W74M12FVSSIQ

The W74M12FVSSIQ is a 128 Mbit serial NAND Flash memory device in an 8-pin SOIC package. It provides a compact, non-volatile storage solution with SPI, Dual and Quad I/O support and on-device secure authentication features for embedded systems.

Designed for space- and power-constrained designs, the device supports execute-in-place (XIP) and code shadowing to RAM, and is suitable for storing code, voice, text and data where a small footprint, moderate density and security functions are required.

Key Features

• Memory Density & Organization — 128 Mbit capacity organized as 16M × 8 for byte-oriented access and code/data storage.
• Interface — Standard SPI with Dual/Quad I/O support (IO0–IO3) for higher throughput and flexible connection options.
• Performance — SPI clock frequencies supported up to 104 MHz (Dual/Quad Fast Read modes enable higher effective data rates).
• Secure Authentication — Authentication Flash features including HMAC-related commands, root key register operations and a monotonic counter as documented in the device instruction set.
• Identification & Security Registers — JEDEC standard manufacturer/device ID and SFDP support, a 64-bit unique serial number and three 256-byte security registers.
• Voltage & Power — Operates from a single 2.7 V to 3.6 V supply with low current consumption noted in device description.
• Package & Temperature — Available in 8-pin SOIC (0.209", 5.30 mm width) package; operating temperature range −40 °C to 85 °C (TA).
• Technology — Non-volatile NAND Flash memory optimized for serial SPI operation.

Typical Applications

• Embedded firmware storage — Use the W74M12FVSSIQ for code shadowing to RAM or execute-in-place (XIP) via Dual/Quad SPI to store system firmware and boot code.
• Consumer and industrial devices — Store configuration, text or voice data in space-constrained products that require a 128 Mbit non-volatile memory with secure authentication.
• Security-enabled systems — Leverage on-device authentication functions (HMAC, root key operations, monotonic counter) for integrity and authentication workflows.

Unique Advantages

• Compact footprint: The 8-SOIC package (0.209" / 5.30 mm width) saves board area while providing a full-featured serial Flash interface.
• Flexible high-throughput I/O: Dual and Quad SPI support plus high SPI clock capability (up to 104 MHz) enable higher effective data rates for read-intensive applications.
• Integrated security primitives: Built-in authentication flash commands, HMAC-related functionality and a monotonic counter simplify implementation of secure boot and data authentication.
• Wide system compatibility: 2.7 V–3.6 V supply and industrial operating temperature range (−40 °C to 85 °C) align with common 3 V embedded platforms.
• Device identification and protection: JEDEC ID, SFDP, a 64-bit unique serial number and dedicated security registers support device management and protection schemes.

Why Choose W74M12FVSSIQ?

The W74M12FVSSIQ combines a moderate 128 Mbit NAND Flash density with Dual/Quad SPI performance and on-chip authentication features in a small SOIC package. It is suited to designs that require compact, non-volatile storage with the option to accelerate read throughput via Dual/Quad I/O and to implement device-level authentication.

Engineers deploying firmware storage, XIP, or secure data storage can use this device where a 2.7 V–3.6 V supply, industrial temperature range and integrated security operations are required for reliable, space-efficient designs.
