Product details
Overview
W25Q64JVZEJM from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes for high-speed code execution and data storage in space-constrained embedded systems. It operates from 2.7V to 3.6V, delivers up to 133MHz SPI clock rate (532MHz equivalent Quad I/O), features 4KB uniform sectors, 100K program-erase cycles per sector, and 20+ year data retention.
For engineers reviewing the W25Q64JVZEJM datasheet, W25Q64JVZEJM pinout, W25Q64JVZEJM application, or W25Q64JVZEJM equivalent, this device is selected for XIP-capable boot memory, firmware storage with hardware write protection, and industrial-grade parameter logging where low-power standby (<1µA), JEDEC-compliant ID, SFDP register support, and 64-bit unique serial number are required.
Technical Context
The W25Q64JVZEJM implements a flexible SPI-compatible interface with configurable I/O modes: Standard (4-wire), Dual (2 I/O lines), Quad (4 I/O lines), and QPI (4-wire full-duplex). Its architecture supports true execute-in-place (XIP) via Continuous Read Mode with ≤8-clock instruction overhead and wrap lengths of 8/16/32/64 bytes.
It integrates volatile and non-volatile status/configuration registers including Quad Enable (QE), Block Protect (BP2–BP0), Top/Bottom protect (TB), Security Register Locks (LB1–LB3), and Output Driver Strength (DRV1/DRV0), enabling fine-grained memory protection and timing optimization across industrial temperature ranges (−40°C to +105°C).

Pinout & Package
W25Q64JVZEJM is supplied in an 8-pad WSON 8x6-mm package (JEDEC MO-241AC, package code ZE), with exposed pad for thermal dissipation and no internal /RESET pin - /HOLD (IO3) shares pin 7 functionality in Standard/Dual SPI mode only.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; must transition high→low after power-up before accepting instructions |
| 2 DO (IO1) | Data Output / Bidirectional I/O | Unidirectional output in Standard SPI; bidirectional IO1 in Dual/Quad SPI/QPI |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O | Hardware sector lock when low; becomes IO2 in Quad mode (QE=1) |
| 4 GND | Ground Reference | Primary return path; connects to exposed pad for thermal and EMI performance |
| 5 DI (IO0) | Data Input / Bidirectional I/O | Unidirectional input in Standard SPI; bidirectional IO0 in Dual/Quad SPI/QPI |
| 6 CLK | Serial Clock Input | Edge-triggered timing source; supports SPI Modes 0 and 3; max 133 MHz |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O | Pauses ongoing transfer while /CS active; becomes IO3 in Quad mode (QE=1) |
| 8 VCC | Power Supply | 2.7–3.6 V core and I/O supply; decoupling capacitor required near pin |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead via 4-wire full-duplex protocol - eliminates repeated opcode transmission during burst reads |
| DTR (Double Transfer Rate) Read | Enables data sampling on both clock edges in Fast Read DTR modes (0Dh, BDh, EDh) - doubles effective bandwidth without increasing clock frequency |
| Erase/Program Suspend & Resume | Allows background erase or program to be paused for higher-priority operations (e.g., real-time interrupt handling), then resumed without data loss |
| Volatile & Non-Volatile Status Registers | Enables runtime configuration (e.g., driver strength, hold/reset function mapping) while preserving critical settings like QE and BP bits across power cycles |
| Individual Sector Lock via Security Registers | Three 256-byte OTP-lockable registers allow secure storage of keys or calibration data - locked permanently after programming |
| Continuous Read with Wrap | Supports seamless sequential access across page boundaries using 8/16/32/64-byte wrap - essential for deterministic XIP execution latency |

FAQ
What is the package type and pin count of W25Q64JVZEJM?
W25Q64JVZEJM uses an 8-pad WSON package measuring 8 mm × 6 mm (package code ZE), with no /RESET pin. Pin functions include /CS, DO (IO1), /WP (IO2), GND, DI (IO0), CLK, /HOLD (IO3), and VCC. This compact footprint supports high-density PCB layouts while maintaining full Dual/Quad SPI and QPI functionality.
Does W25Q64JVZEJM support hardware reset functionality?
No, W25Q64JVZEJM does not include a dedicated hardware /RESET pin. The /HOLD pin (pin 7) can serve as /RESET only in specific configurations of other packages (e.g., TFBGA or 16-pin SOIC), but in the ZE package, pin 7 is strictly /HOLD (IO3) in Standard/Dual mode and IO3 in Quad mode - no hardware reset capability is implemented.
How does W25Q64JVZEJM enable execute-in-place (XIP) operation?
W25Q64JVZEJM enables true XIP through Continuous Read Mode with ≤8-clock instruction overhead and configurable wrap lengths (8/16/32/64 bytes), combined with high-speed Quad I/O and QPI interfaces. This allows microcontrollers to fetch and execute code directly from flash without copying to RAM - reducing latency and system memory requirements.
What security features are implemented in W25Q64JVZEJM?
W25Q64JVZEJM includes hardware write protection (/WP pin), top/bottom/complement sector locking (TB, BP, SEC, CMP bits), three 256-byte OTP-lockable security registers, a 64-bit unique serial number, JEDEC-standard manufacturer/device ID, and an SFDP v1.6 register - collectively enabling secure boot, firmware authentication, and tamper-resistant parameter storage.
Is W25Q64JVZEJM compatible with standard SPI controllers?
Yes, W25Q64JVZEJM is fully backward-compatible with standard SPI controllers using Mode 0 or Mode 3. It supports all standard SPI instructions (e.g., Read Data 03h, Page Program 02h) on pins /CS, CLK, DI, and DO. Dual/Quad SPI, QPI, and DTR modes are optional enhancements activated via status register configuration and extended instructions.
