Product details
Overview
W25Q64JVZEIQ from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces. It operates from 2.7V to 3.6V, delivers up to 133MHz clock frequency (532MHz equivalent Quad I/O), features uniform 4KB sectors (2,048 total), and supports XIP (execute-in-place) for code storage in embedded microcontrollers.
For engineers reviewing the W25Q64JVZEIQ datasheet, W25Q64JVZEIQ pinout, W25Q64JVZEIQ application, or W25Q64JVZEIQ equivalent, this device is selected for firmware storage, boot code execution, and parameter logging where space-constrained PCBs require high-speed serial memory with hardware write protection and JEDEC-compliant identification.
Technical Context
The W25Q64JVZEIQ implements a quad-capable SPI interface with configurable I/O modes: Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3), enabled via non-volatile QE bit in Status Register-2. Its architecture includes a 256-byte page buffer, sector/block erase hierarchy (4KB/32KB/64KB), and erase/program suspend-resume capability.
It integrates three 256-byte security registers, 64-bit unique ID, SFDP register for discoverable parameters, and dual write-protection mechanisms-software-controlled status bits (BPx, TB, SEC) and hardware pins (/WP, /HOLD). The /RESET pin is dedicated and functional only in TFBGA and SOIC-16 packages; W25Q64JVZEIQ uses WSON 8x6-mm (ZE), so /HOLD serves as IO3 in Quad mode and no dedicated /RESET is present.

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 | 64 M-bit, 104 MHz max clock, no Quad Enable bit in Status Register-2; uses different SFDP layout | Lacks native Quad I/O mode; requires software-managed bit-banging for 4-line reads - lower throughput | Select only if legacy driver stack lacks QE bit support and 133 MHz timing is not required. |
| S25FL064L0XMFI001 | 64 M-bit, 80 MHz max clock, supports Octal DTR mode; includes built-in ECC and sector lockdown | Higher reliability features but larger footprint (16-pin SOIC); no WSON 8x6-mm option available | Prefer for automotive ASIL-B designs needing ECC; avoid when board space or Quad SPI speed is critical. |
Compared with MX25L6433FZNI-10G and S25FL064L0XMFI001, W25Q64JVZEIQ delivers the highest Quad SPI bandwidth in a compact WSON package, supports seamless XIP with JEDEC SFDP auto-configuration, and provides granular 4KB sector protection - making it optimal for cost-sensitive, space-constrained industrial controllers requiring fast firmware access.

FAQ
What is the package type and lead finish of W25Q64JVZEIQ?
W25Q64JVZEIQ uses an 8-pad WSON 8×6-mm package (JEDEC MO-241AC, code ZE) with matte tin (Sn) lead finish. It features wettable flanks for solder joint inspection and complies with RoHS and REACH standards. This package supports reflow soldering per J-STD-020 and is optimized for high-density PCB layouts.
Does W25Q64JVZEIQ include a hardware reset pin (/RESET)?
No, W25Q64JVZEIQ does not include a dedicated /RESET pin. The /RESET function is only available on SOIC-16 (SF) and TFBGA (TB/TC) packages. In W25Q64JVZEIQ's WSON ZE package, pin 7 is /HOLD (which becomes IO3 in Quad mode), and hardware reset must be implemented via software sequence (66h + 99h) or system-level power cycling.
How is Quad SPI mode enabled on W25Q64JVZEIQ?
Quad SPI mode on W25Q64JVZEIQ is enabled by setting the Quad Enable (QE) bit in Status Register-2 (SR2) to '1' using Write Status Register-2 (31h) instruction. Once set, /WP (pin 3) and /HOLD (pin 7) become IO2 and IO3 respectively. QE is non-volatile, persisting across power cycles unless explicitly cleared.
What erase block sizes does W25Q64JVZEIQ support?
W25Q64JVZEIQ supports four erase granularities: 4 KB sectors (2,048 total), 32 KB blocks (1,024 blocks), 64 KB blocks (512 blocks), and full chip erase. All erase operations are uniform - no partial or variable-size sectors - enabling deterministic wear leveling and predictable timing in firmware update routines.
Can W25Q64JVZEIQ be used for execute-in-place (XIP) applications?
Yes, W25Q64JVZEIQ supports execute-in-place (XIP) directly from Quad SPI interface using Fast Read Quad I/O (EBh) instruction. With 133 MHz clock and 4-line data transfer, it delivers up to 532 MB/s effective bandwidth - sufficient for real-time code execution in Cortex-M7/M33 and RISC-V cores without local RAM buffering.
