Product details
Overview
W25Q32JVDAIQ TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC designed for code storage and data logging in space-constrained embedded systems. It supports Standard, Dual, and Quad SPI interfaces with up to 133 MHz clock rate, delivers 66 MB/s continuous read throughput, operates from 2.7V–3.6V, and features 4KB uniform sectors for flexible firmware partitioning - deployed in industrial microcontroller boot loaders and IoT sensor node firmware storage.
For engineers reviewing the W25Q32JVDAIQ TR datasheet, W25Q32JVDAIQ TR pinout, W25Q32JVDAIQ TR application, or W25Q32JVDAIQ TR equivalent, key selection criteria include Quad SPI XIP capability, hardware write protection via /WP and /HOLD pins, JEDEC-compliant SFDP register access, and industrial temperature support (−40°C to +85°C).
Technical Context
The W25Q32JVDAIQ TR implements a quad I/O SPI interface requiring the non-volatile Quad Enable (QE) bit in Status Register-2 to be set; when enabled, /WP becomes IO2 and /HOLD becomes IO3. Its command set includes Fast Read Quad I/O (EBh) for 532 MHz equivalent bandwidth and Erase/Program Suspend (75h) for real-time interrupt handling during flash operations.
Internally organized as 16,384 pages of 256 bytes each, it supports sector (4KB), block (32KB/64KB), and chip erase with ≥100,000 program-erase cycles per sector and >20-year data retention. Security features include three 256-byte OTP-capable security registers, 64-bit unique ID, and configurable top/bottom/complement array protection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 M-bit (4 MB) - sufficient for full MCU firmware images and parameter tables in compact edge devices. |
| SPI Interface Modes | Standard / Dual / Quad SPI - enables scalable bandwidth: 133 MHz single, 266 MHz dual, 532 MHz quad-equivalent transfer rates. |
| Operating Voltage | 2.7 V to 3.6 V - compatible with standard 3.3 V logic rails and brown-out tolerant in industrial power environments. |
| Temperature Range | −40°C to +85°C - certified for industrial-grade operation without derating or external thermal management. |
| Erase Granularity | Uniform 4 KB sectors (1,024 total) - allows fine-grained firmware updates without disturbing adjacent configuration or calibration data. |
| Endurance & Retention | ≥100,000 program-erase cycles per sector; >20 years data retention - meets long-life requirements for unattended field-deployed equipment. |
| Power-Down Current | 1 µA (typ.) - enables ultra-low-power sleep states in battery-powered sensors and wearables. |

Pinout & Package
W25Q32JVDAIQ TR is supplied in an 8-pin PDIP 300-mil package (Package Code DA), with lead-free, RoHS-compliant finish and industrial-grade reliability screening.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: drives device into active mode only when low; high-impedance DO output and standby current when high. |
| 2 DO (IO1) | Data Output / Quad I/O 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes - carries read data or address bits depending on instruction phase. |
| 3 /WP (IO2) | Write Protect Input / Quad I/O 2 | Hardware lock for status register writes; repurposed as IO2 in Quad mode when QE=1 - enables hardware-firmware coordinated protection. |
| 4 GND | Ground Reference | Primary return path for all internal circuitry and I/O drivers - must be low-impedance and decoupled near VCC pin. |
| 5 DI (IO0) | Data Input / Quad I/O 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes - carries instructions, addresses, and write data on rising CLK edge. |
| 6 CLK | Serial Clock Input | Master-synchronized timing reference for all SPI transactions - supports Mode 0 and Mode 3; max 133 MHz frequency defines system throughput ceiling. |
| 7 /HOLD (IO3) | Hold Input / Quad I/O 3 | Pauses ongoing SPI transaction without deselecting device; repurposed as IO3 in Quad mode - critical for multi-device bus arbitration. |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply powers core logic, charge pumps, and I/O buffers - requires local 100 nF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Quad SPI XIP Support | Enables direct code execution from flash via Fast Read Quad I/O (EBh), eliminating RAM copy overhead and reducing BOM cost in resource-limited MCUs. |
| Erase/Program Suspend | Allows interruption of long erase or program cycles using 75h/7Ah commands - essential for real-time systems needing deterministic latency guarantees. |
| Configurable Hardware Write Protection | /WP pin + volatile/non-volatile BP bits provide layered protection: hardware lock prevents accidental status register corruption during field updates. |
| JEDEC SFDP Register | Standardized, read-only register (5Ah) delivers vendor-agnostic timing, density, and command-set metadata - simplifies automated flash initialization in bootloader frameworks. |
| 64-Bit Unique Serial Number | Factory-programmed per-device ID enables secure device identity binding in OTA update authentication and asset tracking applications. |

FAQ
What is the maximum clock frequency supported by the W25Q32JVDAIQ TR in Quad SPI mode?
The W25Q32JVDAIQ TR supports up to 133 MHz on the serial clock (CLK) pin in Quad SPI mode. When using Fast Read Quad I/O (EBh) instructions, this yields an effective data transfer rate of 532 MHz (133 MHz × 4), enabling high-speed code shadowing and XIP execution without external buffering. This specification is validated across the full −40°C to +85°C industrial temperature range.
Does the W25Q32JVDAIQ TR include hardware reset functionality?
No, the W25Q32JVDAIQ TR does not include a dedicated hardware /RESET pin. That feature is only available on SOIC-16 and TFBGA packages (e.g., W25Q32JVSIQ or W25Q32JVBYIQ). The W25Q32JVDAIQ TR uses PDIP-8 packaging, which supports only /HOLD functionality on Pin 7 - software reset via 66h/99h command sequence remains fully functional.
How is write protection implemented on the W25Q32JVDAIQ TR?
Write protection on the W25Q32JVDAIQ TR combines hardware and software methods: the /WP pin (Pin 3) provides hardware-level lock for status register writes when pulled low, while non-volatile Block Protect (BP2–BP0), Top/Bottom (TB), and Complement (CMP) bits in Status Registers 1 and 2 enable sector- or block-level software-defined protection. Both mechanisms must be configured correctly to prevent unintended firmware corruption.
Can the W25Q32JVDAIQ TR be used for execute-in-place (XIP) applications?
Yes, the W25Q32JVDAIQ TR supports true execute-in-place (XIP) operation via Fast Read Quad I/O (EBh) and Continuous Read with wrap instructions. With 532 MHz equivalent bandwidth and low-latency page-access architecture, it enables MCUs to fetch and execute code directly from flash - reducing RAM usage and boot time in resource-constrained designs such as industrial gateways and wireless sensor nodes.
What package type is used for the W25Q32JVDAIQ TR part number?
The W25Q32JVDAIQ TR uses an 8-pin PDIP (Plastic Dual In-line Package) with 300-mil body width (Package Code DA), lead-free and RoHS-compliant. This through-hole package supports manual prototyping, legacy board assembly, and applications requiring mechanical robustness and thermal cycling resilience in industrial environments.
