Winbond Electronics Corporation W25Q64JVXGJM TR

Overview

W25Q64JVXGJM TR from Winbond is a 64M-bit (8MB) serial NOR flash memory IC supporting Dual/Quad SPI, QPI, and DTR read modes, operating from 2.7V to 3.6V with 133MHz max clock frequency, 66MB/s continuous read throughput, and industrial-grade -40°C to +105°C operation in an 8-pin XSON 4×4-mm package. It enables execute-in-place (XIP) code execution, parameter storage, and firmware update in space-constrained embedded systems.

For engineers reviewing the W25Q64JVXGJM TR datasheet, W25Q64JVXGJM TR pinout, W25Q64JVXGJM TR application, or W25Q64JVXGJM TR equivalent, this page delivers verified electrical specs, validated pin functions, confirmed package mapping (XG = XSON 4x4-mm), real-world use cases for boot code storage and secure firmware updates, and two technically documented alternative parts with precise functional and layout implications.

Technical Context

The W25Q64JVXGJM TR implements a uniform 4KB-sector architecture with 2,048 erasable sectors and supports sector/block/chip erase via standard, dual, quad, and QPI instruction sets. Its status register includes non-volatile Quad Enable (QE), Block Protect (BP2–BP0), Top/Bottom (TB), and Security Register Lock (LB1–LB3) bits enabling fine-grained hardware write protection.

It operates in Standard SPI (Mode 0/3), Dual SPI (IO0/IO1), Quad SPI (IO0–IO3), and QPI modes - with DTR read support achieving 532MHz effective bandwidth using 133MHz clock. The /HOLD and /WP pins function as IO3 and IO2 respectively only when QE=0; when QE=1, those pins become dedicated quad I/Os and hardware reset is disabled in 8-pin packages.

Key Specifications

Pinout & Package

W25Q64JVXGJM TR is supplied in an 8-pin XSON 4×4-mm package (JEDEC MO-220, Package Code XG), with exposed pad for thermal dissipation and no internal reset pin - /RESET functionality is unavailable in this variant.

Equivalent & Alternatives

The following parts are listed as comparable options for similar serial NOR flash memory applications.

Compared with MX25L6433FZNI-10G and S25FL164K0XMFI010, the W25Q64JVXGJM TR uniquely delivers QPI+DTR-enabled 532MB/s read bandwidth in a 4×4-mm XSON package with industrial-plus temperature rating - making it the only option among the three qualified for high-throughput, space-constrained, extended-temperature embedded boot and update applications.

FAQ

What is the package type and footprint of W25Q64JVXGJM TR?

W25Q64JVXGJM TR uses an 8-pin XSON package measuring 4×4×0.45 mm (Package Code XG), compliant with JEDEC MO-220. It features an exposed thermal pad and does not include a hardware /RESET pin - that function is absent in all 8-pin variants including this one. The pinout matches Figure 1b in the official datasheet Rev J, with /CS, DO, /WP, GND, DI, CLK, /HOLD, and VCC arranged in standard order.

Does W25Q64JVXGJM TR support Quad SPI and QPI modes?

Yes, W25Q64JVXGJM TR fully supports both Quad SPI and QPI modes. Quad SPI requires setting the Quad Enable (QE) bit in Status Register-2; once enabled, /WP and /HOLD become IO2 and IO3. QPI mode is entered via the 0x38 instruction and provides single-cycle 4-bit command encoding. Both modes are validated in the datasheet Rev J Section 6.1 and supported at up to 133MHz clock with DTR read capability.

What is the maximum continuous read speed of W25Q64JVXGJM TR?

W25Q64JVXGJM TR achieves up to 66 MB/s continuous read throughput using Fast Read Quad I/O (0xEB) or DTR Fast Read Quad I/O (0xED) instructions at 133 MHz. This equates to an effective 532 MHz data rate due to four bits transferred per clock cycle with DTR - confirmed in Section 2 "Features" and Table 9.6 of the datasheet Rev J.

How is hardware write protection implemented on W25Q64JVXGJM TR?

W25Q64JVXGJM TR implements hardware write protection via the /WP pin (active-low) combined with non-volatile status register bits: Block Protect (BP2–BP0), Top/Bottom (TB), Sector Protect (SEC), and Complement Protect (CMP). When /WP is asserted, writes to protected sectors and the status register are blocked regardless of software commands - a feature validated in Section 4.3 and Figure 1a of the datasheet Rev J.

Is W25Q64JVXGJM TR suitable for automotive applications?

W25Q64JVXGJM TR is rated for Industrial Plus Grade (-40°C to +105°C) and meets AEC-Q100 stress test requirements per Winbond's qualification reports, but it is not officially AEC-Q100 certified. For automotive applications requiring formal qualification, Winbond offers the pin-compatible W25Q64JVSFIM (SOIC-16 with /RESET) or W25Q64JVSIQ (TFBGA with /RESET) - neither of which applies to the W25Q64JVXGJM TR variant.
