Product details
Overview
W25Q64CVSSJP 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 erase architecture, and hardware write protection via /WP and /HOLD pins. It operates from 2.7V–3.6V, draws 4 mA active current and <1 µA in power-down mode, and is used for code storage, XIP execution, and firmware parameter retention in embedded microcontrollers.
For engineers reviewing the W25Q64CVSSJP TR datasheet, W25Q64CVSSJP TR pinout, W25Q64CVSSJP TR application, or W25Q64CVSSJP TR equivalent, key selection criteria include Quad SPI enable (QE bit), 4KB sector granularity, JEDEC ID compatibility, SFDP register support, and SOIC-8 (208-mil) package mechanical fit.
Technical Context
The W25Q64CVSSJP TR implements a SPI command set compliant with JEDEC JESD216 SFDP v1.5, enabling auto-configuration of read latencies and timing parameters. Its dual/quad I/O operation requires non-volatile QE bit (Status Register-2, bit 1) to be set, repurposing /WP and /HOLD as IO2 and IO3 - disabling hardware write protect during Quad mode.
It features three 256-byte security registers with OTP locks, a 64-bit unique serial number, and erase/program suspend-resume capability. The 32,768 × 256-byte page array supports page program (up to 256 bytes), 4KB sector/32KB block/64KB block/chip erase, and continuous read mode with ≤8-clock instruction overhead for true execute-in-place (XIP) operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 M-bit (8 MB); enables compact firmware storage without parallel bus footprint |
| Interface Support | Standard/Dual/Quad SPI; allows scalable bandwidth: 80 MHz single-line → 320 MHz effective quad-rate |
| Erase Granularity | Uniform 4 KB sectors (2,048 total); permits fine-grained firmware update and parameter partitioning |
| Write Endurance | 100,000 program/erase cycles; supports field-upgradable firmware with long service life |
| Data Retention | 20 years at +85°C; ensures reliable boot code and calibration data persistence in industrial environments |
| Operating Voltage | 2.7 V to 3.6 V; compatible with 3.3 V logic systems and brown-out tolerant power rails |
| Power Consumption | 4 mA active, <1 µA power-down (typ.); reduces standby power in battery-backed or energy-sensitive designs |
Pinout & Package
W25Q64CVSSJP TR uses an 8-pin SOIC-208-mil (package code SS) with standard SPI pinout and dual/quad I/O flexibility. Pin functions are fixed per physical position; /WP and /HOLD serve as hardware protection inputs in Standard/Dual mode but become IO2/IO3 in Quad mode when QE=1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select input | Active-low enable: high-Z DO and low-power standby when deasserted; required high→low transition after power-up |
| 2 DO (IO1) | Serial data output / bidirectional I/O | Unidirectional output in Standard SPI; becomes bidirectional IO1 in Dual/Quad mode for read/write multiplexing |
| 3 /WP (IO2) | Hardware write protect / bidirectional I/O | Active-low lock for status register; repurposed as IO2 in Quad mode (QE=1), disabling hardware protection |
| 4 GND | Ground reference | Signal and power return path; must be low-impedance for stable SPI timing and noise immunity |
| 5 DI (IO0) | Serial data input / bidirectional I/O | Unidirectional input in Standard SPI; becomes bidirectional IO0 in Dual/Quad mode for full-duplex command/address/data |
| 6 CLK | Serial clock input | Edge-triggered timing source; supports Mode 0 and Mode 3; max 80 MHz for reliable setup/hold margins |
| 7 /HOLD (IO3) | Hold control / bidirectional I/O | Pauses ongoing SPI transaction while /CS remains low; repurposed as IO3 in Quad mode (QE=1) |
| 8 VCC | Power supply | Single 2.7–3.6 V rail; decoupling capacitor (0.1 µF) required near pin for transient current stability |
Key Features
| Feature | Design Value |
|---|---|
| Quad Enable (QE) bit | Non-volatile Status Register-2 bit controls permanent IO2/IO3 remapping - enables high-speed Quad I/O without external logic |
| Continuous Read Mode | ≤8-clock instruction overhead per 24-bit address; eliminates repeated command reissue for sequential XIP access |
| SFDP Register (JESD216) | Discoverable flash parameters (read latency, dummy cycles, erase types); enables automatic driver initialization without hard-coded timing |
| Security Registers | Three 256-byte OTP-lockable regions for secure keys, calibration data, or device-specific credentials |
| Erase/Program Suspend | Interrupts long erase/program operations to service higher-priority tasks; resumes from exact byte offset without data loss |
| 64-bit Unique ID | Factory-programmed serial number per die; supports device authentication, traceability, and license binding |

FAQ
What is the package type and lead count of W25Q64CVSSJP TR?
W25Q64CVSSJP TR uses an 8-pin SOIC-208-mil (package code SS) with standard gull-wing leads. This surface-mount package measures 5.3 mm × 5.3 mm × 1.95 mm and is RoHS-compliant. It is mechanically and electrically identical to the VSOP-208 variant but optimized for automated assembly and thermal performance in industrial PCB layouts.
Does W25Q64CVSSJP TR support Quad SPI mode out of the box?
No - W25Q64CVSSJP TR requires the Quad Enable (QE) bit in Status Register-2 to be set (via Write Status Register instruction 01h) before Quad SPI operation is enabled. Until then, /WP and /HOLD function as hardware write protect and hold inputs. Setting QE=1 permanently reassigns those pins to IO2 and IO3, disabling hardware protection during Quad mode.
How does the 4KB sector architecture benefit firmware update design?
The uniform 4KB sector erase structure of W25Q64CVSSJP TR allows precise, non-disruptive firmware patching - only modified sectors need erasing and rewriting. This minimizes update time, reduces wear on unmodified regions, and enables dual-bank OTA schemes where one sector holds active code while another receives new firmware, improving system uptime and reliability.
Can W25Q64CVSSJP TR be used in automotive applications?
W25Q64CVSSJP TR is rated for -40°C to +85°C operation and meets industrial reliability standards. While not AEC-Q100 qualified itself, it is widely deployed in automotive infotainment and ADAS subsystems where ambient temperature stays within spec. For full AEC-Q100 compliance, Winbond offers the pin-compatible W25Q64JW variant - verify qualification status per your Tier-1 requirements before deployment.
What is the purpose of the SFDP register in W25Q64CVSSJP TR?
The SFDP (Serial Flash Discoverable Parameters) register in W25Q64CVSSJP TR provides standardized, read-only metadata about timing parameters (e.g., read latency, dummy cycles), erase capabilities, and protection features. This enables host MCU drivers to auto-configure without hardcoded values - improving firmware portability across voltage, temperature, and revision changes.
