Winbond Electronics Corporation W25Q01JVTBIM

Overview

W25Q01JVTBIM from Winbond is a 1G-bit (128MB) dual-die serial flash memory supporting Dual/Quad SPI, QPI, and Double Transfer Rate (DTR) read modes with 133MHz clock, 4KB uniform sectors, and -40°C to +85°C operation. It delivers 66MB/s continuous data transfer and supports XIP (execute-in-place) for code storage in embedded microcontrollers, IoT edge nodes, and industrial HMIs.

For engineers reviewing the W25Q01JVTBIM datasheet, W25Q01JVTBIM pinout, W25Q01JVTBIM application, or W25Q01JVTBIM equivalent, key selection criteria include 4-byte addressing support, quad I/O enable (QE bit), hardware reset availability, IO pin multiplexing behavior, and package-specific /RESET vs /HOLD functionality.

Technical Context

The W25Q01JVTBIM implements a two-die stacked architecture delivering linear 1G-bit address space, with independent BUSY and SUS status bits per die. It supports 3- and 4-byte addressing modes, configurable output driver strength (DRV1/DRV0), and volatile/non-volatile status register bits including Quad Enable (QE), Top/Bottom protect (TB), and Security Register Lock (LB1–LB3).

Its interface flexibility includes Standard SPI (DI/DO), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), and QPI/DTR protocols - all operating on a single 2.7V–3.6V supply. The /HOLD and /WP pins are repurposed as IO3 and IO2 respectively when QE=1, and hardware /RESET is available only on SOIC-16 and TFBGA packages - not on the 8-pin WSON.

Key Specifications

Pinout & Package

W25Q01JVTBIM uses the 24-ball TFBGA 8x6-mm package (Package Code TB, 5×5 ball array), with dedicated /RESET pin and full Quad I/O support. Pin functions are defined per JEDEC-compliant ball map.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial flash memory applications.

Compared with W25Q01JVTBIM, W25Q01JVSFIM offers guaranteed hardware reset isolation but sacrifices compactness, while MX25L1G48E trades bandwidth and architectural transparency for cross-supplier qualification familiarity - neither is pin-compatible, and both require firmware and layout review.

Availability

W25Q01JVTBIM is available at Aetrix Electronics and suitable for industrial HMIs, edge AI sensor nodes, medical diagnostic equipment, and factory automation controllers requiring stable component supply across multi-year production cycles.

Supply support for W25Q01JVTBIM includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs.

FAQ

What package type does W25Q01JVTBIM use, and how is it identified?

W25Q01JVTBIM uses the 24-ball TFBGA 8x6-mm package with 5×5 ball array (Package Code TB). This is confirmed by Winbond's official ordering information table and top-side marking specification. The "TB" suffix in the part number directly denotes this TFBGA variant, distinguishing it from WSON (ZE) and SOIC (SF) versions of the same die.

Does W25Q01JVTBIM support hardware reset, and how is it implemented?

Yes, W25Q01JVTBIM supports hardware reset via a dedicated /RESET pin located at ball A4 in its TFBGA package. Unlike the 8-pin WSON version, this pin is not multiplexed - it functions exclusively as a reset input. Driving it low for ≥1 µs forces the device into its power-on state, terminating all ongoing operations regardless of current mode or status register settings.

How does Quad SPI mode affect pin functionality on W25Q01JVTBIM?

In Quad SPI mode, W25Q01JVTBIM reassigns /WP (ball C4) to IO2 and /HOLD (ball D4) to IO3, enabled by setting the non-volatile Quad Enable (QE) bit in Status Register-2. This conversion is mandatory for Quad operation and means hardware write protection and hold functions are disabled when QE=1 - design must rely on software-based protection or alternate control strategies.

What is the significance of the "DTR" in W25Q01JVTBIM's full designation W25Q01JV-DTR?

The "DTR" suffix indicates Double Transfer Rate capability - meaning W25Q01JVTBIM supports DTR read instructions (e.g., 0Dh, BDh, EDh) where data is sampled on both rising and falling edges of CLK. This doubles effective throughput versus standard SPI reads, achieving up to 532MHz equivalent bandwidth in Quad DTR mode, critical for high-speed code fetch and streaming applications.

Can W25Q01JVTBIM be used in 4-byte addressing mode, and how is it enabled?

Yes, W25Q01JVTBIM fully supports 4-byte addressing for accessing its full 1G-bit address space. It is enabled by issuing the Enter 4-Byte Address Mode instruction (B7h), which sets the ADP bit in Status Register-1. The setting persists after power cycle if ADP is written as non-volatile; otherwise, it defaults to 3-byte mode on power-up and requires re-enabling in firmware initialization.
