Product details
Overview
W25Q128JVCJM TR from Winbond is a 128M-bit (16MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI, QPI, and DTR read modes. It operates from 2.7V to 3.6V, delivers up to 133MHz SPI clock (532MHz equivalent Quad I/O), features uniform 4KB sectors, 100K program-erase cycles per sector, and 20-year data retention. It is used for XIP code execution, firmware storage, and parameter logging in industrial microcontroller systems.
For engineers reviewing the W25Q128JVCJM TR datasheet, W25Q128JVCJM TR pinout, W25Q128JVCJM TR application, or W25Q128JVCJM TR equivalent, key selection criteria include DTR timing compliance, /RESET pin availability in SOIC-16 or TFBGA packages, QE bit configuration for Quad I/O mode, and hardware write protection via /WP and /HOLD pins on 8-pin variants.
Technical Context
The W25Q128JVCJM TR implements a multi-mode serial interface with configurable I/O count: Standard SPI uses DI/DO unidirectionally; Dual/Quad SPI and QPI use IO0–IO3 bidirectionally when Quad Enable (QE) is set in Status Register-2. Its architecture supports continuous read with wrap (8/16/32/64-byte), enabling true execute-in-place (XIP) operation with only 8 clocks overhead for address setup.
It integrates volatile/non-volatile status register bits for flexible protection (BP2–BP0, TB, SEC, CMP, SRP), erase/program suspend/resume, and three 256-byte security registers with OTP locks. The /RESET pin is dedicated in SOIC-16 and TFBGA packages but multiplexed with /HOLD on 8-pin SOIC/WSON when QE=0.

Equivalent & Alternatives
The following parts are listed as comparable options for similar serial NOR flash applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MX25L12833FZNI-10G | 128M-bit, 104MHz max clock, no DTR support, SOIC-8/WSON-8 packages only | Lacks DTR and QPI modes; lower bandwidth limits XIP performance in high-throughput applications | Select when DTR/QPI are unused and cost sensitivity outweighs speed requirements |
| S25FL128SAGMFI000 | 128M-bit, 133MHz, supports DTR and QPI, but requires separate /RESET pin (SOIC-16/TFBGA only); no /HOLD multiplexing | Dedicated /RESET improves reset reliability but increases pin count; no /HOLD fallback in 8-pin variants | Select when deterministic hardware reset is mandatory and board layout accommodates SOIC-16 or TFBGA |
Compared with MX25L12833FZNI-10G and S25FL128SAGMFI000, the W25Q128JVCJM TR uniquely combines DTR timing, QPI mode, and /HOLD–/RESET multiplexing in its 8-pin WSON package - enabling high-speed XIP in space-constrained industrial designs without sacrificing reset flexibility.

FAQ
What is the package type and footprint of the W25Q128JVCJM TR?
The W25Q128JVCJM TR uses an 8-pin WSON 6×5-mm package (Package Code P) with an exposed thermal pad. It is pin-compatible with other Winbond W25Q128JV variants in the same WSON-8 format, and its land pattern matches JEDEC MO-241AC standards. This compact footprint supports high-density PCB layouts in industrial and portable electronics where board space is constrained.
Does the W25Q128JVCJM TR support hardware reset, and how is it implemented?
The W25Q128JVCJM TR does not include a dedicated /RESET pin - it uses the /HOLD pin (Pin 7) in multiplexed mode. When the Quad Enable (QE) bit in Status Register-2 is cleared (QE=0), Pin 7 functions as /HOLD; when QE=1, it becomes IO3 and /RESET is unavailable. For guaranteed hardware reset, Winbond recommends the SOIC-16 or TFBGA variants of the W25Q128JV family instead of the W25Q128JVCJM TR.
How does the W25Q128JVCJM TR enable execute-in-place (XIP) functionality?
The W25Q128JVCJM TR enables true XIP through Continuous Read Mode with wrap (8/16/32/64-byte) and low instruction overhead (as few as 8 clocks to address memory). Combined with Quad SPI and DTR read instructions (e.g., EDh), it achieves up to 66 MB/s sustained throughput - allowing microcontrollers to fetch and execute code directly from flash without intermediate RAM buffering, reducing system BOM and boot latency.
What write protection mechanisms are available on the W25Q128JVCJM TR?
The W25Q128JVCJM TR provides layered write protection: hardware via the /WP pin (active-low, protects status register), and software via status register bits (BP2–BP0, TB, SEC, CMP, SRP). These allow selective locking of 4KB sectors, top/bottom array regions, or the entire memory. Protection persists across power cycles when configured as non-volatile, and the /WP pin remains functional only when QE=0 - otherwise IO2 replaces /WP in Quad mode.
Is the W25Q128JVCJM TR compatible with standard SPI controllers, and what interface modes does it support?
Yes, the W25Q128JVCJM TR is fully backward-compatible with standard SPI controllers using Mode 0 or Mode 3. It natively supports Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), QPI, and DTR read modes. All modes share the same physical pins, with Quad and QPI requiring the non-volatile Quad Enable (QE) bit to be set in Status Register-2 - ensuring seamless integration across legacy and next-generation host interfaces.
