Product details
Overview
W25Q128JVFJM TR from Winbond is a 128M-bit (16MB) serial NOR flash memory supporting Standard/Dual/Quad SPI, QPI, and DTR read modes. It operates from 2.7V to 3.6V, delivers up to 133MHz clock rate (532MHz equivalent Quad I/O), features uniform 4KB sectors, 100K program-erase cycles per sector, and 20-year data retention. It serves as nonvolatile code storage and XIP execution memory in microcontroller boot systems.
For engineers reviewing the W25Q128JVFJM TR datasheet, W25Q128JVFJM TR pinout, W25Q128JVFJM TR application, or W25Q128JVFJM TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin availability per package, DTR timing compliance, and sector protection granularity for firmware update safety.
Technical Context
The W25Q128JVFJM TR implements a flexible SPI-compatible command set with volatile/non-volatile status register control (BP2–BP0, TB, SEC, QE, DRV0/DRV1, HOLD/RST). Its architecture supports true execute-in-place (XIP) via Continuous Read Mode with ≤8-clock instruction overhead and wrap lengths of 8/16/32/64 bytes.
It integrates three 256-byte security registers with OTP locks, JEDEC-standard 64-bit unique ID, SFDP register for discoverable parameters, and hardware write protection using /WP and /HOLD pins - both repurposed as IO2/IO3 when QE=1 in Quad mode. Erase suspend/resume and power-down (<1µA typical) enable low-power embedded operation.

Pinout & Package
W25Q128JVFJM TR uses an 8-pin WSON 6×5-mm package (Package Code P), with exposed pad for thermal dissipation. Pin functions are defined per JEDEC-standard SOIC/WSON layout and validated for this exact variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| /CS | Chip Select Input | Active-low enable; places DO/IO pins in high-impedance state when deasserted; required to transition high→low before new instruction acceptance |
| DO (IO1) | Data Output / I/O1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad modes; used for status/data reads on CLK falling edge |
| /WP (IO2) | Write Protect Input / I/O2 | Hardware lock for status register writes; disabled as IO2 when Quad Enable (QE) bit = 1 |
| GND | Ground Reference | Primary signal and power return path; must be low-impedance for stable read/write timing and noise immunity |
| DI (IO0) | Data Input / I/O0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad modes; accepts instructions/addresses on CLK rising edge |
| CLK | Serial Clock Input | Master-generated timing reference; supports SPI Mode 0 and Mode 3; determines max interface speed and setup/hold margins |
| /HOLD (IO3) | Hold Input / I/O3 | Pauses ongoing read/write without deselecting device; disabled as IO3 when QE = 1 |
| VCC | Power Supply | Single 2.7–3.6 V supply; powers internal charge pumps, logic, and I/O buffers; requires local 100 nF decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Quad Peripheral Interface (QPI) | Reduces instruction overhead by encoding commands in 4-bit nibbles - enables faster sequential access than standard SPI |
| DTR (Double Transfer Rate) Read | Transfers data on both clock edges during read operations - doubles effective bandwidth without increasing clock frequency |
| Continuous Read with Wrap | Supports 8/16/32/64-byte burst wraps - eliminates address increment overhead for streaming code or audio buffers |
| Individual Sector Lock | Allows per-sector (4 KB) write protection via 32-bit lock bits - isolates bootloader, calibration data, and user settings |
| Security Registers (3 × 256 B) | OTP-lockable nonvolatile storage for keys, certificates, or device-specific secrets - separate from main array and protected by LB1–LB3 bits |

FAQ
What is the package type and footprint of W25Q128JVFJM TR?
W25Q128JVFJM TR uses an 8-pin WSON 6×5-mm package (JEDEC MO-241AC) with exposed thermal pad. This matches Package Code P in Winbond's documentation and is distinct from SOIC-208, SOIC-300, or TFBGA variants. The pinout is identical to the W25Q128JV-DTR SOIC/WSON baseline, confirmed in Section 3.2 and 3.3 of the datasheet.
Does W25Q128JVFJM TR support Quad SPI and QPI modes?
Yes, W25Q128JVFJM TR supports both Quad SPI and QPI modes. Quad SPI requires setting the non-volatile Quad Enable (QE) bit in Status Register-2. QPI mode is entered via the 0x38 command and exited with 0xFF. Both modes use IO0–IO3 bidirectionally and are fully documented in Sections 6.1.3 and 6.1.4 of the datasheet.
How does the /HOLD pin function differ between Standard SPI and Quad SPI on W25Q128JVFJM TR?
In Standard SPI mode, /HOLD (Pin 7) pauses ongoing operations while /CS remains low. In Quad SPI mode, that same pin becomes IO3 and loses /HOLD functionality - confirmed in Notes 2 of Section 3.3 and Section 4.4. The W25Q128JVFJM TR datasheet explicitly states /HOLD is unavailable when QE=1.
What is the maximum clock frequency supported by W25Q128JVFJM TR in DTR mode?
W25Q128JVFJM TR supports DTR (Double Transfer Rate) read instructions up to 133 MHz clock frequency, achieving 266 MHz effective data rate in Dual I/O DTR and 532 MHz in Quad I/O DTR - specified in Section 1 (General Descriptions) and Table 9.6 (AC Electrical Characteristics).
Can W25Q128JVFJM TR be used for secure firmware storage with cryptographic key protection?
Yes, W25Q128JVFJM TR includes three 256-byte security registers with OTP lock bits (LB1–LB3), a 64-bit unique ID, and SFDP register support. Keys can be written once and permanently locked, preventing runtime readout - detailed in Sections 2 (Features), 7.1.9, and 8.2.31–8.2.34 of the datasheet.
