Product details
Overview
W25Q64JVTBIQ from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with 133 MHz clock rate, 2.7–3.6 V supply, -40°C to +105°C industrial-plus temperature grade, and 4KB uniform sector architecture for code storage and data logging in embedded systems.
For engineers reviewing the W25Q64JVTBIQ datasheet, W25Q64JVTBIQ pinout, W25Q64JVTBIQ application, or W25Q64JVTBIQ equivalent, this page delivers verified pin functions, JEDEC-compliant ID support, Quad Enable (QE) configuration, erase/program suspend capability, and package-specific /RESET availability - all critical for boot code reliability, XIP execution, and secure firmware updates.
Technical Context
The W25Q64JVTBIQ implements a flexible SPI command set including Standard (DI/DO), Dual (IO0/IO1), and Quad (IO0–IO3) I/O modes, with QE bit in Status Register-2 enabling hardware-switched Quad operation. Its block diagram integrates a 256-byte page buffer, SFDP register for discoverable parameters, and three 256-byte security registers.
It supports full instruction-level compatibility with JEDEC JESD216, including Read JEDEC ID (9Fh), Read SFDP (5Ah), and 64-bit unique serial number (4Bh). Erase granularity includes 4KB sectors (2,048 total), 32KB blocks (1,024), and 64KB blocks (128), with program-erase endurance of ≥100K cycles per sector and >20-year data retention.

Pinout & Package
W25Q64JVTBIQ uses the 8-pin SOIC 208-mil package (Package Code SS), with pins arranged in standard dual-inline configuration and fully compatible with industry-standard PCB footprints for 208-mil SOIC.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | /CS | Chip Select input - active-low enable; high-impedance DO during deselect; required high-to-low transition before instruction acceptance |
| 2 | DO (IO1) | Data Output / Quad I/O1 - bidirectional in Dual/Quad mode; used for status/data read on CLK falling edge |
| 3 | /WP (IO2) | Write Protect input / Quad I/O2 - active-low hardware protection; becomes IO2 when QE=1 |
| 4 | GND | Ground reference - must be low-impedance connection to minimize noise coupling into SPI signals |
| 5 | DI (IO0) | Data Input / Quad I/O0 - bidirectional in Dual/Quad mode; used for instruction/address/data write on CLK rising edge |
| 6 | CLK | Serial Clock input - supports Mode 0 and Mode 3; timing-critical path requiring controlled trace length and impedance |
| 7 | /HOLD (IO3) | Hold input / Quad I/O3 - pauses ongoing operation when low; becomes IO3 in Quad mode (QE=1); not available as /RESET |
| 8 | VCC | Power supply - requires local 100 nF ceramic decoupling capacitor placed within 5 mm of pin |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI with Non-Volatile QE | Status Register-2 Quad Enable bit persists across power cycles - eliminates boot-time reconfiguration overhead |
| Erase/Program Suspend & Resume | Allows background erase or program to pause for higher-priority reads - essential for real-time interrupt handling in XIP systems |
| Hardware Write Protection | /WP pin + BP/SEC/TB bits enable sector-level lockdown without software intervention - prevents accidental firmware corruption |
| JEDEC-Compliant Unique ID | 64-bit factory-programmed serial number accessible via 4Bh instruction - enables device authentication and secure provisioning |
| Discoverable Parameters (SFDP) | Read-only SFDP register (5Ah) provides standardized, versioned memory map and timing data - simplifies automated toolchain integration |

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 |
|---|---|---|---|
| MX25L6433FZC-10G | 64 M-bit, 104 MHz max clock, no /RESET pin in 8-pin SOIC, lacks SFDP register | Supports Standard/Dual SPI only; no Quad I/O or suspend/resume commands | Choose for cost-sensitive designs where Quad bandwidth and advanced security are unnecessary |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max clock, 1.8 V core (3.3 V I/O), includes HyperBus interface option | Requires voltage translation for 3.3 V-only systems; HyperBus adds complexity vs. SPI simplicity | Prefer when migrating to Cypress/Infineon ecosystem or needing future HyperBus scalability |
Compared with MX25L6433FZC-10G and S25FL164K0XMFI010, W25Q64JVTBIQ delivers higher throughput (133 MHz vs. ≤104 MHz), built-in Quad I/O and suspend/resume, plus JEDEC SFDP and 64-bit UID - making it optimal for XIP, secure OTA, and industrial-plus thermal environments where feature completeness outweighs marginal BOM cost.

FAQ
What is the operating temperature range of the W25Q64JVTBIQ?
The W25Q64JVTBIQ is rated for -40°C to +105°C, qualifying it for industrial-plus applications such as motor drives, PLCs, and automotive infotainment head units. This extended range is confirmed in the device's ordering information table and electrical characteristics section, distinguishing it from commercial-grade variants limited to +85°C.
Does W25Q64JVTBIQ support Quad SPI mode, and how is it enabled?
Yes, W25Q64JVTBIQ supports Quad SPI via IO0–IO3 when the Quad Enable (QE) bit in Status Register-2 is set to '1'. This bit is non-volatile and retains its state across power cycles. Enabling QE converts /WP and /HOLD pins to IO2 and IO3 respectively - a hardware configuration change that must be performed once during initialization.
Is the /RESET pin available on the W25Q64JVTBIQ package?
No, the W25Q64JVTBIQ uses the 8-pin SOIC 208-mil (SS) package, which does not include a dedicated /RESET pin. Hardware reset is only available on SOIC-16 (SF) and TFBGA (TB/TC) packages. For W25Q64JVTBIQ, system-level reset must be handled via software reset sequence (66h followed by 99h).
What security features does W25Q64JVTBIQ provide beyond basic write protection?
W25Q64JVTBIQ includes three 256-byte one-time-programmable (OTP) security registers, a 64-bit unique serial number (readable via 4Bh), individual sector lock/unlock (36h/39h), and SFDP register compliance. These features enable cryptographic key storage, device identity binding, and secure firmware signing - extending protection far beyond /WP pin and status register BP bits.
Can W25Q64JVTBIQ be used for execute-in-place (XIP) applications?
Yes, W25Q64JVTBIQ is explicitly optimized for XIP use cases. Its 133 MHz Quad SPI clock support enables up to 532 MHz effective read bandwidth, and its uniform 4KB sector architecture allows atomic firmware updates without disrupting executing code. The datasheet confirms suitability for "executing code directly from Dual/Quad SPI (XIP)" in the General Descriptions section.
