W74M25JWZPIQ

The W74M25JWZPIQ is a 256 Mbit non-volatile NAND flash device in the Winbond W74M Authentication Flash family. It integrates a hardware HMAC-SHA-256 crypto accelerator and multiple monotonic flash counters designed to add multi-layer authentication to embedded designs.

Targeted for IoT, consumer and industrial applications, the device delivers authenticated storage and anti-cloning capabilities while operating at a 104 MHz clock rate and a low supply range of 1.7 V to 1.95 V.

Key Features

• Security Engine  Includes a standard HMAC-SHA-256 crypto accelerator for authenticated operations.
• Monotonic Flash Counters  Four separate monotonic flash counters are provided; each counter value is HMAC-signed using individual secret keys to support tamper-resistant sequencing and anti-replay measures.
• Authentication and Integrity  Enables verification of counter values and the ability to add timestamps to messages, providing resistance to replay attacks and strengthening code/data authenticity.
• Memory Type & Organization  Non-volatile NAND flash organized as 32M × 8 for a total of 256 Mbit.
• Clock Performance  Operates with a 104 MHz clock frequency for flash access.
• Supply Voltage  Low-voltage operation across a 1.7 V to 1.95 V range.
• Package  Available in an 8-lead WDFN exposed pad package; supplier device package listed as 8-WSON (6 × 5 mm).
• Operating Temperature  Specified for operation from −40 °C to 85 °C.

Typical Applications

• Emerging IoT  Adds multi-layered authenticity and authenticated storage for connected devices.
• Mobile Accessories  Provides authenticated code/data storage and anti-cloning protection for accessory modules.
• Home Automation & Smart Home  Secures firmware and configuration data against tampering and cloning.
• Industrial Control  Supports integrity verification and authenticated timestamps for control modules and firmware management.

Unique Advantages

• Multi-layer Authentication:  Hardware HMAC and monotonic counters enable layered integrity checks and anti-replay protection.
• Built-in Anti-cloning Features:  Individually HMAC-signed monotonic counters support anti-copy and anti-cloning implementations for PCBA and module protection.
• Low-Voltage Operation:  1.7 V–1.95 V supply range supports low-power system designs and modern power domains.
• Compact Package Options:  8-lead WDFN exposed pad / 8-WSON (6×5 mm) package choices enable space-constrained board designs.
• Wide Temperature Range:  −40 °C to 85 °C operation suits a broad set of consumer and industrial environments.
• Vendor Manufacturing Support:  Winbond’s in-house wafer fabrication provides supply and capacity flexibility as noted in the product information.
