Product details
Overview
W25Q64FVTCJQ TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating at up to 104 MHz clock frequency with 50 MB/s continuous read throughput, 4 KB uniform sector erase granularity, and single 2.7–3.6 V supply - deployed for code execution (XIP), firmware storage, and parameter retention in embedded microcontroller boot systems.
For engineers reviewing the W25Q64FVTCJQ TR datasheet, W25Q64FVTCJQ TR pinout, W25Q64FVTCJQ TR application, or W25Q64FVTCJQ TR equivalent, key selection considerations include Quad Enable (QE) bit configuration for IO2/IO3 remapping, /WP and /HOLD pin availability in selected package, 4KB sector protection granularity, and JEDEC SFDP register support for auto-configuration.
Technical Context
The W25Q64FVTCJQ TR implements a flexible SPI-compatible command set with hardware-accelerated erase/program suspend-resume, volatile/non-volatile status registers (including QE bit in Status Register-2), and three 256-byte security registers with OTP locks. It supports SPI Mode 0 and Mode 3, with dual/quad I/O enabled only after QE=1 is written to Status Register-2.
Its architecture features 32,768 × 256-byte programmable pages, 2,048 erasable 4KB sectors, and 128 erasable 64KB blocks. Continuous Read Mode reduces instruction overhead to just 8 clocks for address setup, enabling true execute-in-place (XIP) operation without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 64 M-bit (8 MB) - sufficient for full MCU boot images, firmware binaries, and persistent configuration data in space-constrained designs. |
| Interface Support | Standard SPI, Dual SPI, Quad SPI, and QPI - enables scalable bandwidth: 104 MHz (104 MB/s single-line), 208 MB/s (dual), 416 MB/s (quad/QPI). |
| Erase Granularity | Uniform 4 KB sectors - allows fine-grained firmware update partitioning and secure parameter storage without disturbing adjacent code regions. |
| Write Endurance | 100,000 program/erase cycles - supports field firmware updates over multi-year product lifetimes in industrial controllers and IoT edge nodes. |
| Data Retention | 20 years at +85°C - ensures reliable long-term storage of calibration data, device IDs, and security keys in automotive and industrial environments. |
| Supply Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and tolerant of brown-out conditions during power sequencing. |
| Operating Temperature | −40°C to +85°C - qualified for extended temperature operation in outdoor gateways, motor drives, and factory automation equipment. |
Pinout & Package
W25Q64FVTCJQ TR uses an 8-pin TFBGA 8×6-mm package (package code TC, 6×4 ball array), with pins arranged in a compact surface-mount footprint optimized for high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| B2 | CLK | Serial clock input - timing reference for all SPI/QPI operations; must meet tCH/tCL ≥ 4.8 ns per datasheet AC specs. |
| B3 | GND | Digital ground reference - requires low-impedance connection to system ground plane to minimize noise coupling into SPI signaling. |
| B4 | VCC | Power supply input - decoupling capacitor (≥100 nF) required within 3 mm of this pin for stable core voltage during fast read bursts. |
| C2 | /CS | Chip select input - active-low enable signal; must transition high→low before each new instruction sequence to reset internal state machine. |
| C4 | /WP (IO2) | Hardware write protect input (or IO2 in Quad mode) - when QE=0, provides hardware-level lock for status register writes; disabled as /WP when QE=1. |
| D2 | DO (IO1) | Data output (or IO1 in Dual/Quad mode) - bidirectional in enhanced modes; high-impedance when /CS is high or /HOLD is asserted. |
| D3 | DI (IO0) | Data input (or IO0 in Dual/Quad mode) - receives commands, addresses, and program data; latched on rising CLK edge in Standard SPI. |
| D4 | /HOLD (IO3) | Hold input (or IO3 in Quad mode) - pauses ongoing read/write transfers without deselecting device; disabled as /HOLD when QE=1. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead to 2 clocks per byte vs. 8+ in Standard SPI - enables deterministic XIP latency critical for real-time MCU boot and interrupt response. |
| Erase/Program Suspend & Resume | Allows background firmware update while servicing time-critical interrupts - suspends active erase/program to service DO reads or status queries within 2 µs. |
| 64-bit Unique ID | Factory-programmed per-device serial number - eliminates need for external EEPROM or one-time-programmable fuses for device authentication and traceability. |
| JEDEC SFDP Register | Standardized flash parameter table accessible via 5Ah command - enables automatic driver configuration without hard-coded timing or geometry assumptions. |
| Security Registers (3 × 256 B) | OTP-lockable memory regions for cryptographic keys, calibration coefficients, or license tokens - isolated from main array and inaccessible without explicit unlock sequence. |
Applications
| Industrial PLC Firmware Storage | Automotive ADAS Boot Memory |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L6433FZNI-10G | 64 M-bit, 104 MHz max, SOIC-8 only; lacks QPI mode and SFDP register; no security registers. | Suitable for cost-sensitive consumer devices where XIP latency and secure key storage are not required. | Select if board layout already uses SOIC-8 and QPI/SFDP/security features are unnecessary. |
| S25FL164K0XMFI010 | 64 M-bit, 80 MHz max, supports HyperBus interface; includes 128-bit unique ID but no OTP security registers. | Better for high-throughput streaming applications using Cypress's HyperFlash protocol instead of SPI/QPI. | Choose only when migrating from existing HyperBus-based designs - not drop-in SPI replacement. |
Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64FVTCJQ TR uniquely combines QPI mode, JEDEC SFDP, and OTP-locked security registers in a TFBGA package - making it optimal for secure, high-speed, auto-configurable embedded boot systems requiring minimal software porting effort.

FAQ
What is the package type and pin count of the W25Q64FVTCJQ TR?
The W25Q64FVTCJQ TR uses an 8×6-mm TFBGA package with a 6×4 ball array (24-ball footprint, package code TC). It has eight functional terminals: /CS, CLK, DI (IO0), DO (IO1), /WP (IO2), /HOLD (IO3), VCC, and GND - with four NC balls. This compact form factor supports high-density routing in space-limited applications like wearable medical devices and compact industrial sensors.
Does the W25Q64FVTCJQ TR support execute-in-place (XIP) operation?
Yes, the W25Q64FVTCJQ TR supports true XIP via its Continuous Read Mode and Quad Peripheral Interface (QPI). With as few as 8 clocks for address setup and 416 MB/s effective read bandwidth in QPI mode, it enables direct code execution from flash without RAM loading - reducing boot time and SRAM footprint in Cortex-M and RISC-V microcontrollers.
How is hardware write protection implemented on the W25Q64FVTCJQ TR?
The W25Q64FVTCJQ TR implements hardware write protection through the /WP pin (active-low) in conjunction with status register bits (BP2–BP0, TB, SEC, CMP). When /WP is held low and status register protection is enabled (SRP0/SRP1 = 1), writes to protected 4KB sectors or the entire array are blocked - providing fail-safe protection against accidental firmware corruption during power transients or software faults.
What is the role of the Quad Enable (QE) bit in the W25Q64FVTCJQ TR?
The Quad Enable (QE) bit - located in Status Register-2 - must be set to '1' to activate Quad SPI and QPI modes. When QE=1, the /WP and /HOLD pins are remapped to IO2 and IO3 respectively, enabling four-line bidirectional data transfer. This bit is non-volatile and persists across power cycles, ensuring consistent interface behavior after reset.
Can the W25Q64FVTCJQ TR be used in automotive applications?
Yes, the W25Q64FVTCJQ TR is rated for −40°C to +85°C operation and meets AEC-Q100 stress test requirements for Grade 3 components. Its 20-year data retention, 100,000 erase/program cycles, and hardware-based sector protection make it suitable for automotive infotainment boot storage, ADAS sensor calibration tables, and telematics firmware - provided board-level qualification per vehicle OEM specifications is completed.
