/non-volatile block protect bits (BP2–BP0, TB, SEC), individual sector lock/unlock (36h/39h), OTP-programmable security registers, and a 64-bit unique ID. These enable layered protection: hardware lock for status register, software-defined sector lockdown, and cryptographic binding of firmware to device identity.
Is the W25Q64JWXGIQ TR compatible with SPI mode 3 (CPOL=1, CPHA=1)?
Yes - the W25Q64JWXGIQ TR explicitly supports both SPI mode 0 (CPOL=0, CPHA=0) and mode 3 (CPOL=1, CPHA=1) as stated in Section 6.1 of the datasheet. Mode selection is determined by the host controller; no device configuration is required, and CLK idle state must match the selected mode during /CS transitions.
