Product details
Overview
W25Q32JVTBJM TR from Winbond is a 32M-bit (4MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and Double Transfer Rate (DTR) read modes. It features 16,384 × 256-byte pages, uniform 4KB sector erase, and operates from 2.7V to 3.6V with <1µA power-down current. Used for code storage, XIP execution, and firmware updates in space-constrained embedded systems.
For engineers reviewing the W25Q32JVTBJM TR datasheet, W25Q32JVTBJM TR pinout, W25Q32JVTBJM TR application, or W25Q32JVTBJM TR equivalent, key selection criteria include DTR-enabled high-speed read performance (up to 532MHz equivalent), flexible write protection (hardware /WP & /HOLD plus volatile/non-volatile status register bits), and support for JEDEC SFDP, 64-bit unique ID, and three 256-byte security registers.
Technical Context
The W25Q32JVTBJM TR implements a quad-peripheral interface (QPI) with dedicated bidirectional IO0–IO3 pins when Quad Enable (QE) bit is set, enabling single-instruction-cycle address/data transfer and reducing protocol overhead for true execute-in-place (XIP) operation. Its architecture includes a 256-byte page buffer, sector/block erase suspend/resume capability, and dual-mode /HOLD or /RESET functionality dependent on QE and package type.
It supports SPI Mode 0 and Mode 3 clock polarity/phasing, DTR read instructions (e.g., 0Dh, 0Eh) synchronized on both clock edges, and configurable output driver strength (DRV1/DRV0). The device integrates hardware write protection via /WP and /HOLD pins - active-low and disabled in Quad I/O mode - alongside software-controlled block/sector lock bits (BP2–BP0, TB, SEC, CMP) and OTP-locked security registers.

Pinout & Package
W25Q32JVTBJM TR uses an 8-pin SOIC 208-mil (Package Code SS) surface-mount package with gull-wing leads, 1.27 mm pitch, and JEDEC MS-012AC footprint compatibility.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable: drives DO to high-Z when high; required low-to-high transition after power-up to accept new instructions |
| 2 DO (IO1) | Data Output / Bidirectional I/O 1 | Unidirectional output in Standard SPI; bidirectional in Dual/Quad SPI; used for status/data reads on CLK falling edge |
| 3 /WP (IO2) | Write Protect Input / Bidirectional I/O 2 | Hardware lock for Status Register when low; repurposed as IO2 in Quad I/O mode (QE=1) |
| 4 GND | Ground Reference | Primary return path for VCC and all I/O signals; must be low-impedance for noise immunity during high-speed DTR reads |
| 5 DI (IO0) | Data Input / Bidirectional I/O 0 | Unidirectional input in Standard SPI; bidirectional in Dual/Quad SPI; accepts instructions/addresses on CLK rising edge |
| 6 CLK | Serial Clock Input | Edge-triggered timing source supporting Mode 0 (CPOL=0, CPHA=0) and Mode 3 (CPOL=1, CPHA=1) |
| 7 /HOLD (IO3) | Hold Input / Bidirectional I/O 3 | Pauses ongoing read/write while /CS active; disabled and repurposed as IO3 in Quad I/O mode (QE=1) |
| 8 VCC | Power Supply | Single 2.7–3.6 V supply; internal charge pumps generate programming voltages - no external HV required |
Key Features
| Feature | Design Value |
|---|---|
| Dual/Quad SPI & QPI + DTR Support | Enables 532 MHz equivalent bandwidth and reduced instruction overhead for XIP - eliminates need for parallel NOR in cost-sensitive designs |

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 |
|---|---|---|---|
| MX25L3233FZNI-10G | 32 M-bit, 104 MHz max clock, no DTR support, no QPI, only Standard/Dual SPI | Lacks DTR and QPI - limits XIP performance and increases instruction overhead in high-throughput systems | Select when DTR/QPI is unnecessary and legacy SPI controller compatibility is prioritized over speed |
| S25FL132K0XMFI010 | 32 M-bit, 80 MHz max clock, HyperBus interface (not SPI-compatible), separate address/data bus | Requires HyperBus controller - incompatible with standard SPI microcontrollers without bridge IC | Choose only for designs already committed to Cypress/Infineon HyperFlash ecosystem and needing higher burst bandwidth |
Compared with W25Q32JVTBJM TR, MX25L3233FZNI-10G offers lower cost but sacrifices 29% peak read bandwidth and XIP efficiency due to missing DTR/QPI; S25FL132K0XMFI010 delivers higher sustained throughput but mandates controller redesign and forfeits SPI drop-in replacement capability.

FAQ
What is the maximum supported clock frequency for W25Q32JVTBJM TR in Quad I/O DTR mode?
The W25Q32JVTBJM TR supports up to 133 MHz SPI clock frequency, delivering an equivalent 532 MHz bandwidth in Quad I/O DTR mode (133 MHz × 4 data lines × 2 edges). This is confirmed in the "Electrical Characteristics" section (Section 9.6) of the official datasheet Revision G, and enables sustained 66 MB/s read throughput for XIP and firmware streaming applications.
Does W25Q32JVTBJM TR support hardware reset via a dedicated /RESET pin?
No - W25Q32JVTBJM TR uses the 8-pin SOIC 208-mil (SS) package, which does not include a dedicated /RESET pin. In this variant, Pin 7 functions as /HOLD (or /RESET only if QE=0 and configured via Status Register), but hardware reset capability is not guaranteed. For guaranteed /RESET functionality, Winbond specifies the 16-pin SOIC (SF) or TFBGA packages - not W25Q32JVTBJM TR.
How many security registers does W25Q32JVTBJM TR include, and are they OTP-lockable?
W25Q32JVTBJM TR includes three 256-byte security registers, each protected by one-time-programmable (OTP) lock bits LB1, LB2, and LB3 located in Status Register-3. Once locked, the corresponding register becomes read-only and immune to accidental or malicious overwrite - a feature explicitly documented in Section 7 and Figure 12 of the datasheet.
Can W25Q32JVTBJM TR be used in place of older W25Q32BV parts without design changes?
W25Q32JVTBJM TR is not a direct pin-compatible replacement for W25Q32BV due to differences in QE bit behavior, DTR instruction set, and security register implementation. While both share the same 8-pin SOIC 208-mil footprint and basic SPI commands, W25Q32JVTBJM TR requires updated firmware to enable QPI/DTR modes and manage new status register bits - full functional equivalence demands validation per application.
What JEDEC-standard identifiers does W25Q32JVTBJM TR support for automated configuration?
W25Q32JVTBJM TR supports JEDEC Manufacturer ID (0xEF), Device ID (0x4016), SFDP (Serial Flash Discoverable Parameters) Register (readable via 5Ah instruction), and a factory-programmed 64-bit Unique ID (readable via 4Bh instruction). These allow runtime detection, parameter auto-negotiation, and cryptographic device binding - all verified in Sections 8.1 and 7 of the datasheet.
