Product details
Overview
W25Q64CVZPJG TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting standard, dual, and quad SPI interfaces with up to 80 MHz clock frequency, 4KB uniform sector architecture, and hardware write protection via /WP and /HOLD pins - deployed in embedded boot code storage, firmware update partitions, and XIP-capable microcontroller systems.
For engineers reviewing the W25Q64CVZPJG TR datasheet, W25Q64CVZPJG TR pinout, W25Q64CVZPJG TR application, or W25Q64CVZPJG TR equivalent, key selection criteria include quad I/O enable (QE bit), 4mA active current draw, 1µA power-down current, JEDEC ID read capability (9Fh), and compatibility with continuous read mode for execute-in-place (XIP) operation.
Technical Context
The W25Q64CVZPJG 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. It supports erase granularity of 4KB sectors, 32KB blocks, and 64KB blocks, with up to 100,000 program/erase cycles and 20-year data retention.
Its internal architecture includes a 256-byte page buffer, SFDP register for discoverable parameters, three 256-byte security registers with OTP locks, and status register bits (BP0–BP2, TB, SEC, CMP, SRP0/SRP1) enabling flexible hardware/software write protection across top/bottom array regions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 M-bit (8 MB); enables full firmware image storage for mid-tier MCUs without external parallel bus. |
| Interface Support | Standard/Dual/Quad SPI; allows scalable bandwidth from 80 MHz single-line to 320 MHz effective quad-I/O throughput. |
| Erase Granularity | 4 KB sectors (2,048 total); permits fine-grained parameter updates without disturbing adjacent firmware sections. |
| Write Cycle Endurance | 100,000 program/erase cycles (industrial temp); supports frequent OTA firmware patching over product lifetime. |
| Data Retention | 20 years at +85°C; ensures long-term reliability in automotive and industrial control applications. |
| Power Supply | 2.7 V to 3.6 V single supply; compatible with 3.3 V logic domains without level-shifting circuitry. |
| Active Current | 4 mA typical at 80 MHz; minimizes system-level power budget impact during boot or firmware load. |
| Power-down Current | 1 µA typical; enables ultra-low-power sleep states in battery-backed or energy-harvested devices. |
Pinout & Package
W25Q64CVZPJG TR uses an 8-pin WSON 8x6-mm package (JEDEC MO-241AC, package code ZE), with exposed pad for thermal dissipation and space-constrained PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable signal; high-impedance DO/IO outputs when deasserted, reducing bus contention. |
| 2 DO (IO1) | Data Output / Quad I/O Line 1 | Unidirectional output in standard SPI; bidirectional I/O in dual/quad mode for high-speed read/write. |
| 3 /WP (IO2) | Write Protect Input / Quad I/O Line 2 | Hardware lock for status register when QE=0; repurposed as IO2 in quad mode (QE=1). |
| 4 GND | Ground Reference | Common return path for all I/O and core logic; must be low-inductance for stable SPI timing. |
| 5 DI (IO0) | Data Input / Quad I/O Line 0 | Unidirectional input in standard SPI; bidirectional I/O in dual/quad mode for address/instruction/data transfer. |
| 6 CLK | Serial Clock Input | Synchronous timing reference; supports Mode 0 and Mode 3 SPI; max 80 MHz for reliable setup/hold margins. |
| 7 /HOLD (IO3) | Hold Input / Quad I/O Line 3 | Pauses ongoing SPI transaction when asserted low (standard/dual only); becomes IO3 in quad mode. |
| 8 VCC | Power Supply | 2.7–3.6 V core and I/O supply; decoupling capacitor required within 5 mm of pin per layout guidelines. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Enable (QE) Bit | Non-volatile Status Register-2 bit enabling IO2/IO3 functionality; required before quad SPI instructions execute. |
| Continuous Read Mode | As few as 8 clocks to initiate read after instruction; eliminates per-byte overhead for true XIP execution. |
| Security Registers | Three 256-byte OTP-lockable registers for keys, calibration data, or secure boot assets - isolated from main array. |
| SFDP Register | JESD216-compliant flash parameter table; enables automatic driver configuration without hard-coded timing values. |
| Erase/Program Suspend | 75h/7Ah commands pause/resume background operations; allows time-critical interrupt service without data loss. |
| Unique 64-bit ID | Factory-programmed serial number per device; supports secure provisioning and anti-cloning in production. |

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, 2.7–3.6 V, same 8-pin WSON 8x6-mm (ZE) footprint. | Supports DTR (double-transfer-rate) mode; higher max frequency but no SFDP register or security registers. | Preferred when maximum read speed is critical and security features are not required. |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max clock, 2.7–3.6 V, 8-pin SOIC 208-mil (SS) package - not pin-compatible with ZE. | Includes HyperBus interface option; deeper power-down mode (500 nA) but lacks Quad I/O suspend/resume. | Select when board redesign accommodates SOIC and ultra-low standby current outweighs quad-mode flexibility. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64CVZPJG TR uniquely combines JEDEC SFDP auto-configuration, OTP-locked security registers, and erase/program suspend - making it optimal for secure, field-upgradable embedded systems requiring minimal layout change and robust lifecycle management.

FAQ
What is the package type and footprint of W25Q64CVZPJG TR?
W25Q64CVZPJG TR uses an 8-pin WSON 8x6-mm package (JEDEC MO-241AC, package code ZE) with exposed thermal pad. It shares the same land pattern as Winbond's ZE-coded variants and is not interchangeable with SOIC, PDIP, or TFBGA versions without PCB redesign.
Does W25Q64CVZPJG TR support execute-in-place (XIP) operation?
Yes, W25Q64CVZPJG TR supports true XIP via Continuous Read Mode, requiring only 8 clock cycles to initiate sequential reads after instruction. This enables direct code execution from flash on compatible MCUs like NXP i.MX RT and STMicroelectronics STM32H7 without RAM loading.
How is quad SPI mode enabled on W25Q64CVZPJG TR?
Quad SPI mode on W25Q64CVZPJG TR is activated by setting the Quad Enable (QE) bit in Status Register-2 using the Write Status Register (01h) instruction. Once set, /WP and /HOLD pins become IO2 and IO3, enabling four-line data transfers with instructions like Fast Read Quad I/O (EBh).
What write protection mechanisms does W25Q64CVZPJG TR provide?
W25Q64CVZPJG TR offers layered write protection: hardware via /WP pin (active-low, disabled in quad mode), software via status register bits (BP0–BP2, TB, SEC), and OTP-locked security registers. Protection can be applied to top/bottom 4KB sectors or entire array with configurable granularity.
Is W25Q64CVZPJG TR suitable for automotive applications?
W25Q64CVZPJG TR operates across –40°C to +105°C and meets industrial reliability standards (100,000 cycles, 20-year retention), but is not AEC-Q100 qualified. For automotive use, Winbond's AEC-Q100-certified W25Q64JW variant is recommended; W25Q64CVZPJG TR is suited for under-hood-adjacent industrial controls and infotainment subsystems.
