Product details

Overview

W25Q64CVZEJG TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard, Dual, and Quad SPI interfaces with up to 80MHz clock frequency, 4KB uniform sector erase granularity, and true execute-in-place (XIP) capability for embedded code storage. It operates from 2.7V–3.6V, draws 4mA active current and <1µA in power-down mode, and is qualified for industrial temperature range (−40°C to +85°C). It is used in microcontroller boot code storage, firmware update storage, and parameter retention in IoT edge nodes.

For engineers reviewing the W25Q64CVZEJG TR datasheet, W25Q64CVZEJG TR pinout, W25Q64CVZEJG TR application, or W25Q64CVZEJG TR equivalent, key selection considerations include Quad SPI enable (QE bit), 4KB sector flexibility, hardware write protection via /WP and /HOLD pins, JEDEC ID and SFDP register support, and compatibility with XIP-capable MCU boot loaders.

Technical Context

The W25Q64CVZEJG TR implements a SPI command-set architecture with three operational modes: Standard (4-wire), Dual I/O (5-wire), and Quad I/O (6-wire), where IO0–IO3 are dynamically reassigned from dedicated DI/DO/WP/HOLD functions upon setting the non-volatile Quad Enable (QE) bit in Status Register-2. Its internal block diagram integrates a 256-byte page buffer, sector/block erase logic, security registers, and SFDP register for discoverable parameters.

It supports full instruction-level compatibility with JEDEC JESD216B SFDP v1.6, enabling automatic configuration by host controllers; erase suspend/resume allows background operation interruption; and 64-bit unique ID provides device-level traceability. The device uses floating-gate NOR technology with >100,000 program/erase cycles and >20-year data retention at 85°C.

Key Features

Feature	Design Value
Quad SPI with QE bit control	Enables 320 MHz effective throughput and true XIP execution; requires explicit QE=1 programming before Quad instructions
Continuous Read Mode	Reduces instruction overhead to ≤8 clocks per 24-bit address; enables efficient linear code fetch for MCU boot and runtime execution
4 KB uniform sector architecture	Allows fine-grained firmware partitioning (e.g., bootloader + app + config), minimizing erase wear during field updates
Three 256-byte security registers	OTP-lockable storage for keys, calibration data, or device-specific credentials; protected by LB1–LB3 bits
SFDP v1.6 compliance	Enables automatic host controller configuration (clock mode, dummy cycles, address width) without hard-coded driver assumptions
Erase/Program Suspend & Resume	Permits interrupt-driven operation: pause erase/program to service higher-priority tasks, then resume without data loss

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 Quad SPI clock; supports DTR mode; different SFDP layout and QE bit location	Higher bandwidth but requires updated driver for DTR and extended address modes; not drop-in compatible	Choose for bandwidth-critical designs needing >320 MB/s effective throughput and willing to modify SPI controller firmware.
S25FL164K0XMFI010	64 M-bit, 80 MHz Quad SPI; HyperBus interface option; different security register structure and no OTP lock bits	Lacks OTP-locked security registers; supports HyperFlash protocol for alternate high-speed interface	Choose when HyperBus compatibility is needed or when security register OTP locking is not required for the use case.

Compared with W25Q64CVZEJG TR, MX25L6433FZNI-10G offers higher clock rate but demands driver changes, while S25FL164K0XMFI010 provides HyperBus flexibility at the cost of OTP-based security register protection - making W25Q64CVZEJG TR optimal for cost-sensitive, XIP-focused industrial designs requiring robust, field-proven security and minimal firmware adaptation.

FAQ

What is the package type and lead count of W25Q64CVZEJG TR?

W25Q64CVZEJG TR uses an 8-pad WSON package measuring 8 mm × 6 mm (JEDEC MO-241AC, package code ZE), with gull-wing leads and wettable flanks for reliable solder joint inspection. It has 8 electrical terminals: /CS, DO(IO1), /WP(IO2), GND, DI(IO0), CLK, /HOLD(IO3), and VCC - no NC pins.

Does W25Q64CVZEJG TR support Quad SPI out of the box?

No - W25Q64CVZEJG TR requires explicit programming of the Quad Enable (QE) bit in Status Register-2 to activate Quad SPI mode. Until QE=1 is written, /WP and /HOLD remain dedicated hardware control pins. This prevents accidental mode change and ensures backward compatibility with Standard SPI systems.

How many program/erase cycles does W25Q64CVZEJG TR guarantee?

W25Q64CVZEJG TR guarantees more than 100,000 program/erase cycles per sector under industrial conditions (−40°C to +85°C), verified per AEC-Q100 stress testing protocols. Full-chip erase endurance is rated at >10,000 cycles. Data retention exceeds 20 years at +85°C.

Can W25Q64CVZEJG TR be used for execute-in-place (XIP) operation?

Yes - W25Q64CVZEJG TR supports true XIP via Continuous Read Mode with ≤8-clock instruction overhead and Fast Read Quad I/O (EBh) instructions. When paired with an XIP-capable MCU (e.g., STM32H7, NXP i.MX RT), it enables direct code execution from flash without RAM loading, reducing boot time and memory footprint.

What security features does W25Q64CVZEJG TR provide beyond basic write protection?

W25Q64CVZEJG TR includes three 256-byte security registers with one-time-programmable (OTP) lock bits (LB1–LB3), 64-bit unique serial number per device, SFDP register for standardized parameter discovery, and volatile/non-volatile status register protection (SRP0/SRP1). These enable secure key storage, device authentication, and tamper-resistant configuration.
