W74M12JWZEIQ TR

The W74M12JWZEIQ TR is a 128 Mbit non-volatile NAND flash device in the Winbond W74M Authentication Flash family. It combines a 16M × 8 memory organization with an SPI Quad I/O interface and a 104 MHz clock rating to serve code and data storage needs in compact embedded designs.

Designed for systems requiring multi-layer authentication, the W74M family integrates an HMAC-SHA-256 crypto accelerator and four monotonic flash counters to strengthen code/data integrity and provide resistance to replay attacks for applications such as IoT, home automation and industrial control.

Key Features

• Security Engine Integrated HMAC-SHA-256 crypto accelerator for authenticated operations and integrity verification.
• Monotonic Flash Counters Four separate monotonic flash counters that are HMAC-signed by individual secret keys to support tamper-resistant timestamps and anti-reply mechanisms.
• Memory Capacity & Organization 128 Mbit FLASH organized as 16M × 8, suitable for code storage and secure data retention.
• Interface & Performance SPI — Quad I/O interface with a 104 MHz clock frequency to support high-speed serial access.
• Voltage Low-voltage operation from 1.7 V to 1.95 V (1.8 V class).
• Package Small footprint 8-pin WSON (8 × 6 mm) / 8-WDFN with exposed pad options for thermal and PCB mounting considerations.
• Operating Temperature Industrial temperature range from −40 °C to 85 °C (TA).

Typical Applications

• Emerging IoT — Adds multi-layered authenticity and secure storage for device identity, firmware integrity and anti-cloning protections.
• Mobile Accessories — Provides authenticated storage for accessory firmware and secret keys to prevent unauthorized copies.
• Home Automation & Smart Home — Secures device credentials and enables verified firmware updates for connected sensors and controllers.
• Industrial Control — Offers authenticated counters and integrity checks to protect critical configuration and operational code.

Unique Advantages

• Built-in Cryptographic Acceleration — HMAC-SHA-256 engine enables on-device authentication without external crypto components, simplifying secure design.
• Monotonic Counters for Anti-Replay — Four HMAC-signed flash counters allow systems to add tamper-resistant timestamps and resist replay attacks.
• High-Speed Quad SPI — Quad I/O SPI operation at up to 104 MHz provides fast serial access to code and data for responsive embedded systems.
• Low-Voltage Operation — 1.7 V–1.95 V supply supports low-power system domains and 1.8 V platform compatibility.
• Compact Package Options — 8-WSON/8-WDFN packages with exposed pad enable small PCB footprint and improved thermal mounting.
• Vendor Vertical Integration — Winbond’s in-house wafer fabrication supports capacity and delivery flexibility for long-term production needs.
