W74M25JWZPIQ TR

The W74M25JWZPIQ TR is a 256 Mbit non-volatile NAND Flash device from Winbond Electronics designed for authentication and secure code/data storage. It combines NAND Flash memory with on-chip authentication primitives—including an HMAC-SHA-256 crypto accelerator and monotonic flash counters—targeted at systems requiring multi-layered authenticity.

Typical use cases include emerging IoT endpoints, mobile accessories, home automation and industrial control modules where protection against cloning, tampering and replay attacks is needed while maintaining compact, low-voltage operation.

Key Features

• Security Engine  Integrated HMAC-SHA-256 crypto accelerator for authentication and integrity verification; supports multi-layer authentication workflows.
• Monotonic Flash Counters  Four separate monotonic flash counters that are HMAC-signed by individual secret keys to enable tamper-resistant timestamps and resistance to replay attacks.
• Memory Type & Organization  256 Mbit NAND Flash organized as 32M × 8, providing non-volatile storage for code, configuration and security data.
• Performance  104 MHz clock frequency for memory operations.
• Power  Low-voltage operation with a supply range of 1.7 V to 1.95 V.
• Package  Available in compact 8-lead WSON package (supplier device package: 8-WSON 6×5) and 8-WDFN with exposed pad options.
• Operating Temperature  Industrial temperature range from −40°C to 85°C.

Typical Applications

• Emerging IoT devices  Add multi-layered device authenticity and secure storage for firmware and credentials in constrained endpoints.
• Mobile accessories  Protect accessory firmware and enable anti-cloning measures for accessory modules.
• Home automation and smart home  Authenticate modules and secure configuration data in sensors, controllers and gateways.
• Industrial control  Provide tamper-resistant counters and message authenticity for control modules and firmware validation.
• PCBA anti-copy / IP protection  Use monotonic counters and HMAC-based signatures to deter cloning and protect software/IP on the board.

Unique Advantages

• Integrated authentication primitives: On-chip HMAC-SHA-256 accelerator and HMAC-signed monotonic counters reduce external cryptographic requirements and simplify secure design.
• Anti-replay and anti-clone capabilities: Monotonic flash counters signed by individual keys enable timestamping and strong resistance to replay and cloning attacks.
• Compact, low-voltage solution: 256 Mbit density in an 8-lead WSON/WDFN package with 1.7–1.95 V supply fits space- and power-constrained designs.
• Industrial temperature range: −40°C to 85°C operation supports a wide range of embedded environments.
• Designed for secure code/data storage: Combines NAND Flash storage with built-in security to help protect firmware, credentials and IP on-device.
