Product details
Overview
W25Q128JVEJM TR from Winbond is a 3.3V, 128M-bit (16MB) serial NOR flash memory with Dual/Quad SPI, QPI and DTR interfaces, organized as 65,536 × 256-byte pages and supporting 4KB/32KB/64KB erase granularity. It delivers up to 133MHz SPI clock rate, 66MB/s continuous read throughput, and operates across –40°C to +105°C for industrial-plus applications including boot code storage and firmware update in embedded controllers.
For engineers reviewing the W25Q128JVEJM TR datasheet, W25Q128JVEJM TR pinout, W25Q128JVEJM TR application, or W25Q128JVEJM TR equivalent, key selection considerations include its 8-pin WSON 8x6-mm (Package Code E) footprint, /HOLD and /WP dual-function pins configurable via Status Register-2 QE bit, DTR-enabled high-speed read modes, and hardware reset support only in SOIC-16/TFBGA variants-not in this WSON variant.
Technical Context
The W25Q128JVEJM TR implements a quad I/O SPI architecture where IO0–IO3 serve bidirectional data paths under QPI or Quad SPI mode, enabled by non-volatile Quad Enable (QE) bit in Status Register-2. Its command set includes DTR Fast Read (0Dh), DTR Quad I/O (EDh), and Burst Read with Wrap (0Ch), all requiring precise setup timing per AC specs.
It integrates three 256-byte Security Registers with OTP locks, JEDEC SFDP register for discoverable parameters, and flexible write protection via volatile/non-volatile BP2–BP0, TB, SEC, CMP, and SRP bits-allowing sector-level lockdown independent of software control flow.

Pinout & Package
W25Q128JVEJM TR uses an 8-pad WSON 8×6 mm package (Package Code E), with exposed thermal pad. Pin functions are identical to SOIC-8 but in surface-mount land-grid layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 /CS | Chip Select Input | Active-low enable; must transition high→low before instruction acceptance; high-impedance DO when deasserted |
| 2 DO (IO1) | Data Output / Quad I/O 1 | Unidirectional output in Standard SPI; bidirectional I/O in Dual/Quad SPI/QPI; requires QE=1 for Quad role |
| 3 /WP (IO2) | Write Protect Input / Quad I/O 2 | Hardware lock for Status Register writes; disabled as /WP and repurposed as IO2 when QE=1 |
| 4 GND | Ground Reference | Primary return path for VCC and I/O signals; connects to thermal pad for thermal dissipation |
| 5 DI (IO0) | Data Input / Quad I/O 0 | Unidirectional input in Standard SPI; bidirectional I/O in Dual/Quad SPI/QPI; always active in all modes |
| 6 CLK | Serial Clock Input | Edge-triggered timing reference; supports SPI Mode 0 and Mode 3; max 133 MHz frequency |
| 7 /HOLD (IO3) | Hold Input / Quad I/O 3 | Pauses ongoing read/write without deselecting; disabled as /HOLD and repurposed as IO3 when QE=1 |
| 8 VCC | Power Supply | 2.7–3.6 V supply; decoupling capacitor required within 5 mm of pin per layout guidelines |
Key Features
| Feature | Design Value |
|---|---|
| Dual/Quad SPI + QPI + DTR support | Enables 66 MB/s continuous read via EDh/EDh-DTR, reducing boot latency vs. legacy SPI flash |
| Uniform 4KB sector architecture | Allows independent firmware partitioning (e.g., bootloader, app, config) without cross-sector erasure |
| Erase/Program Suspend & Resume | Permits background firmware download while servicing real-time interrupts via SUS/RES commands |
| Three 256-byte Security Registers | Stores cryptographic keys or calibration data with OTP lock bits, preventing runtime overwrite or readout |
| JEDEC SFDP register | Provides standardized, host-readable memory map and timing parameters-eliminates hard-coded driver assumptions |
| Top/Bottom array protection | Hardware-enforced lockdown of boot sectors (top) or user data (bottom) using TB and BP bits |

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 |
|---|---|---|---|
| MX25L12833FZNI-08G | 128Mb, 3V, 104MHz max clock, no DTR support, 8-pin SOIC only | Lacks DTR and QPI; lower bandwidth limits XIP performance in resource-constrained hosts | Choose when board uses SOIC-8 footprint and DTR/QPI are unused; verify /RESET not required |
| S25FL128SAGMFI000 | 128Mb, 3V, 133MHz, supports DTR but no QPI; 8-pin WSON 6x5mm (P-code) | Same speed class but missing QPI instruction set; incompatible with QPI-based boot ROMs | Select if host controller uses only SPI/DTR and space is constrained to 6x5mm; confirm QE-dependent pin remapping not needed |
Compared with W25Q128JVEJM TR, MX25L12833FZNI-08G offers simpler interface compatibility but sacrifices 29% peak bandwidth and XIP efficiency, while S25FL128SAGMFI000 matches speed and package size but omits QPI-requiring firmware changes for legacy QPI-boot designs.

FAQ
What is the package type and footprint of W25Q128JVEJM TR?
W25Q128JVEJM TR uses an 8-pad WSON package measuring 8 mm × 6 mm (Package Code E) with an exposed thermal pad. It shares pinout compatibility with other W25Q128JV variants in WSON-8 format, including identical pin numbering and function mapping per datasheet Figure 1b and Section 3.2.
Does W25Q128JVEJM TR support hardware reset (/RESET) functionality?
No, W25Q128JVEJM TR does not provide a dedicated /RESET pin. The /HOLD pin (Pin 7) can be configured as /RESET only in SOIC-16 or TFBGA packages per datasheet Section 4.6; the WSON-8 variant (E-code) lacks this capability and relies solely on software reset (66h + 99h) or power-cycle recovery.
How is Quad SPI mode enabled on W25Q128JVEJM TR?
Quad SPI mode on W25Q128JVEJM TR is enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2 (SR2) using Write Status Register-2 (31h) instruction. Once QE = 1, Pins 3 (/WP) and 7 (/HOLD) become IO2 and IO3 respectively, completing the four-line I/O bus required for Quad operations.
What is the maximum continuous read data rate achievable with W25Q128JVEJM TR?
W25Q128JVEJM TR achieves up to 66 MB/s continuous read throughput using DTR Quad I/O (EDh) at 133 MHz clock, as specified in datasheet Section 2 "Features". This assumes optimal PCB layout, proper termination, and host controller support for DTR timing modes.
Can W25Q128JVEJM TR be used for secure key storage?
Yes, W25Q128JVEJM TR includes three 256-byte Security Registers with OTP lock bits (LB1–LB3) that permanently disable further writes or reads once programmed. These registers are electrically isolated from main array access and support secure storage of cryptographic keys, calibration secrets, or device-unique credentials.
