Winbond Electronics Corporation W25Q128FVPJQ TR

Overview

W25Q128FVPJQ TR from Winbond is a 128M-bit (16MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces, operating at up to 104 MHz clock frequency with 50 MB/s continuous read throughput. It features uniform 4KB sectors (4,096 total), 32KB/64KB blocks, 256-byte page programming, and supports execute-in-place (XIP) operation. Used for code storage, firmware boot, and parameter retention in microcontroller-based embedded systems.

For engineers reviewing the W25Q128FVPJQ TR datasheet, W25Q128FVPJQ TR pinout, W25Q128FVPJQ TR application, or W25Q128FVPJQ TR equivalent, key selection criteria include Quad SPI enable (QE bit), /HOLD vs /RESET pin behavior per package, sector-level write protection granularity, JEDEC ID/SFDP register support, and 2.7–3.6V single-supply compatibility with <1 µA power-down current.

Technical Context

The W25Q128FVPJQ TR implements a flexible SPI-compatible command set with volatile/non-volatile status registers controlling block protection (BP2–BP0), top/bottom lock (TB), security register locks (LB3–LB1), and quad enable (QE). Its architecture supports concurrent erase/program suspend/resume and individual sector/block locking via dedicated instructions (36h/39h/3Dh).

It delivers true XIP capability via Continuous Read Mode (8-clock address overhead) and QPI mode (reduced instruction overhead), enabling direct code execution from flash. The device uses a 65,536 × 256-byte page array, with erase cycles rated ≥100,000 and data retention >20 years at +25°C.

FAQ

What interface protocols does the W25Q128FVPJQ TR support?

The W25Q128FVPJQ TR supports Standard SPI, Dual I/O SPI, Quad I/O SPI, and Quad Peripheral Interface (QPI). QPI mode reduces instruction overhead and enables faster sequential reads. Quad operation requires setting the Quad Enable (QE) bit in Status Register-2. All modes operate with a single 2.7–3.6 V supply and share the same physical pins (IO0–IO3), with /WP and /HOLD repurposed as IO2 and IO3 when QE=1. The W25Q128FVPJQ TR datasheet specifies timing for each mode up to 104 MHz clock frequency.

How is write protection implemented on the W25Q128FVPJQ TR?

W25Q128FVPJQ TR implements multi-layer write protection: hardware via /WP pin (active-low, effective only when QE=0), and software via status register bits (BP2–BP0, TB, SEC, CMP, SRP0/SRP1). These bits allow locking of top/bottom array halves, individual 4KB sectors, or entire blocks. The /WP pin protects status register writes; BP bits protect corresponding memory regions. Protection persists through power cycles when configured as non-volatile. The W25Q128FVPJQ TR also supports OTP-locked security registers (LB1–LB3) for immutable key storage.

Does the W25Q128FVPJQ TR support execute-in-place (XIP) operation?

Yes, the W25Q128FVPJQ TR supports true XIP via Continuous Read Mode and QPI. Continuous Read requires only 8 clocks to initiate address access and supports wrap lengths of 8/16/32/64 bytes, minimizing instruction overhead. QPI further reduces command latency, enabling efficient instruction fetch directly from flash without buffering. This capability is validated across the W25Q128FV family and confirmed in the W25Q128FVPJQ TR datasheet under "Efficient Continuous Read and QPI Mode".

What is the purpose of the /HOLD and /RESET functions on the W25Q128FVPJQ TR?

On the W25Q128FVPJQ TR's 8-pin WSON package, Pin 7 serves dual function: /HOLD (when QE=0) or /RESET (when QE=0 and HOLD/RST bit = 1 in Status Register-3), but not both simultaneously. /HOLD pauses ongoing SPI transfers while /CS remains low; /RESET performs hardware initialization. When QE=1, Pin 7 becomes IO3 and neither function is available. The W25Q128FVPJQ TR does not include a dedicated /RESET pin in this package-unlike the 16-pin SOIC variant-so software reset (66h/99h) or power cycle is required if Quad mode is used.

What packaging and compliance information applies to the W25Q128FVPJQ TR?

W25Q128FVPJQ TR is packaged in an 8-pin WSON 6×5-mm body (Package Code P) with wettable flanks and RoHS-compliant, lead-free finish. It meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL3) and operates across –40°C to +85°C. The "TR" suffix denotes tape-and-reel packaging (1,000 units per reel). This package is optimized for automated SMT assembly and thermal performance in dense PCB layouts. The W25Q128FVPJQ TR conforms to Winbond's industrial-grade qualification standards, including AEC-Q100 stress testing for the broader W25Q128FV family.
