Product details
Overview
W25Q32FVTCIG TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating at 2.7–3.6V with 104MHz max clock rate and 50MB/s continuous read throughput. It features uniform 4KB sectors, 64KB blocks, and supports execute-in-place (XIP) for code storage in embedded microcontrollers, IoT edge nodes, and firmware update buffers.
For engineers reviewing the W25Q32FVTCIG TR datasheet, W25Q32FVTCIG TR pinout, W25Q32FVTCIG TR application, or W25Q32FVTCIG TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin mapping per package, sector protection granularity, SFDP register support, and power-down current (<1µA typical).
Technical Context
The W25Q32FVTCIG TR implements a dual-mode I/O architecture: Standard SPI uses dedicated DI/DO pins, while Quad SPI repurposes /WP and /HOLD as IO2/IO3 when QE=1 in Status Register-2. Its command set includes Fast Read Quad I/O (EBh), Word Read Quad I/O (E7h), and Octal Word Read (E3h), enabling true XIP with ≤8-clock address overhead.
Memory organization comprises 16,384 × 256-byte pages across 1,024 erasable 4KB sectors and 64 erasable 64KB blocks. Erase/program suspend/resume, volatile/non-volatile status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1), and three 256-byte OTP-locked security registers provide robust data integrity control.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Memory Density | 32 M-bit (4 MB) - supports full firmware images for mid-tier MCUs without external memory expansion. |
| Interface Modes | Standard SPI / Dual SPI / Quad SPI / QPI - enables scalable bandwidth: 104MHz single-line, 208MHz dual, 416MHz quad-equivalent. |
| Read Throughput | 50 MB/s continuous - sufficient for real-time audio streaming or fast boot code execution from flash. |
| Erase Granularity | 4 KB sectors, 32 KB & 64 KB blocks - allows fine-grained parameter storage and coarse firmware partitioning. |
| Endurance & Retention | 100,000 program/erase cycles, 20-year data retention - meets industrial lifecycle requirements for field-deployed devices. |
| Power Supply | 2.7 V to 3.6 V - compatible with 3.3 V logic rails and brown-out tolerant in battery-backed systems. |
| Standby Current | <1 µA (typ.) in power-down mode - critical for always-on sensor nodes and energy-harvesting applications. |
Pinout & Package
W25Q32FVTCIG TR is supplied in an 8-pin TSSOP (Thin Shrink Small Outline Package) 208-mil body (JEDEC MS-012AC), with lead finish matte tin and RoHS-compliant construction. Pin 1 is marked by a beveled corner.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: high = device deselected (high-Z outputs, standby current); low = active communication window. |
| 2 DO (IO1) | Data Output / Quad I/O Line 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes; used for status/data reads. |
| 3 /WP (IO2) | Write Protect Input / Quad I/O Line 2 | Hardware lock for status register writes; repurposed as IO2 when QE=1 - disables hardware WP in Quad mode. |
| 4 GND | Ground Reference | Signal and power return path; must be low-impedance to minimize noise coupling during high-speed reads. |
| 5 DI (IO0) | Data Input / Quad I/O Line 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes; carries instructions, addresses, data. |
| 6 CLK | Serial Clock Input | Synchronous timing reference; rising edge latches inputs, falling edge samples outputs; max 104 MHz. |
| 7 /HOLD (IO3) | Hold Input / Quad I/O Line 3 | Pauses ongoing transfers without deselecting; repurposed as IO3 when QE=1 - disables HOLD in Quad mode. |
| 8 VCC | Power Supply | 2.7–3.6 V supply; requires local 100 nF ceramic decoupling near pin to suppress switching noise. |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead via 2-clock-cycle opcodes, enabling deterministic XIP latency and simplified controller firmware. |
| Continuous Read Mode | Supports 8/16/32/64-byte wrap with only 8 clocks to initiate address fetch - eliminates repeated instruction overhead for sequential access. |
| Erase/Program Suspend & Resume | Allows background erase or program to pause for higher-priority reads/writes - essential for real-time logging and OTA updates. |
| 64-bit Unique ID | Factory-programmed per-device serial number - enables secure device authentication and firmware binding in connected systems. |
| SFDP Register Support | JEDEC JESD216-compliant flash parameter table - permits automatic driver configuration without hard-coded timing or geometry tables. |

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 |
|---|---|---|---|
| MX25L3233FZC-10G | 32M-bit, 104MHz max clock, but lacks QPI mode and SFDP register; uses legacy instruction set. | No native XIP optimization; requires custom driver tuning for burst reads; no auto-discovery of timing parameters. | Prefer W25Q32FVTCIG TR where QPI, SFDP, or suspend/resume are required; MX25L3233FZC-10G suits cost-sensitive legacy designs. |
| S25FL132K0XMFI010 | 32M-bit, 80MHz max clock, supports HyperBus interface (not SPI/QPI); different pinout and command set. | Requires HyperFlash controller; incompatible with standard SPI peripherals; higher pin count (16-pin SOIC). | W25Q32FVTCIG TR is drop-in for SPI-based systems; S25FL132K0XMFI010 only viable if HyperBus PHY and layout are already committed. |
Compared with MX25L3233FZC-10G and S25FL132K0XMFI010, the W25Q32FVTCIG TR delivers superior XIP performance via QPI and Continuous Read, broader ecosystem support through SFDP, and field-proven suspend/resume for mixed-read/write workloads - making it optimal for next-generation connected and safety-aware devices.

FAQ
What is the package type and lead finish of W25Q32FVTCIG TR?
W25Q32FVTCIG TR is packaged in an 8-pin TSSOP (208-mil) with matte tin lead finish, compliant with JEDEC MS-012AC and RoHS Directive 2011/65/EU. The 'TCIG' suffix denotes this specific TSSOP variant, and 'TR' indicates tape-and-reel packaging for automated assembly.
Does W25Q32FVTCIG TR support Quad SPI mode out of the box?
No - W25Q32FVTCIG TR requires the Quad Enable (QE) bit in Status Register-2 to be set (via Write Status Register-2 instruction 31h) before /WP and /HOLD pins function as IO2 and IO3. Until QE=1, those pins retain their Standard SPI roles; improper QE configuration will cause communication failure in Quad mode.
How does the /HOLD pin behave when QE=1 in W25Q32FVTCIG TR?
When QE=1 in W25Q32FVTCIG TR, the /HOLD pin is repurposed as IO3 for Quad SPI operation and loses its hold functionality. The pin becomes bidirectional and participates in data transfer; asserting low on this pin during active communication will corrupt the transaction rather than pause it.
Can W25Q32FVTCIG TR be used for execute-in-place (XIP) applications?
Yes - W25Q32FVTCIG TR supports true XIP via Continuous Read Mode and QPI, achieving ≤8-clock instruction overhead for sequential access. Its 50MB/s read throughput and deterministic latency make it suitable for direct code execution in Cortex-M, RISC-V, and other embedded processors with SPI/XIP-capable memory controllers.
What security features are implemented in W25Q32FVTCIG TR?
W25Q32FVTCIG TR includes hardware write protection (/WP pin), top/bottom/complement sector locking, individual block/sector lock/unlock commands, three 256-byte OTP-locked security registers, a 64-bit unique ID, and SFDP register for standardized parameter discovery - collectively enabling layered firmware integrity and device identity management.
