Winbond Electronics Corporation W25Q64FWZPIG

Overview

W25Q64FWZPIG from Winbond is a 1.8V, 64M-bit (8MB) serial NOR flash memory IC supporting Standard/Dual/Quad SPI and QPI interfaces. It delivers 104MHz clock rate (416MHz equivalent Quad I/O), 4KB uniform sector erase, 256-byte page programming, and true execute-in-place (XIP) capability for embedded code storage in microcontroller boot applications.

For engineers reviewing the W25Q64FWZPIG datasheet, W25Q64FWZPIG pinout, W25Q64FWZPIG application, or W25Q64FWZPIG equivalent, this page provides verified pin functions, JEDEC-compliant ID support, 64-bit unique serial number, security register OTP locks, and real-world XIP timing behavior - all confirmed for the ZPIG (8-pin WSON 6×5-mm) package variant.

Technical Context

The W25Q64FWZPIG implements a quad-peripheral interface (QPI) with 2-clock instruction cycle overhead, reducing command latency versus standard SPI. Its status register includes non-volatile Quad Enable (QE), Write Protect Selection (WPS), and HOLD/RESET function control (HOLD/RST), enabling dynamic mode reconfiguration without hardware change.

It supports Erase/Program Suspend & Resume, continuous read with 8/16/32/64-byte wrap, and three 256-byte security registers with one-time-programmable (OTP) lock bits (LB1–LB3). Memory organization comprises 32,768 × 256-byte pages, 4,096 × 4KB sectors, and 256 × 64KB blocks - all accessible via deterministic address mapping per JEDEC JESD216 SFDP.

Key Specifications

Pinout & Package

W25Q64FWZPIG uses an 8-pad WSON 6×5-mm package (JEDEC MO-241AC, Winbond code ZP), with exposed thermal pad (non-electrical). Pin 1 is /CS; pins are arranged in clockwise order from top-left corner under marking dot.

FAQ

What is the package type and footprint compatibility of W25Q64FWZPIG?

W25Q64FWZPIG uses an 8-pad WSON 6×5-mm package (JEDEC MO-241AC, Winbond code ZP) with a 0.5-mm pitch and exposed thermal pad. It shares footprint compatibility with other Winbond WSON-8 variants like W25Q32FWZPIG and W25Q128JWZPIG, enabling scalable memory design across density points without PCB revision.

Does W25Q64FWZPIG support execute-in-place (XIP) operation, and what interface modes enable it?

Yes, W25Q64FWZPIG supports true XIP operation via Continuous Read Mode and Quad SPI/QPI interfaces. Fast Read Quad I/O (EBh), Word Read Quad I/O (E7h), and QPI instructions deliver the low-latency, high-bandwidth access required for direct CPU execution. Standard SPI Fast Read (0Bh) also supports basic XIP but with lower throughput.

How is hardware write protection implemented on W25Q64FWZPIG, and can it coexist with Quad SPI mode?

Hardware write protection on W25Q64FWZPIG uses the /WP pin to lock status register writes when QE=0. When QE=1 (enabling Quad SPI/QPI), /WP becomes IO2 and hardware protection is disabled; instead, non-volatile Block Protect (BP2–BP0), Top/Bottom (TB), and Complement (CMP) bits provide software-configurable array protection - preserving security without sacrificing interface speed.

What is the role of the /HOLD pin on W25Q64FWZPIG, and how does it behave in QPI mode?

The /HOLD pin on W25Q64FWZPIG pauses ongoing SPI transfers while /CS remains low, placing DO in high-impedance and ignoring DI/CLK edges - useful for bus arbitration. In QPI mode (QE=1), /HOLD becomes IO3 and loses its hold function; hold behavior must then be managed via software commands or external logic.

Is W25Q64FWZPIG compatible with JEDEC-standard SFDP, and how is it accessed?

Yes, W25Q64FWZPIG fully complies with JEDEC JESD216B SFDP v1.6. The SFDP register is read using instruction 5Ah, returning structured parameter tables that describe erase timings, voltage ranges, and Quad Enable requirements - enabling automatic, vendor-agnostic driver initialization in RTOS and bare-metal firmware.
