Winbond Electronics Corporation W25Q128JVBIM TR

Overview

W25Q128JVBIM TR from Winbond is a 128M-bit (16MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes. It operates from 2.7V to 3.6V, delivers up to 133MHz SPI clock rate (532MHz equivalent Quad I/O), features 4KB uniform sectors, 100K program-erase cycles per sector, and -40°C to +85°C industrial temperature range. It is used for XIP code execution, firmware storage, and parameter retention in microcontroller-based embedded systems.

For engineers reviewing the W25Q128JVBIM TR datasheet, W25Q128JVBIM TR pinout, W25Q128JVBIM TR application, or W25Q128JVBIM TR equivalent, key selection criteria include Quad Enable (QE) bit configuration, /HOLD vs /RESET pin availability by package, DTR timing compliance, and sector protection granularity for secure firmware updates.

Technical Context

The W25Q128JVBIM TR implements a flexible SPI-compatible interface with mode-selectable operation: Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), and QPI (all four IOs as bidirectional). Its command set includes DTR Fast Read (0Dh, BDh, EDh) requiring precise setup/hold timing on CLK and data lines relative to DTR enable state.

Internally, it uses a 65,536-page (256-byte/page) array organized into 4,096 × 4KB sectors and 256 × 64KB blocks. Erase/suspend/resume functionality, volatile/non-volatile status register bits (BP2–BP0, TB, SEC, QE, DRV0/DRV1), and three 256-byte security registers support robust firmware integrity and field-upgrade safety.

Key Specifications

Pinout & Package

FAQ

What is the package type and pin count of W25Q128JVBIM TR?

W25Q128JVBIM TR uses an 8-pin WSON 6×5-mm package (Package Code P) with an exposed thermal pad. It has eight terminals: /CS, DO (IO1), /WP (IO2), GND, DI (IO0), CLK, /HOLD (IO3), and VCC. This matches the pinout shown in Winbond's W25Q128JV-DTR datasheet Figure 1b and Section 3.2–3.3.

Does W25Q128JVBIM TR support Quad SPI and QPI modes?

Yes, W25Q128JVBIM 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 using instruction 38h and exited with FFh. Both modes use IO0–IO3 bidirectionally and require QE=1; /WP and /HOLD functions are disabled in these modes.

What is the maximum clock frequency supported by W25Q128JVBIM TR in DTR mode?

W25Q128JVBIM TR supports up to 133 MHz SPI clock frequency. In DTR mode (e.g., DTR Fast Read 0Dh/BDh/EDh), this yields effective data rates of 266 Mbps (Dual I/O) or 532 Mbps (Quad I/O), as confirmed in the "Highest Performance Serial Flash" feature list and AC Electrical Characteristics table of the datasheet.

How many program-erase cycles does W25Q128JVBIM TR guarantee per sector?

W25Q128JVBIM TR guarantees a minimum of 100,000 program-erase cycles per sector, as specified in the "Features" section and Electrical Characteristics table of the official Winbond W25Q128JV-DTR datasheet Rev. C. This endurance rating applies to all 4KB sectors across the full 128M-bit array.

Is the /RESET pin available on W25Q128JVBIM TR?

No, W25Q128JVBIM TR does not include a dedicated /RESET pin. As an 8-pin WSON device, it uses the /HOLD pin (Pin 7) which can be configured as /RESET only in 16-pin SOIC or TFBGA packages. In W25Q128JVBIM TR, /HOLD remains functional in Standard/Dual SPI but is repurposed as IO3 in Quad/QPI modes.
