W25X64VZEIG

The W25X64VZEIG is a 64 Mbit serial Flash memory device in Winbond's SpiFlash® family. It provides non-volatile storage organized as 8M × 8 with an SPI interface and supports Dual Output SPI for accelerated read operations.

Designed for systems with limited space, pins and power, the device operates from a single 2.7 V to 3.6 V supply, supports up to a 75 MHz clock, and targets applications such as code download and storing voice, text and data while fitting a compact 8‑contact WSON package.

Key Features

• Memory Capacity & Organization — 64 Mbit Flash organized as 8M × 8 for code, data, and media storage.
• SPI Interface with Dual Output — Standard SPI interface with Dual Output SPI support to improve read throughput.
• Clock Frequency — Supports up to 75 MHz serial clock for high-speed access.
• Sector Architecture — 4 KB sectors enable granular erase and update operations.
• Write Cycle Time — Word/page write cycle time specified at 3 ms for program operations.
• Power Supply — Single-supply operation from 2.7 V to 3.6 V for easy system integration.
• Package — 8-contact WSON (8 × 6 mm) / 8‑WDFN with exposed pad for compact board mounting.
• Operating Temperature — Rated for −40 °C to 85 °C operating temperature range.

Typical Applications

• Firmware and Code Storage — Suitable for code download and firmware storage where serial Flash is required.
• Voice, Text and Data Storage — Used to store voice, text and general data in space-constrained products.
• Space- and Pin-Constrained Embedded Systems — Compact package and SPI interface fit systems with limited board area and pin count.

Unique Advantages

• Compact, low-footprint package: 8‑contact WSON (8 × 6 mm) / 8‑WDFN with exposed pad reduces PCB area for space-sensitive designs.
• Faster serial reads: 75 MHz clock and Dual Output SPI support enable higher read throughput compared with single-output SPI alone.
• Granular update control: 4 KB sector architecture allows targeted erase/program operations to limit unnecessary data modifications.
• Single-supply convenience: 2.7 V to 3.6 V operating range integrates with common system rails without additional level translation.
• Wide operating range: −40 °C to 85 °C rating supports a broad set of commercial and industrial environments.
• Documented command set and registers: Comprehensive SPI instruction set, status and control registers, and dual output modes are provided for software integration.

Why Choose W25X64VZEIG?

The W25X64VZEIG delivers a practical balance of capacity, speed and compact packaging for embedded designs requiring non-volatile serial storage. Its 64 Mbit organization, 75 MHz SPI interface with Dual Output mode, and 4 KB sector architecture make it suitable for firmware storage and data/voice/text retention in systems where board space and pin count are constrained.

Backed by the SpiFlash® series documentation and a defined SPI instruction set, the device is appropriate for engineers seeking a well-documented, single-supply serial Flash solution with defined write timings and a broad operating temperature range.
