W74M25JWZEIQ TR

The W74M25JWZEIQ TR is a 256 Mbit NAND flash authentication device built for embedded systems that require non-volatile code and data protection. It integrates a 32M × 8 memory organization and supports operation at a clock frequency of 104 MHz.

Designed for security-aware applications, the device includes on-chip authentication features to strengthen integrity and anti-cloning measures for IoT, industrial control, and consumer accessory use cases while operating across a 1.7 V to 1.95 V supply range and an ambient temperature range of −40°C to 85°C.

Key Features

• Memory Type & Capacity  256 Mbit NAND flash organized as 32M × 8 for non-volatile code and data storage.
• Security Engine  Built-in HMAC-SHA-256 crypto accelerator and on-chip authentication primitives for integrity verification.
• Monotonic Counters  Four separate monotonic flash counters, each HMAC-signed by individual secret keys to support anti-replay and timestamped messaging.
• Performance  Supports a 104 MHz clock frequency suitable for embedded flash access patterns requiring moderate throughput.
• Supply Voltage  Operates from 1.7 V to 1.95 V, enabling use in low-voltage system domains.
• Package  Available in an 8-lead WSON (8 × 6 mm) / 8-WDFN with exposed pad package for compact board-level integration.
• Operating Range  Industrial temperature range from −40°C to 85°C for deployment in a variety of environments.

Typical Applications

• Emerging IoT  Adds multi-layer authentication to IoT devices where device identity and message integrity are required.
• Mobile Accessories  Protects firmware and configuration data in accessories that require anti-cloning and authenticated updates.
• Home Automation & Smart Home  Secures device authentication and integrity for connected sensors, controllers and smart modules.
• Industrial Control  Provides authenticated storage and monotonic counters for systems needing tamper-evident state tracking.

Unique Advantages

• On-chip HMAC-SHA-256: Hardware crypto acceleration enables authenticated operations without offloading to external processors.
• Monotonic, HMAC-signed Counters: Four independent monotonic flash counters signed by separate secret keys provide anti-replay and anti-cloning capabilities.
• Compact, Exposed-Pad Package: 8-WSON (8 × 6 mm) packaging with exposed pad supports small form-factor designs and board thermal management.
• Low-voltage Operation: 1.7 V to 1.95 V supply range suited to low-voltage system domains and power-constrained designs.
• Wide Temperature Range: Rated for −40°C to 85°C operation to cover a broad set of embedded and industrial environments.
