W74M12JWSSIQ TR

The W74M12JWSSIQ TR is a 128 Mbit non-volatile NAND flash memory in an 8‑SOIC package, organized as 16M × 8. It implements a SPI – Quad I/O memory interface and supports clock operation up to 104 MHz.

Part of Winbond’s W74M Authentication Flash family, the device integrates hardware authentication primitives (including an HMAC‑SHA‑256 crypto accelerator and four monotonic flash counters) to add multi‑layer authenticity and integrity for IoT, industrial and embedded applications.

Key Features

• Memory  128 Mbit NAND flash organized as 16M × 8 for code and data storage in embedded systems.
• Interface  SPI – Quad I/O memory interface for standard serial flash communication and higher throughput using quad I/O modes.
• Clock Performance  Supports operation at up to 104 MHz for responsive read/write transactions in SPI modes.
• Security & Authentication  W74M family architecture includes an HMAC‑SHA‑256 crypto accelerator and four monotonic flash counters HMAC‑signed by individual secret keys, enabling multi‑layer authentication and resistance to reply attacks.
• Power  Narrow supply voltage range of 1.7 V to 1.95 V for low‑voltage system integration.
• Package & Temperature  Offered in an 8‑SOIC package (0.209" / 5.30 mm width) with an operating temperature range of −40 °C to 85 °C (TA).

Typical Applications

• Emerging IoT  Multi‑layer authenticity for connected devices where data integrity and anti‑tamper measures are required.
• Home Automation & Smart Home  Secure storage of firmware and authentication counters for devices such as controllers and secure peripherals.
• Industrial Control  Non‑volatile code and data storage with authentication features to protect firmware and configuration in industrial systems.
• Mobile Accessories  Low‑voltage flash storage with authentication primitives for accessory identification and anti‑cloning.

Unique Advantages

• Built‑in Authentication Engine: Hardware HMAC‑SHA‑256 and HMAC‑signed monotonic counters enable integrity and anti‑replay protection without adding external crypto components.
• Compact, Standard Package: 8‑SOIC footprint simplifies board layout and BOM for designs requiring a standard serial flash package.
• Low‑Voltage Operation: 1.7 V–1.95 V supply range supports low‑voltage system domains and power‑sensitive designs.
• Designed for Embedded Use: 104 MHz SPI clock capability and quad I/O support deliver practical throughput for code‑execute and data‑read scenarios.
• Wide Temperature Range: −40 °C to 85 °C operation addresses common commercial and industrial temperature needs.
• Manufacturer Support: Part of Winbond’s W74M family with design and production resources described in the product documentation.

Why Choose IC FLASH 128MBIT SPI/QUAD 8SOIC?

The W74M12JWSSIQ TR combines standard serial flash memory with integrated authentication features to address designs that require both reliable non‑volatile storage and built‑in integrity mechanisms. Its quad SPI interface and 104 MHz clock support responsive memory access while the low supply voltage and 8‑SOIC package simplify integration into space‑ and power‑conscious systems.

This device is suited for engineers developing IoT, consumer, and industrial products that need authenticated storage, anti‑cloning, or root‑of‑trust elements alongside conventional flash memory. Backed by Winbond’s product family documentation and manufacturing resources, it offers a practical balance of security features and memory functionality for embedded designs.
